What is mahogany? ... Are you sure?

            

Mahogany has been used as a tonewood for many years.

Apart from being wood, what is mahogany, and why should you be interested? You may be surprised. The modern use of the word mahogany may not necessarily mean what you think it means!

In guitar-making what we regard traditionally as "mahogany" is the timber of only one of 49 genera that belong to the botanical family Meleaceae (Mahogany family.) This genus is called Swietenia, native to Central and South America and the Caribbean. It has three species:

1. Swietenia mahagonitraded under the specific names Caribbean Mahogany, Cuban Mahogany, or West Indian Mahogany. It is native to southern Florida and the West Indies. It was the first species of mahogany used in the manufacturing of guitars until the 1950's. It has been commercially extinct since 1947.

2. Swietenia humilis, traded under the specific names Honduras Mahogany, Pacific Coast Mahogany or Mexican Mahogany. It is is native to Costa Rica, El Salvador, Guatamala and Mexico. There are very few populations left and it is used mainly in local carpentry.

3. Swietenia macrophylla, traded as Brazillian Mahogany, Genuine Mahogany, or Big Leaf Mahogany.  It is native to the Atlantic side of Central America as well as much of South America. This species has been the one used for making guitars. However, since 2003 it has become commercially extinct with the exception of some limited supply from Brazil, Peru and Bolivia, under heavy restrictions.

Note. All three species are sometimes individually and collectively called American mahogany .

Swietenia mahagoni         Swietenia humilis         Swietenia macrophylla

What happened? In simplicity: overlogging and illegal trade over about 85 years has brought all species of Swietenia mahogany to near extinction. Since 1950 Central American populations have suffered a 70-90% decline.

Unfortunately it wasn't until the 1990's that the inevitable outcome was fully recognized and specific measures were taken internationally to try and save the resource from future extinction.

The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) is an international agreement between nations to uniformly police threats to the survival of plants and wild life due to human abuse. Formed in 1973 and passed in 1975 there are currently 180 "contracting parties" (nations) on the list as of 2014. Each party has their own legislation which aligns with the agreement. An example is the Lacey Act of the United States which exists to police and control illegal import and export of banned or restricted plants and substances and wild life, effective from 2008.

CITES has three different levels of protection for species, known as Appendices:

Appendix I – This appendix represents species that are in the most danger and are considered to be threatened with extinction, and are consequently the most restricted in international trade.

Appendix II – This appendix contains species that are at risk in the wild but not necessarily threatened with extinction. Species in this appendix are closely regulated but are typically not as restricted as Appendix I.

Appendix III – This appendix contains species that a certain country (contracting party) has voluntarily requested to be regulated in order to help preserve the species in question. Appendix III species regulation is only applicable for the specific party that has requested its inclusion and is therefore much less restrictive than Appendix I or II. 

All three species of Swietenia are listed on CITES Appendix II: Swietenia humilis in January 1975, Swietenia mahagoni in November 1992 and Swietenia macrophylla in November 1995. Efforts to save the resource have become a major project of CITES. Throughout the 2000's there has been much work done to forward efforts to conserve the resource and to explore alternatives for reforestation and sustainability on a worldwide scale.

Unfortunately, efforts to repopulate mahogany in it's native locations throughout the 2000's turned out to be largely unsuccessful. There are four major reasons why Swietenia can no longer be re-grown natively: 

1. the soil is now depleted and barren.

2. The aggressive mahogany shoot borer Hypsipyla grandella kills the new trees. Modern Science has not managed to overcome this.

3. genetic loss means that the current generations of seeds for planting are inferior and/or mutated.

4. erosion has taken place where large forests have been cleared leaving those areas now uninhabitable. 

In order to save Swietenia mahogany from impending extinction Authorities were forced to look beyond it's native locations to find solutions to the problem.

Attempts to grow Swietenia in Africa resulted in uniform failure and abandonment due to attacks by the Asian and African equivalent mahogany shoot borer Hypsipyla robusta. Europe was not considered as it does not have the right climate to grow it. 

It turns out that Asia and the South Pacific are the most successful areas where Swietenia can be grown outside of its native locations. Following initial trials a number of Asian countries were consulted with and invested in to develop controlled, sustainable and renewable Swietenia mahogany plantations. This started mostly in the 1990's and was helped along by the 1993 World Bank report entitled "Tropical Hardwood Marketing Strategies for Southeast Asia".

In actual fact, some Asia-Pacific countries had already been growing Swietenia for a very long time! 

Fiji had Swietenia plantations since the 1950's using seeds originally from Honduras and Belize. Fiji is a major producer and international supplier of new American mahogany today having been corporatized since 1998. 

India had both Swietenia macrophylla and Swietenia mahagoni introduced in 1865 using seeds from West Indies.

Indonesia, the world's largest producer of plantation mahogany today, had Swietenia mahagoni and Swietenia macrophylla introduced in 1870 using seeds from India. Over 60% of the world's supply of plantation American mahogany today comes from Indonesia.

Swietenia macrophylla was originally planted in Sri Lanka in 1897 but it wasn't really until the 1950's that plantations were consciously established. Then again it wasn't until the 1990's that any real significant investment was undertaken to take control of the unmanaged plantations which had since become naturalized forests. 

Swietenia mahagoni was introduced into Malaysia in 1876 and Swietenia macrophylla in 1886 and 1892. Both species were attacked by Hypsipyla robusta and further planting was abandoned. In recent times Malaysia has become involved with plantation mahogany since about 1998.

The largest Swietenia mahogany plantation in the Philippines which began in 1982 is now a major international exporter of American mahogany today, with other investment and development of Philippine plantations occurring after the 1993 World Bank report. Swietenia macrophylla is the third most planted species in the Philippines.

Other countries that have become involved in developing sustainable Swietenia plantations are Solomon Islands (1989), India (ca. 1990), Bangladesh (ca. 1993), Thailand (ca. 1994), Malaysia (ca. 1998), and Taiwan (ca. 2002). As mahogany has a 35-40 year rotation, quality harvesting from some of these countries is still many years away.

CITES restrictions do not apply to Asian-grown Swietenia mahogany as their plantations are sustainably managed and controlled. 

Despite international efforts, illegal logging is still taking place in some parts of South America today with 80% of this illegal timber being supplied to the USA by criminal operations. Some sources have even predicted that South American-grown Swietenia may become extinct by 2016. 

Mahogany other than Swietenia

Swietenia is not the only genus in the Mahogany family that yields high quality timber. In total there are 49 genera with approximately 550 species in the Mahogany family. Some have timber uses and some are even used as direct replacements for Swietenia. Others are merely plants and may only produce fruit, oil and seed often used for medicines or lotions. Of the ones that do yield timber, some include the word mahogany in their trade name and others do not. There are two terms to know:

1. Genuine Mahogany as a term applies to mahogany of the Swietenia genus only, wherever grown.

2. True Mahogany describes the timber of any Mahogany  family genus other than Swietenia.

Some of the non-Swietenia mahoganies in use are:   

AFRICAN MAHOGANY

khaya anthotheca   khaya grandifolia1   khaya ivorensis1   khaya senegalensis   khaya  madagascariensis
   K. anthotheca     K. grandifoliola       K. ivorensis    K. senegalensis    K. madagascariensis 

Khaya is a Mahogany family tree native to temperate Africa and Madagascar. It has 5 species. All species are collectively traded under the name African Mahogany. Khaya is the most accepted Mahogany family timber other than Swietenia to be called mahogany without qualification. It is probably the most popular Swietenia replacement. Variations in trade names are usually determined by where it is sourced. Khaya grandifoliola which is native to Benin, the Democratic Republic of the Congo, Ivory Coast, Ghana, Guinea, Nigeria, Sudan, Togo, and Uganda is also called Benin MahoganyKhaya ivorensis which is native to Angola, Cameroon, Côte d'Ivoire, Gabon, Ghana, Liberia, and Nigeria is also called Lagos MahoganyKhaya senegalensis is found in Benin, Burkina Faso, Cameroon, Central African Republic, Chad, Ivory Coast, Gabon, Gambia, Ghana, Guinea, Guinea-Bissau, Mali, Niger, Nigeria, Senegal, Sierra Leone, Sudan, Togo, and Uganda and also called Senegal Mahogany or Dry Zone Mahogany. Plantations now exist in Malaysia, Sri Lanka and northern Australia. Khaya madagascariensis is found in Madagascar and Comoros and is often simply called Madagascar MahoganyKhaya anthotheca grows in Angola, Guinea Bissau, Tanzania, Uganda, Zambia, Zimbabwe and Mozambique and is also known as East African Mahogany or White Mahogany. It is also grown in plantantions in South Africa and Asia. The wood of Khaya senegalensis and Khaya grandifoliola resembles Swietenia more closely than the wood of Khaya anthotheca and Khaya ivorensis, but they are heavier and harder. All species are subject to habitat loss and are currently under inspection by CITES for recommending restrictions. "Serious genetic erosion" has been reported to have occurred in areas which have been exploited. All species are currently listed as "vulnerable" on the IUCN Red List of Threatened Species. The United States has always been the largest importer of African mahogany.

TOON

t.sinensis         t.ciliata         t.sureni         t.calantas
   Toona sinensis              Toona ciliata             Toona sureni            Toona calantas

Toonbotanical name Toona, is a Mahogany family tree native throughout eastern Europe, northern Asia, and South East Asia. In SE Asia the wood is considered of high value and is used in house and ship building, for joinery, high-grade furniture, tea chests and boxes, musical instruments, toys and novelties, carvings, veneer, plywood and pencils. It is probably the most sought after true mahogany today for higher quality factory-made guitars where mahogany is specified. As a tonewood it is very similar to Swietenia. There are four species, each with their own trade names :

1. Toona ciliata is traded as Indian Mahogany. It is native to Bangladesh, Cambodia, China, India, Indonesia, Laos, Malaysia, Nepal, Pakistan, Papua New Guinea, Philippines, Thailand, Vietnam, and Australia. The Australian species is called Red Cedar but is no longer commercially available due to overlogging. Toona ciliata is the most common Toon species exported from Asia. 

2. Toona sinensis is traded as Chinese Mahogany. It is native to eastern and south eastern Asia; stretching from eastern India, China, Nepal, North Korea, Burma, Thailand, Malaysia, to western Indonesia. 

3. Toona sureni is traded as Indonesian MahoganyVietnamese Mahogany or Suren. It is native to Bhutan, China, India, Indonesia, Malaysia, Myanmar, Nepal, Papua New Guinea, Philippines and Thailand. It is important to know that Indonesia is one of the largest world suppliers of plantation-grown Swietenia mahogany today. It is therefore necessary to differentiate between the term "Indonesian Mahogany" as Toona and "Indonesian Mahogany" as plantantion Swietenia.

4. Toona calantis is traded as Philippine Mahogany, or Calantis. It is native to Indonesia, Malaysia, and Philippines. This species was put on the IUCN Red List Of Threatened Species in 2006 and has felling restrictions.

IMPORTANT. "Philippine Mahogany" is also a generic term used in the USA carpentry trade and internationally to describe timbers from the Shorea species which is botanically unrelated to the Mahogany family. It consists of 196 species in the Dipterocarpaceae family native to much of Asia. 148 of the 196 species are threatened with habitat loss and have varying degrees of trade restrictions. It is possible to confuse this term, being that Philippine Mahogany could be 1) a Shorea, 2) Philippine Toona, or 3) plantation Swietenia grown in the Philippines.  

SPANISH CEDAR

spanish_cedar

Spanish Cedar, (also called Cedro or Red Cedar) botanical name: Cedrela odorata, is one of 9 species of Cedrela, a Mahogany family tree native to northern Mexico, central America, the Caribbean islands, and Brazil. Botanically Cedrela is the equivalent of Asian Toona except that it is native to the neo-tropics. Cedrela odorata was for a long time a very important Latin American timber, second to Swietenia. It was commonly used for making cigar boxes but it was also used for light construction, joinery, mouldings, panelling, louvred doors, boat building, furniture, cabinet work, weatherboards, boxes, household implements, musical instruments, carvings, veneer, plywood, turnery and matchboxes. It has been used for necks, tops and sides of classical and flamenco guitars and a veneer or cap on electric guitars. The timber of two other Cedrela species have sometimes been used interchangeably: Cedrela fissilis, native to  Argentina, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, Panama, Paraguay, Peru, Suriname and Venezuela; and Cedrela lilloi, native to Argentina, Bolivia, Brazil, Paraguay, and Peru. Both are nearly extinct and are each are listed on the IUCN Red List as "endangered." Cedrela odorata  is listed on the IUCN Red List as "vulnerable." Woods from Columbia and Peru were added to CITES Appendix III in 2001. Wood from Guatamala was added to Appendix III in 2008. Bolivia requested its 3 species be added to Appendix III in 2010, followed by Brazil in 2011. As with the Swietenia species, all native Cedrela is susceptible to Hypsipyla grandella attack. Cedrela odorata plantations exist in Mexico and elsewhere in Africa, specifically in Côte d’Ivoire, Ghana, Uganda, Tanzania, Madagascar and South Africa. In Ghana Cedrela odorata was planted along roads as early as 1898, and is now one of the most frequently planted species in African forest plantations. In Tanzania it was introduced in 1911, in Nigeria in 1929. In Côte d’Ivoire more than 9900 hectares were planted between 1963 and 1995. As of 2013, there are little to no exports of Cedrela odorata from Africa other than from Ghana. 

SAPELE 

sapele

Sapele (also called Sapelli), botanical name Entandrophragma cylindricum, is one of 11 species of Entandrophragma, a Mahogany family tree native to tropical Africa. It comes mainly from Cameroon, Congo, Ivory Coast and Ghana. It is used for backs and sides of acoustic guitars and tops of electric guitars. It is identifiable by having sweeping, striped grain and varies in colour from reddish to purple-brown. It's sound properties are very close to Swietenia mahogany. Sapele is not listed in the CITES Appendices, but is now on the IUCN Red List. It is listed as "vulnerable" due to a population reduction of over 20% in the past three generations, caused by a decline in its natural range, and exploitation. Some countries have their own protected populations and felling restrictions in place. 

SIPO / UTILE 

utile

Sipo (also called Sipo Mahogany or Utile), botanical name Entandrophragma utile is another African Entandrophragma species very suitable for guitar manufacturing. It's properties are slightly more closer to Swietenia mahogany than it's Sapelli sibling although visually it is generally slightly less grained than Sapelli. It can be used for the same things in guitar manufacturing as Sapelli. Utile is otherwise used for furniture, exterior joinery, construction and boat building. It is more popular in Europe than the United States where instead Sapelli is the dominant of the two. It comes mainly from the Central African Republic and Congo, a major exporter to Europe. As with Sapelli it is now on the IUCN Red List.

TIAMA MAHOGANY 

tiama

Tiama Mahogany (also called Gedu Nohor or simply Tiama) botanical name Entandrophragma angolense is another of the 11 species of Entandrophragma occurring throughout western, central and southern Africa. The wood is highly valued for exterior and interior joinery, furniture, cabinet work, veneer and plywood, and is also used in Africa for flooring, interior trim, panelling, stairs, ship building, vehicle bodies and coffins. It is suitable for light construction, musical instruments, toys, novelties, boxes, crates, carvings and turnery. It is one of the most valued export timbers from Ghana. Most Tiama mahogany is exported to Europe. In Ghana and Uganda it is now considered threatened. It is included in the IUCN Red list as "vulnerable." 

GUAREA

guarea cedrata         guarea_thompsonii         guarea_grandifolia
Guarea cedrata         Guarea thompsonii         Guarea grandifolia

Guarea is a Mahogany family genus with 43 species, three of which have timber uses: Guarea cedrata and Guarea thompsonii which are native to Africa and traded as Bosse or Pink Mahogany, and Guarea grandifolia which is native to Central and Latin America and traded as American Muskwood. It resembles Khaya (African mahogany) in appearance and is botanically very close to Sapelli mahogany. The wood is valued for house building, flooring, joinery, interior trim, panelling, window frames, doors, ship building, vehicle bodies, furniture, cabinet work, decorative boxes, crates, veneer and plywood. It is suitable for musical instruments, toys, novelties, carving and turnery. The African species were a major export timber but is now endangered in some countries. In America it is a widely accepted mahogany substitute and is used in the manufacturing of acoustic guitars.

EAST INDIAN MAHOGANY

chuckrasia_tabularis 

East Indian Mahogany, botanical name: Chukrasia tabularis, is also known as Chickrassy, Chittagong Wood, Indian Mahogany, or White Cedar. This Mahogany family tree is native to India, Bangladesh, China, Burma, Laos, Cambodia, Vietnam, Malaysia, and Sri Lanka. It has also been introduced into Southern Africa and the Caribbean. In tropical Asia the wood is highly prized for high-grade cabinet work, decorative panelling, interior joinery such as doors, windows and light flooring, and for carving, toys and turnery. It is also used for light to medium-heavy construction work, e.g. for posts, beams, scantlings and planks, and for railway sleepers, ship and boat building, furniture, musical instruments (especially pianos), packing cases, sporting goods, truck bodies, mallet heads, anvil blocks, brush wares, drawing equipment, rifle butts, veneer and pulp. Botanically it is very close to Cedrela and Toona.

CACHARANA

cancharana

Cacharana, Cangerana or Cajarana, botanical name: Cabralea canjerana is a Mahogany family tree found only in South America and pretty much unknown to the rest of the world. It has no equivalent English name. There is not even an English Wikipedia entry for it. It is native to Argentina, Brazil, Paraguay, and Uruguay. Widely available in Brazil, it is used in local general carpentry, furniture, interior construction, carvings and joinery. It's colour is usually a dull red or maroon often with purplish markings. Gibson Guitars has used it as a top on their Les Paul "Smartwood" models and other South American luthiers use it for bodies and necks of electric guitars. From what little I know it appears to be a very good tonewood and an ideal replacement for Swietenia. As it only has a Spanish name I am going arbitrarily christen it "New World Mahogany" for the English-speaking world. It's as good a name as any. Maybe it will catch on?

NATAL MAHOGANY

natal mahogany

Trichilia is a Mahogany family genus with 42 species, 4 of which are native to southern, central and eastern Africa, and the rest native to South America and some parts of the Caribbean. Most of the South American species are endangered by habitat loss. Trichilia emetica is one species native to South Africa and is known there as Natal Mahogany or Cape Mahogany. It's wood is a pink colour. Timber uses include carvings, traditional African musical instruments, household implements, furniture, bats and canoes. The oil is used locally as a topical medicine. Trichilia dregeana is known in South Africa as Forest Mahogany. These two southern African mahogany species are largely unknown to the rest of the world as neither appear to be an export product (?)  

ROYAL MAHOGANY

carapa

Royal Mahogany, botanic name: Carapa guianensis, is better known as Andiroba or Crabwood  and is a Mahogany family tree native to Central and South America. Its heartwood has colour varying from light salmon to reddish-brown that darkens with time to a medium to dark shade. It is an ideal timber for furniture, cabinetry, mouldings, windows and doors, joinery, paneling, and medium to light construction. It has a similar appearance to Swietenia, often with more "swirl" to the grain. It is the third most important export timber from Brazil, behind Cedrela and Swietenia. It is apparently used in South America as a tonewood, for acoustic guitars and ukuleles. There are two other species: Carapa proceraone, native to West Africa (called African Crabwood or Okoto) and Carapa megistocarpa native to Ecuador (called Tangare.)

NEW ZEALAND MAHOGANY 

kohekohe

New Zealand Mahogany, botanic name: Dysoxylum spectibile is a Mahogany family species native to New Zealand and is one of the 80 species of Dysoxylum which is endemic to much of Asia and Oceania. It's local name is Kohekohe. It grows mainly in North Island and northern parts of South Island. New Zealand mahogany is softer than other Mahogany family timbers and is used in general carpentry. It is not desirable as a tonewood. New Zealand Kohekohe should not be confused with the plant of the same name which is native to Hawaii.  

ROSE MAHOGANY

dysoxylum_fraseranum

Rose Mahogany, botanical name: Dysoxylum fraserianum, is native to eastern Australia and is one of the 80 species of Dysoxylum, which is a Mahogany family timber native throughout Oceania and some parts of southern Asia. This Australian species is more often called Rosewood. I have seen it used as a body wood in Australia-made guitars. Another eastern Australian variant Dysoxylum mollissimum subsp. molle, is known as Miva Mahogany, Red Bean or Onionwood. Both species are used for furniture, plywood, shop and office fixtures, carving, turnery, and joinery. 

SCENTLESS ROSEWOOD

scentless rosewood

Synoum is another Australian Mahogany family genus with two species: Synoum muelleri called Scentless Rosewood, and Synoum glandulosum called Red Sycamore. Both are used in Australian construction for general house framing, flooring, mouldings and joinery as well as for furniture, shop and office fixtures, panelling, turnery, and carving. It is not considered a first class timber and I am unaware of this being used as a tonewood for musical instruments. 

CHINABERRY 

chinaberry  

Chinaberry, botanical name: Melia azedarach, also known as Bead-Tree, Cape Lilac, Persian Lilac, and White Cedar is a Mahogany family tree native to Pakistan, India, South East Asia and Australia that yields a high quality reddish-brown timber used in Asia to manufacture agricultural implements, furniture, plywood, boxes, poles, tool handles etc. It is used in cabinet making and in construction because of its resistance to termites. It is one of 12 species of Melia. It's fruit are poisonous to humans and animals. It is suitable as a tonewood and can be used for bodies of electric guitars. There is no commercial trade in it at this time as it is considered invasive and for this reason is commercially ignored. Outside of Asia it is of interest mainly to hobbyists.  

Non Mahoganies traded as Mahogany

In addition to "genuine" and "true" mahogany family timbers, there are other timbers which have no botanical relation to the Mahogany family at all, yet have a trade name that includes the word mahogany in it. It may be important to know these substitute timbers so that one can make a distinction when or if required. These botanically unrelated timbers may share similar appearances or tonal qualities to genuine or true mahogany, but that is all. Often the so-called "mahogany" trade name is not the main or only trade name.  

Philippine Mahogany, from the point of view of the USA furniture industry is clearly defined by the Federal Trade Commission, Code of Federal Regulations Title 16, Section 250.3 Identity of Woods: "The following non mahogany timbers may legally be called 'Philippine mahogany' in the USA: Tanguile, LauanTiaong, Almon, Mayapis and Bagtikan. ..." As mentioned above these timbers are varies species of Shorea which are native to Malaysia, Indonesia, Philippines and Thailand. Outside of the United States the term Philippine Mahogany applies to Lauan from Philippines, the various types of Meranti from Malaysia, Seraya from Indonesia, and Balau which is native to all. In Australia we also call them Pacific Maple. These timbers range in colour from grey to dark reddish brown and are usually used as veneers or plywood. Visually they are a lot more grainier than real mahogany. Remember though that the term Philippine mahogany could also refer to native Philippine Toona, or plantation Swietenia grown in the Philippines.

balau   lauan   light-red-meranti   white meranti   dark red meranti
          Balau             Lauan    Light Red Meranti       White Meranti    Dark Red Meranti

Cherrry Mahogany. Scientific name: Tieghmella heckelli and Tieghmella africana is one of the trade names for Makore, which is also known as African Cherry. It's main uses are for furniture, boatbuilding, and cabinetry as well as veneer. As a tonewood it is very similary to genuine mahogany and is used as a laminate for the tops of acoustic guitars and for electric guitar bodies. It is also used in making drums. Colour is pink to reddish-brown and sometimes it can have an attractive figure. It grows throughout western Africa and although not a Mahogany family genus is very similar in properties to Khaya (African mahogany.)

Santos Mahogany. Scientific name: Myroxylon balsamum. Native to Mexico, central and southern America this timber is stronger and harder than mahogany but shares a similar appearance. It is used in furniture, flooring and heavy construction. It has been used for making acoustic guitars and has been said to be similar in tone to American and African mahogany but with deeper lows. 

Red Mahogany. Scientific name: Eucalyptus resinifera is a hardwood native to eastern Australia and used for furniture, flooring, panelling, boat building and general construction. It has been introduced into Southern Africa, Italy and Portugal, and Hawaii as a plantation crop. It is not suitable for making musical instruments. Much of the 4500 hectares of red mahogany plantations in Queensland Australia were destroyed by Cyclone Yasi in 2011.  

Swamp Mahogany, botanical name Eucalyptus robusta is native to a narrow coastal area in south-eastern Australia, from southern Queensland to southern New South Wales. It is one of the most widely planted Eucalyptus species and it has been introduced into many tropical, subtropical, and warm-temperate areas internationally especially in Asia and tropical Africa. It is especially important in Madagascar, where it was introduced in the 1890s. The wood is generally used for construction, poles, ordinary furniture, wheels, boat building, wharf construction, shingles, pallets and boxes. The wood is also suitable for mine props, railway sleepers, vehicle bodies, agricultural implements, food containers, joinery, turnery and musical instruments. 

White Mahogany. Scientific name: Eucalyptus acmenoides is another of the 800-odd Australian eucalypts. It is abundant in Australia and used for construction and furniture. Local alternative names are Barayly and Yellow Stringybark. I am not aware of this timber being used as a tonewood.

East Indian Mahogany. Scientific name: Pterocarpus dalbergioides. Native to the Andaman Islands of India and some parts of mainland India, this timber is also traded under the name Andaman Padauk or Narra.  It is a major export timber from India and bears visual similarity to mahogany although much redder. It is used as a rosewood substitute in acoustic guitar making. There is an African equivalent, Pterocarpus soyauxii usually traded as African Padauk or Vermillion which is renowned as a tonewood for both acoustic and electric guitars.

Eastern Mahogany. Scientific name: Palaquium is one of 65 genera in the Sapotaceae family with 7 principal species that yield high quality hardwood. Species exist throughout Thailand, Malaysia, Philippines, Indonesia, Papua New Guinea, Solomon Islands and Fiji. It is also called Nato (Philippines), Nyatoh (Malaysia), Nyatuhin (Indonesia) and Masang (Thailand.) It ranges in colour from pink to red-brown. It varies wildly in weight and density and is predominately used for interior joinery, furniture, plywood and some craft applications. Recently it has found it's way as a mahogany replacement in entry-level Asian-made musical instruments. Another Sapotaceae genus, Payena has 20 species, 5 of which are principal sources of commercial timber and are also traded as Nyatoh. There are no CITES restrictions on Palaquium or Payena.

Borneo Mahogany. Scientific name: Calophyllum inophyllum is native to eastern Africa, Asia, the south Pacific and Australia. It is one of 187 species, most of which are found in Asia. No species exist in Europe. It goes by many names, some of the common ones being LaurelwoodRed Poon and Bintangor. The timber from this and other species in the genus are used for boat building, furniture, flooring and plywood. It is used for backs and fronts of entry-level acoustic guitars.

Asian Mahogany. Scientific name: Dipterocarpus is a South East Asian medium hardwood timber of about 70 species better known as Keruing. It is used for furniture and flooring only and is usually a reddish-brown across the species. It is not suitable as a tonewood and to call it "Asian mahogany" is really just a weak marketing ploy to make it sound like something it isn't. 

Summary

1. There is only one genus in the Mahogany family that is considered to be "genuine" mahogany. This is Swietenia.

2. Natively grown Swietenia is almost extinct and what's left is heavily restricted.

3. "Genuine mahogany" as a term applies to Swietenia only.

4. "True mahogany" as a term applies to Mahogany family timbers in use that are not specifically Swietenia such as  Khaya, Cedrela, Toona, Carapa, ChukrasiaEntandrophragma, Guarea, Dysoxylum, and Trichilia. Not all true mahoganies are suited as tonewoods.

5. Fiji, Indonesia and Philippines are the major suppliers of plantation Swietenia mahogany today.   

6. At this time Swietenia cannot be regrown in it's native locations due to permanent damage to the environment and unsolvable problems with pests. 

7. There are other timbers that have no botanical relation to the Mahogany family but are traded as "mahogany" in name only. Often these have other trade names which may also be better known. 

8. You may need to ask more questions when someone talks about "Indian mahogany", "Indonesian mahogany" or "Philippine mahogany" etc. It could be either native Toona or plantation-grown Swietenia. Or in the case of "Philippine Mahogany" it might be something that has no relation to real mahogany at all.

9. No guitars made in a factory (mass-produced) are made of genuine mahogany. Zero.

10. Only high-end custom shop guitar builders make instruments with genuine mahogany. if it is genuine mahogany (Swietenia) it will be plantation-grown or possibly American mahogany obtained before the ban (over 10 years ago.) Expect to pay at least $3000 for any electric guitar or bass made of genuine mahogany. $1000 guitars are never made of genuine mahogany. Sub-$1000 guitars are usually made out of rubbish.
