Pouteria Decorticans

''Pouteria'' is a genus of flowering trees in the gutta-percha family, Sapotaceae. The genus is widespread throughout the tropical regions of the world. It includes the canistel ('' P. campechiana''), the mamey sapote ('' P. sapota''), and the lucuma ('' P. lucuma''). Commonly, this genus is known as pouteria trees, or in some cases, eggfruits.

''Pouteria'' is related to ''Manilkara'', another genus that produces hard and heavy woods (e.g. ''balatá'', ''M. bidentata'') used commonly for tropical construction, as well as edible fruit (such as sapodilla, ''M. zapota'').

Uses

Many species, such as ''Pouteria maclayana'',Paper from the Research School of Pacific and Asian Studies
/ref> have edible fruits and are important foods, seasonally. Some are being commercially collected and sold on local markets or packed in cans.

''Pouteria'' species yield hard, heavy, resilient woods used as firewood and timber, but particularly in outdoor and naval construction, such as dock pilings, deckings, etc. Some species, such as abiu ('' P. caimito''), are considered to be shipworm resistant, but this depends on the silica content, which may vary from 0.0-0.9%. The weight by volume (at 12% moisture content) of ''Pouteria'' wood can be in excess of 1140 kg/m³ (71 lb/ft³; thus, the wood sinks in water. The wood of ''Pouteria'' species is prone to considerable movement and warping when it dries out, but in its main use, naval construction, this is not a problem, since the wood never gets really dry.

The vessel elements are relatively small and usually di- to quadriseriate; the medullary rays are fine and close together. ''Pouteria'' woods are capable of attaining an excellent polish using fine-grained sandpaper and possibly some wax. They can sometimes show an attractive figure of dark stripes against a sandy to mid-brown background colour. However, the wood is hardly used for furniture because it is so dense that items made from it would be difficult to transport. Moreover, it is nearly impossible to work using hand tools. Even using power tools, working these woods presents some problems, as well, but given some patience and practical knowledge, these can easily be solved.

For the silica to be effective against shipworms, it needs to dry to some degree to harden. When the wood is continually waterlogged, this process may take place very slowly or not at all, leaving the wood vulnerable.

''Pouteria'' foliage is used as food by some Lepidoptera caterpillars, including those of the dalcerid moth ''Dalcera abrasa'', which has been recorded on '' P. ramiflora''. The fruits are important food for various animals, such as the rock-haunting ringtail possum (''Petropseudes dahli'').

Due to habitat loss and in some cases overexploitation, many species of ''Pouteria'' are threatened. At least 10 are close to extinction, and one – the Rio de Janeiro pouteria ('' P. stenophylla''), which grew near Rio de Janeiro in Brazil, is now extinct.

Systematics and taxonomy

''Pouteria'' is a "wastebasket taxon", and its size is continually being expanded or decreased. The segregated ''Labatia'', described by Olof Swartz in 1788 and named after the French botanist Jean-Baptiste Labat, was maintained as a distinct entity until the 1930s, when it was finally synonymized with ''Pouteria'' for good. Most segregated genera that were eventually merged with ''Pouteria'' again were established by Henri Ernest Baillon and Jean Baptiste Louis Pierre.USDA (2009)
