Pouteria


Pouteria is a genus of flowering trees in the gutta-percha family, Sapotaceae. The genus is widespread throughout the tropical Americas, with outlier species in Cameroon and Malesia. It includes the green sapote, the mamey sapote, and the abiu. Commonly, this genus is known as pouteria trees.
Pouteria is related to Manilkara, another genus that produces hard and heavy woods used commonly for tropical construction, as well as edible fruit.

Range

Pouteria, as currently delineated, has 170 species in the tropical Americas, from Mexico to northern Argentina and central Chile, including Florida and the Caribbean islands. Four species are found outside the Americas. Pouteria hexastemon is native to Cameroon in west-central Africa, and three species are native to IndonesiaPouteria celebica to Sulawesi, Pouteria lucida to Maluku, and Pouteria oxyedra to Sumatra.

Uses

Many species, such as Pouteria sapota, 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, 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 of Pouteria wood can be in excess of 1140 kg/m3 |medullary ray]s 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.
Due to habitat loss and in some cases overexploitation, many species of Pouteria are threatened. At least 10 are close to extinction.

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 synonymized with Pouteria. Most segregated genera that were merged with Pouteria again were established by Henri Ernest Baillon and Jean Baptiste Louis Pierre.
Recent phylogenetic and morphological studies found Pouteria to be polyphyletic, and many genera previously subsumed into Pouteria and/or Chrysophyllum, including Achrouteria, Chloroluma, Cornuella, Englerella, Labatia, Lucuma, Martiusella, Nemaluma, Peteniodendron, Prieurella, and Ragala, have been reinstated.
