Pemphis

Pemphis is a genus of maritime plants in family Lythraceae. It was recently thought have only one species (the type species, described in 1775, Pemphis acidula [2]) but is now believed to have at least two.[3]

Pemphis are highly adaptive. Depending on environmental factors, they are densely branched, or low and spreading bushes or short trees, with main stems that can be furcated and lie nearly prone, or develop into one erect trunk. Leaves can be small, fleshy and succulent, or larger, flat and not fleshy. All surfaces are covered generally in silky, colorless trichomes.[4] The fruits and bee-pollinated flowers are produced throughout the year. Seeds can float, and are sometimes propagated through water dispersal.[5]

Habitat

Most Pemphis live either at the verges of mangrove forests, well away from the forest-ocean interface; or they colonize beaches behind the intertidal zone, taking hold on rocks, gravel or sand, laterite or limestone, and frequently on promontories or crags.[5]

Range and distribution

They are not common, but far ranging from coastal, eastern Africa (including the Seychelles,[6] and the Zanzibar Archipelago[5]), states with Indian Ocean coastlines, to the Pacific (Philippines,[7] Cook Islands[8]), northwards up to Taiwan and the Ryukyu Islands[4] Other places reporting Pemphis include mainland coastal Tanzania, Thailand, Malaysia (Johore), Singapore, Indonesia (Papua, Sumatra, the Moluccas, Madura and Java), Papua New Guinea, Hong Kong and throughout tropical Australia. On Java in particular (where it is known as stigi or santigi), some areas are uncharacteristically abundant.[5]

Uses

Despite the difficulty presented for the prospective carver, wood from Pemphis species is highly prized for its extreme heaviness, toughness and resistance to warping. It is usually fashioned into walking canes, fence posts, tool handles, and even anchors, exhibiting a fine finish.[5]

Pemphis acidula is a valuable tropical species for bonsai, particularly in Asia.[9]

gollark: Those are specific uses of some of those things, yes. Which is why those are important. Although programming isn't intensely mathy and interest is trivial.
gollark: I assume you mean interpersonal? School is really bad for that as it stands because you're artificially segmented into people of ~exactly the same age in a really weird environment.
gollark: *Ideally*, at least, school works as a place to learn things from those who know them well and discuss it with interested peers.
gollark: Unfortunately, this is implemented poorly.
gollark: I don't really agree. It is not practical to guess what directly applicable skills will be needed in the future. It should teach general skills like learning independently fast, mathematical modelling, useful writing, languages, and that sort of thing.
