Family Sapotaceae

Trees or shrubs , usually producing latex. Leaves spirally arranged or alternate and distichous, rarely ± opposite, sometimes crowded at apex of branchlets ; stipules early deciduous or absent; leaf blade papery or leathery, margin entire. Flowers bisexual or unisexual , usually in sessile axillary clusters , rarely solitary; cluster pedunculate or in raceme-like inflorescence, bracteolate . Calyx a single whorl of usually 4--6 sepals, or 2 whorls each with 2--4 sepals. Corolla lobes as many to 2 X as many as sepals, usually entire, rarely with 2 lacerate or lobular appendages . Stamens inserted at corolla base or at throat of corolla tube , as many as and opposite corolla lobes to many and in 2 or 3 whorls; staminodes when present alternate with stamens, scaly to petal-like. Ovary superior, 4- or 5-locular, placentation axillary; ovules 1 per locule, anatropous . Style 1, often apically lobed . Fruit a berry or drupe, 1- to many-seeded. Seed coat brown (pale yellow in Pouteria annamensis), hard, shiny, rich in tannin; endosperm usually oily; seed scar lateral and linear to oblong or basal and round .

About 1100 species and 53 genera: pantropical ; 11 genera and 24 species (six endemic) in China.[1]

Genus Pouteria

Trees or shrubs . Branchlets glabrous or pubescent but glabrescent . Leaves usually alternate, not stipulate ; leaf blade papery to leathery, both surfaces usually pubescent when young but glabrescent when mature , sometimes abaxially glabrous and adaxially appressed pubescent, lateral veins conspicuous . Flowers in axillary clusters , sometimes with 2--4 bractlets . Sepals (4 or) 5(or 6), outside pubescent, inside glabrous or sericeous , early deciduous or persistent in fruit. Corolla tubular to campanulate , 4- or 5--8-lobed, appendages absent. Stamens (4 or) 5(--8), inserted in throat of corolla; staminodes less than 5 or 5--8, opposite sepals, lanceolate to subulate , sometimes scalelike to petal-like. Ovary conical , sometimes with cup-shaped disc at base , 5(or 6) -locular, ± villous . Fruit globose, glabrous or tomentose , sometimes setose ; pericarp thin to thick, sometimes very hard when dry. Seed coat shiny, scar oblong to broadly ovate , covering half to nearly whole surface of seed.

About 50 species: tropical areas, mostly in America; two species in China.[2]
