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 Planchonella

Trees or shrubs . Branchlets pubescent but glabrescent . Leaves alternate or opposite, sometimes closely clustered at end of branchlets or with flowers on dwarf shoots . Flowers bisexual or seldom unisexual , solitary or several in axillary clusters , usually bracteate , (4- or) 5(or 6) -merous. Calyx 5-lobed with a short tube , sepals imbricate or twisted. Corolla glabrous , rarely outside pubescent. Stamens 5, inserted in throat and opposite corolla lobes ; staminodes petal-like, alternate to corolla lobes. Disk absent or cup-shaped, ringlike, usually pubescent. Ovary (4- or) 5(or 6) -locular. Fruit a berry, sometimes woody, 1--6-seeded. Seeds compressed ellipsoid ; scar narrowly oblong and lateral .

About 100 species: Australia, Cambodia, India, Indonesia, Japan, Malaysia, New Caledonia, New Guinea, New Zealand, Pakistan, Seychelles, Thailand, Vietnam; S America; two species in China.

Planchonella may not be sufficiently distinct from Pouteria to merit being a separate genus.[2]
