description: Phoebe Nees von Esenbeck (1836: 98).
Type:— Phoebe lanceolata (Nees von Esenbeck 1831: 71) Nees von Esenbeck (1836: 109), lectotype designated by Kostermans (1952: 122).
Evergreen shrubs or trees, small to large; perulate buds present or absent; bud scale scars in diffuse clusters or in dense rings along the twigs; indumentum simple. Leaves alternate, evenly spaced along the twigs or somewhat clustered towards the tips of branchlets, entire, penniveined, often glaucous or glaucescent beneath; midrib usually incised on the upper surface, raised beneath; lateral veins slender or stout; tertiary veins scalariform to laxly reticulate; minor veinlets finely reticulate, often conspicuously raised on both surfaces; petioles usually channelled above. Inflorescences terminal, subterminal and axillary, paniculate-cymose, pedunculate, glabrous or variously pubescent. Flowers trimerous, bisexual; hypanthium cupular; tepals 6, usually ovate, apiculate, persistent; stamens 9 in 3 whorls, often pubescent towards base of filaments, those of whorl I and II eglangular, introrse, those of whorl III glandular, extrorse; anthers 4-locular, linear-oblong; staminodes 3, forming whorl IV, fleshy, sagittate; ovary ovoid or globose, sessile; style short; stigma small, capitate or discoid. Fruits fleshy, globose, ovoid or ellipsoid-oblong, enclosed at base by the stiff, erect, somewhat enlarged tepals; fruiting pedicel not or slightly thickened.
