Small, medium-sized or large trees; bole frequently twisted; buttresses low, rounded, similar to those of Vatica. Crown hemispherical, rather small. Bark surface greyish, at first smooth, hoop marked; becoming irregularly, frequently shaggy, flaky, leaving a distinct scroll-marked surface below. Stipules fugaceous. Leaves oblong to ovate-lanceolate, coriaceous, margin revolute, undersurface lepidote; nerves curved, unraised above, hardly so beneath, bifurcating towards the margin and anastomosing to form a looped intramarginal nerve, with shorter indistinct intermediate nerves similarly bifurcating; tertiary nerves reticulate, indistinct; midrib sunken above; petiole comparatively short, not geniculate. Calyx lobes imbricate in flower; 2 obtuse outer lobes somewhat larger than 3 acute inner lobes. Petals free, broad, elliptic-oblong, cream or pink. Stamens 15, subequal, in 3 whorls, hence pairs alternating with single stamens; filaments short, deltoid, connate at base; anthers narrowly oblong, latrorse, with 4 pollen sacs, the inner 2 shorter than the outer 2, setose along the lateral margins; appendage to connective short, slender. Ovary free from calyx, ± globose; stylopodium indistinct; style filiform, slender, many times longer than ovary, shortly pubescent towards base; stigma small, trifid, slightly broader than style. Fruit as in sect. Sunaptea of Vatica; calyx free from nut, with distinct filiform style remnant. er
Main canopy trees of dry acid soils, especially on coastal hills, but also on rentzinas over limestone and mountain ridges inland to 1500 m; sometimes semi-gregarious.
