Grevea Baill.

Small trees or shrubs. Leaves opposite or subopposite. Young foliage buds in leaf-axils and at node-scars with multicellular hairs, appearing as a fringe to the scars. Male flowers in axillary inflorescences and ♀ flowers terminal, solitary; bracts very small or obsolete. Male flowers: calyx-tube cupular, subentire, exceeding the disk; petals 3; stamens (2–)3, with introrse anthers; rudimentary ovary minute or ± absent. Female flowers: calyx-tube smooth and striate or tuberculate, with (3–)4 inconspicuous incurved lobes; petals 4(?–5); staminodes 4; style thick, 2-lobed at the apex; each lobe covered entirely by the stigmatic surface on its inner face so that the surface is continuous, but only on the margins and outer areas of the outer faces (the stigmas thus appearing to be 2), ± ovoid with a part of each style-lobe left in the middle of the outer faces; each lobe may again be bilobulate or (fide Capuron) the style may be bifid, each branch bearing a bilobulate stigma or even the style divided to the base and the stigmatic zones extending towards the base on the inner side of the branches. Ovary completely 2-locular or sometimes 1-locular, the 2 parietal placentas meeting at the centre but not completely joining. Ovules 2–9(–12 fide Capuron) on each placenta, pendulous, 1–2-seriate. Fruit indehiscent, with coriaceous to crustaceous pericarp, crowned by the calyx-limb, the placentas expanding to form 1–2 masses (according to whether the ovary is 1–2-locular), but eventually the mass of seeds embedded in the fleshy endocarp forms a single mass in a unilocular fruit. Seeds ovoid or globose, 2–9(?–12) to each placenta; testa consisting of a single layer of polygonal cells, membranous, obscurely finely reticular; endosperm abundant, horny.
