Rhysotoechia Radlk.

Trees, small to medium sized, or shrubs. Branchlets terete, rough to smooth. Indumentum if present mostly of simple, appressed hairs. Leaves (im)paripinnate; petiole and rachis terete, slightly winged or not, petiole pulvinate; petiolules pulvinate, sometimes absent. Leaflets opposite to alternate, lower surface with domed cells; base symmetric to slightly oblique; margin entire; domatia absent. Inflorescences axillary, subterminal or ramiflorous, paniculate or thyrsoid; bracts and bracteoles usually not persistent in fruit. Flowers regular, seemingly bisexual. Sepals 5, subpersistent in fruit, outer 2 slightly to distinctly smaller than inner 3, inner ones with a petaloid margin. Petals 5, (distinctly) clawed; scales absent to well developed, crest absent. Disc entire, slightly lobed, glabrous. Stamens 8 (or 7); filaments especially towards the base pilose or velutinous; anthers often with a few hairs. Ovary 3-(or 2-)celled, sericeous; style usually glabrous, elongating in fruit. Ovules 1 per cell. Fruits obcordate to reniform, with one to all lobes developing, loculicidal, outside rugose to ribbed, often laxly hairy, inside (densely) papillose, stipe absent to very distinct. Seeds obovoid to orbicular, covered by a cup-shaped arillode (or a sarcotesta), except at the apex; hilum round; pseudohilum round to reniform.
