1. Homalium sect. Homalium = Racoubea Aubl., Hist. Pl. Guiane 1: 589, tab. 236. 1775. �� Homalium sect. Racoubea (Aubl.) C.B. Clarke in Hooker, Fl. Brit. India 2: 597. 1879. Typus: Homalium guianense (Aubl.) Oken. (�� Racoubea guianensis Aubl.). = Napimoga Aubl., Hist. Pl. Guiane 1: 592, tab. 237. 1775. Typus: Napimoga guianensis Aubl. Stipules axillary, free. Inflorescences racemose (to spicate) or paniculate; bracts small or narrow, usually persistent, bracteoles small, usually borne high on pedicel. Flowers pedicellate to subsessile (in part sessile), with pedicels articulated, 5-7- merous. Sepals ovate (to somewhat oblong or oblong-lanceolate), often moderately accrescent; calyx tube funnelform, in fruit to nearly hemispherical or broadly turbinate; sepal glands quite large, rounded to oblong-elliptic. Petals ovate to elliptical (to somewhat oblong, in H. fulviflorum Sleumer broadly spatulate), similar to sepals in size or longer, usually spreading at anthesis, often moderately accrescent; sepals and petals not ciliate or minutely ciliate. Stamens (2-)3-7(-8) per petal, inserted between glands; anthers dorsifixed, broadly oblongelliptical with oblong-elliptical locules and a large connective, the slits of dehiscence nearly parallel. Upper surface of ovary conical (to nearly flat) in flower, conical (sometimes very prominently) in fruit; styles fused basally into a short column (less often free to near base, or fused for most of length), the branches 3-4(-5). Locule of fruit ovoid to ellipsoid, apically conical, pubescent; seeds where known 1-2 per fruit, often ellipsoid, mostly filling the locule (sometimes several immature seeds present, possibly not maturing). Distribution. ��� Africa, Central and South America. Species included. ��� Homalium abdessammadii, H. angustifolium Sm., H. fulviflorum, H. guianense, H. racemosum, H. senarium Mo��. & Sess�� ex DC.
