Cremaspora Benth.

Genus

Angiosperms > Gentianales > Rubiaceae

Characteristics

Shrubs, small trees or sometimes lianes or with subscandent branches; stems and foliage almost glabrous to densely hairy; branches appearing supra-axillary and often supported by rounded leaves very different from the main foliage. Leaves opposite, shortly petiolate, mostly thinly coriaceous, mostly oblong-elliptic; stipules keeled, acuminate, soon deciduous. Flowers sweetly scented, rather small in sessile mostly dense axillary clusters; bracts and bracteoles triangular-acuminate, not forming cupules. Calyx-tube ovoid; limb campanulate with 5 triangular to lanceolate teeth. Corolla white, cylindrical or very narrowly funnel-shaped, glabrescent or pubescent outside, glabrous to pilose at the throat; lobes 5, narrowly oblong, ± obtuse or acute, strictly contorted, pubescent outside. Stamens 5, inserted at the mouth of the tube; filaments very short; anthers buff, dorsifixed, linear, apiculate, ± bifid at the base, fully exserted. Disc shallowly bowl-shaped, becoming more cylindrical in fruit. Ovary 2-locular, with a single ovule in each locule, pendulous from the apex; style green, filiform, exserted, hairy save at extreme base, the apical 1 mm. divisible into 2 lobes which do not spread and bear the stigmatic surface on their inner faces. Fruit ovoid, indehiscent, leathery-walled, 2-locular, (1–)2-seeded. Seeds half-ovoid, compressed, rugulose; testa characteristically finely transversely wrinkled-striate; albumen horny, not ruminate; embryo small with inferior radicle; placenta elongated, lying along whole side of seed.
