Vangueriopsis Robyns ex R.D.Good

Genus

Angiosperms > Gentianales > Rubiaceae

Characteristics

Shrubs or small trees with mostly stiff thick branches. Leaves opposite, somewhat coriaceous, hairy or velvety tomentose; stipules thick, triangular, ± joined into a sheath at the base, long-caudate at apex. Flowers large and conspicuous, ± thick, in opposite simple to much-branched many-flowered axillary cymes; bracts fairly conspicuous. Calyx-lobes erect, triangular to linear-lanceolate or linear-oblong. Buds elongate-lanceolate, beaked. Corolla-tube cylindrical, 2/3–1/8 the length of the linear-lanceolate lobes, with a ring of deflexed hairs or glabrous within save at base; throat glabrous. Stamens inserted at the throat; anthers exserted, linear. Ovary 2-locular (5-locular in V. gossweileri), each locule with a solitary pendulous ovule; style slender, long-exserted; stigmatic club cylindrical. Fruit fairly large, didymous when 2 pyrenes developed but unilateral and oblique when 1 is aborted, smooth or irregularly ribbed; presumably ± globose in V. gossweileri.
