Hymenodictyon parvifolium Oliv. is a small rubiaceous African tree and is one of some 24 species in the genus, with a tropical African and Asian distribution. This species grows as a small tree to some 5 metres tall, or sometimes a liane or scrambler to 10.5 m, and is found in low-altitude woodland 250 – 1110 mLeaves are 3.5 x 1.5 cm, obovate to oblanceolate with acute apex and decurrent base, and minutely puberulous on veins of lower surface. Flowers are terminal in thyrsoid panicles, at ends of short lateral shoots, and are very fragrant. Calyx small and much shorter than corolla, glabrous to scabrid-pubescent; lobes up to 2.5 mm long, lanceolate. Corolla white, greenish-white or yellow, with touches of red in bud; glabrous or puberulous; tube cylindrical below, bell-shaped or campanulate above; lobes 5–6, ovate, ciliolate; style long, strongly protruding from the corolla. The tree produces ellipsoid, reddish-grey-brown capsules of about 2.5 × 1 cm, covered in prominent lenticels, splitting from the apex into 2 valves, which in turn may split for a short distance. Its seeds are straw-coloured, 1.6 × 1.0 cm, and somewhat elliptic, compressed and winged, the wing notched at the hilar end, and the seed coat strongly reticulate and slightly shiny
