Type: Eureiandra formosa Hook.f., F. Welwitsch 807 (LISU (holotype), G-DC, K, PRE (isotypes)), Angola, Cuanza Norte, Golungo Alto.

Perennial or rarely annual climber with herbaceous to more or less woody shoots, tuberous rootstocks, and dioecious sex system. The leaves are simple, petiolate, the blade entire or palmately 3-5-lobed. The tendrils are simple. The flowers are medium-sized to large, often on leafless shoots. Male flowers are produced in short, pedunculate fascicles or solitary, the female flowers are solitary. The receptacle-tube is narrowly campanulate and apically dilated, the five sepals are lanceolate, acute, often acuminate, finely pubescent. The five petals are cream-coloured to orange-yellow (rarely white), free, obovate, rounded, apiculate, to 3.5 cm long. The three or five stamens are inserted about halfway up the tube on free filaments or two pairs of fused filaments plus one free filament. The anthers are all monothecous or two bithecous and one monothecous. The thecae are triplicate, glabrous or minutely to conspicuously hairy and contain tricolporate, reticulate, medium-sized pollen (polar axis 54-79 µm, equatorial axis 63-79 µm, (Khunwasi 1998)). The ovary is ellipsoid-cylindrical, ± rostrate, with many, horizontal ovules. The stigma is trilobed. The fleshy fruit is ellipsoid or cylindrical, rostrate, up to 13 cm long and 8 cm in diameter, indehiscent, ripening orange to red. The seeds are ovate to globose with blackish, smooth or fibrillose testa.

The eight species grow in woodland and wooded grassland, and in coastal forests of tropical and subtropical Africa, one species, E. balfourii, is endemic to Socotra.

Phylogenetically, Eureiandra is sister to Bambekea in the tribe Coniandreae (Schaefer et al., 2009; Schaefer & Renner 2011).
