Names
KOHAUTIA Cham. & Schlecht. [family RUBIACEAE], in Linnaea 4: 156 (1829); Bremek. in Verh. K. Nederl. Akad. Wet., Afd. Natuurk., ser. 2, 48 (2): 56 (1952)
Information
Annual or perennial herbs or rarely subshrubs, mostly erect, often much branched. Leaves sessile, opposite, nearly always linear and mostly 1-nerved, less often penninerved or 3–5-nerved from the base; stipules with 2-several fimbriae or rarely reduced to a simple lobe. Flowers small or medium-sized, never heterostylous, in panicles, corymbs, occasionally in heads, more rarely in pairs, triads or even solitary. Calyx-lobes 4 (rarely 5), small, equal, subulate to ovate-triangular or triangular. Corolla-tube narrowly cylindrical; lobes 4 (rarely 5); throat glabrous or pilose inside. Stamens always included in the upper swollen part of the corolla-tube or only the anther-tips exserted. Ovary 2-locular; ovules numerous, immersed in fleshy peltate placentas; style always included, the stigma not divided, cylindrical, or divided into 2 filiform lobes mostly with the tips well below the base of the anthers or just reaching them. Capsule globose or ellipsoid, scarcely beaked, loculicidally splitting at the apex. Seeds numerous, angular, mostly not becoming viscid when moistened, somewhat alveolate.
Range
A genus of about 60 species occurring throughout Africa and also in Madagascar and parts of tropical Asia.
Notes
The structure of the flowers supports Bremekamp’s claim that this is undoubtedly a genus distinct from Oldenlandia; it is also fairly easy with practice to separate them by habit alone. He divides the genus into subgen. Pachystigma, with two series, Barbatae and Imberbae, and subgen. Kohautia (Eukohautia), with two series Diurnae and Kohautia (Noctiflorae). The classification is illustrated in the form of a key on p. 230.
