I. HEBENSTREITIA, Linn. 
Calyz membranous or hyaline, spathaceous, the apex posticous, 
entire or emarginate. Coro/la-tube slender, divided in front down to 
or below the middle, expanded behind into a flat or concave 4-lobed 
limb ; lobes subequal or the intermediate pair longer or deeply connate, 
occasionally with a fifth minute lobe in the fissure of the tube. 
Stamens 4, didynamous, affixed to the margins of the divided tube 
below the lobes; filaments short ; anthers oblong or linear. Ovary 
2-celled; style entire. Fruit oblong, ovate or broad, subterete or 
compressed, rarely separating spontaneously into distinct cocci, both 
cells perfect or one abortive ; pericarp equally indurated round the 
cells or variously dilated and corky, with a pair of spurious cells at 
their adjacent margins. Seeds oblong, cylindrical. 
Shrubs, undershrubs or annual herbs ; leaves alternate or the lower opposite, 
often narrow, entire or often toothed, sometimes short and broad; spikes 
terminal, often dense, short or elongate; flowers sessile, white, yellow or rose; 
bracts broud or narrow, or the lower somewhat leaf-like, imbricate or lax, 
exceeding the calyx. : 
Species 30 South African, one of which extends into Tropical Africa as 
far as the mountains of Abyssinia, with one other only known from Tropical 
Africa.
