similar to the bracts or narrow. Calyx small, deeply 5-lobed; segments 
linear-lanceolate. Corolla small, blueish or white; limb 2-lipped, upper lip 
emarginate shorter than the lower 3-lobed lip. Stamens 2; anthers 2- 
celled, cells parallel subequal, or more often superposed, lower cell maticou 
or white-tailed. Ovary 4-ovulate; style filiform, minutely bifid. Capen 
ovoid or oblong, shortly stalked; after dehiscence the placentæ wit M 
retinacula rise elastically from the base of the capsule, scattering tne 
seeds. Seeds 4, compressed, orbicular, glabrous, verrucose, sometimes 
minutely, sometimes very strongly, so that the seed is concentrically rugos 
or subcristate.—Species 20, mostly Asiatic, a few Tropical African. 
I am unable to make sections of this genus; the species are described in order of 
their size, beginning with the largest.
