Calyx inferior, usually deeply 5-fid, ^-i in. long. Corolla asym- 

 metrical; limb 5-lobed, two-lipped, sometimes a little irregular, 

 sometimes the 3-lobed lip much the longer. Stamens 2, on the 

 corolla-tube, rudiments of two or three others often present ; anther- 

 cells early confluent; pollen globose or in a few species ellipsoid, 

 very minute. Ovari/ cylindric ; placentas much intruded, bearing 

 the numerous ovules only on their margins ; style linear-cylmdric, 

 persistent; stigma subcapitate. Capsule linear, 1-3^ m. long, 

 splitting into 2 spirally twisted valves which separate from the 

 placentas. Seeds very small, ellipsoid or oblong, brown. 



Herbs, in the Cape species usually nearly or quite stemless, with many-celled, 

 often gland-tipped hairs; peduncles carrying many flowers in •f^'^^/'y™".^' ('^

Section 1. Unifoliatje.— Leaf 1, spread flat on the ground, known in many 

 species (presumed in the others of this series) to be one of the cotyledons; ttic 

 other cotyledon disappears or rarely is persistent and much smaller ; the foliar 

 cotyledon grows out to a leaf perhaps 3 in. wide in the first season, but more than 

 2 ft. wide in the next. (See Crocker, Journ. Linn. Soc. v. 66.)
