Lin. syst. Didynàmia, Gymnospérmia. Calyx ovate-campanu- 
late, 13-nerved at the base ; upper lip elongated, entire, erect; 
lower lip truncate, almost wanting, or very shortly bidentate; 
throat naked inside. Tube of corolla exserted from the calyx, 
equalling the imbricate bracteas ; limb bilabiate ; the upper lip 
erect, emarginate, flattish: the lower lip spreading, trifid, with 
nearly equal, entire lobes. Stamens 4, erect, ascending, scarcely 
distant, exserted, didynamous : lower ones the longest ; filaments 
glabrous; anthers 2-celled: cells distinct, diverging, or divari- 
cate. Upper lobe of style short ; stigmas minute.—Shrubs with 
quite entire leaves. Flowers aggregate into oblong spikelets, 
Bracteas orbicular, membranous, coloured, loosely-imbricate, 
much longer than the calyxes, equalling the tubes of the corollas.

Cult. The species of this genus are liable to be killed by 
severe frosts if allowed to remain in the open air; but in com- 
mon winters, if planted against a south wall in a dry soil, will 
survive. It is, however, proper to keep a few reserve plants in 
pots, that they may be protected by placing them in a green- 
house or frame. A rich light soil suits them best; and cuttings 
are readily rooted under a hand-glass.
