846 LABIATA. 
mouth equal or drawn out obliquely above or beneath, 8-10- 
toothed. Corolla with an inclosed tube, which is annulate, or naked 
inside, and a bilabiate limb ; upper lip concave, erect, entire, 
rarely emarginate, very hairy outside ; lower lip longer, spread- 
ing, trifid, the middle segment the largest. Stamens 4, didyna- 
mous, ascending, the lower ones the longest ; filaments naked at 
the base; anthers approximate by pairs under the upper lip, 
sub-bilocular : cells divaricate, confluent. Upper lobe of style 
very short, lower one subulate and stigmatiferous towards the 
apex. Achenia dry, triquetrous, obtuse at apex.—Herbs or 
under shrubs. Leaves quite entire or usually toothed; floral 
ones nearly similar. Whorls sometimes few-flowered and some- 
times densely many-flowered. Corollas usually white, rarely pur- 
plish.—Scarcely differing from Balldta, except in the unequally 
lobed stigma, but the calyx, corolla, and the general habit mark 
it out as a good genus.
