LABIATZ. 
tubular, with a straight or oblique mouth; teeth 5, nearly 
equal, acute, or subulately awned. Corolla with the tube 
about equal in length to the calyx, 3-4-cleft, sub-bilabiate ; the 
4 upper lobes quite entire, flat, all distinct, or the upper 2 are 
joined: lower one abruptly deflexed at the time of florescence, 
saccate, contracted, and subarticulated at the base. Stamens 
4, declinate ; filaments free, toothless ; anthers ovate-reniform, 
with confluent cells. Style about equally bifid at top; lobes 
subulate; stigmas for the most part terminal, minute on the 
inside of the lobes of the style, rarely altogether stigmatiferous ; 
disk equal, the lower side generally furnished with an obtuse 
tooth. Achenia ovoid, oblong, or compressed, smooth, rarely 
wrinkled, and in some species margined by a flat wing, but 
never navieular.—Herbs or subshrubs. Inflorescence and habit 
very variable. ‘Looking to the large number of species, and 
to the great variety in their habit, it would seem at first more 
convenient to divide this group into a number of genera; but 
on examination the essential characters have proved to be so 
nearly the same in all, the difference consisting chiefly in the 
uncertain characters of inflorescence, that I have preferred con- 
sidering the different groups into which they have been distri- 
buted as mere sections." Benth. lab, p. 65.
