The genus Hyptis, together with the small allied genera, 
Peltodon, Marsypianthes, and Eriope, consists entirely of Ame- 
rican species, and is readily known among Ocimoidee by the 
pouch-shaped hanging lower division of the corolla, attached by 
so narrow a base that it appears often almost articulate. It is 
one of the most extensive in the Order, as there are above 220 
species known ; most of them natives of the lower mountainous 
regions of South America, and a few of them exceedingly com- 
mon wherever cultivation has commenced under the tropics in 
the new world and even in the old world, where they have pro- 
bably been introduced by man. There is a very great diversity 
in habit, but little in structure of the flower, in the different 
species which have been distributed into nineteen sections 
founded chiefly on inflorescence. The H. verticillata belongs 
to the fifteenth section Minthidium, consisting of herbs or under- 
shrubs, with the flower-cymes sessile or nearly so, many-flow- 
ered, and condensed into verticillasters as in the majority of 
Latiate, the calyx regular, the corolla scarcely protruding from 
it, and the bracts inconspicuous. The species have thus 
very much the appearance of Menthe, in everything but the 
corolla and.stamens. Bentham.
