** System of Physiological Botany,” two vols. 8vo. London, 1816.) 
Benth. lab. p. 409. E 
Lin. syst. Didndria, Monogynia. Calyx tubular, about 13- 
nerved, striated, with an equal or oblique mouth, and 5 nearly 
equal teeth; throat naked, or villous inside. Corolla with an 
exserted tube, and a bilabiate limb: upper lip erect, emarginate, 
flat: lower lip spreading, trifid, with flat nearly equal lobes. 
Two lower stamens fertile, ascending, without any vestiges of 
the upper ones; anthers 2-celled, with a thick connective and 
distinct divaricate cells. Lobes of style nearly equal, or the 
lower one is longest and flattened, involving the base of the 
upper one.—Herbs, sub-shrubs, or shrubs. Whorls sometimes 
axillary and sometimes approximating into terminal spikes. Co- 
rollas usually scarlet. This genus differs from Melissa in the 
more regular calyx, and the abortion of the 2 upper stamens, 
which latter character alone separates it from Gardoquia.
