ORDER LXIIL LABIATEA!.—Juss. 
Perianth double. Calyx inferior, persistent, tubular, either five 
toothed with the fifth tooth superior and next the axis, or ten 
toothed regular or irregular, bi-labiate. Corolla monopetalous, 
hypogynous, bilabiate, deciduous, the upper lip entire, or bifid, 
the lower larger, three lobed. Stamens four, didynamous, inserted 
upon the corolla, and alternate with its lobes, the two upper 
sometimes wanting. Anthers two celled, sometimes apparently two 
celled, in consequence of the cells being united at the apex, or the 
cells are separated by a bifurcation of the connectivum. Ovary 
deeply four lobed, seated in a fleshy hypogynous disk, each lobe con- 
taining an erect ovule. Style single, bifid, arising from the base of 
the lobes of the ovary. Stigma bifid. fruit one to four nuts, 
enclosed within the persistent calyx. Seeds erect, with little or no 
albumen. Lmbryo erect, deeply cleft. Cotyledons straight, or curved 
at the apex. Radicle straight, or slightly curved.—Herbaceous plants 
or undershrubs. Stem four angled, with opposite branches. Leaves 
opposite, divided, or simple, without stipules, furnished with glands, 
secreting a volatile oil. Flowers in opposite nearly sessile axillary 
cymes, resembling whorls, sometimes solitary, or as if capitate.
