_ high, square, smooth, purplish. Branches opposite, square, 
with the sides deeply channelled. Leaves opposite on 
channelled footstalks, three parted : leaflets ovate-lanceo- 
late, coarsely serrate: serratures unequal, obtuse, some 
of them denticulate: Flowers blue, in leafy corymbs, ter- 
minal, and axillary, on peduncles longer than the petioles. 
— Calyx subcampanulate; half five-cleft : segments acute, 
spreading, cerulescent. Corolla minute, ringent, blue: 
Stamens 2 : filaments short : anthers white, didymous. 
ermens apparently united to near the apex. Style longer 
than stamens, blue: Stigma bifid: lower segment, revo- 
lute. When ripe, the germen separates into four gibbous 
Seeds, rough on the convex side. The whole plant 1s very 
t. AmETHysTEA appears to us to be a connecting: 
link between the natural orders of Labiate and Vitices.
