2-lipped corolla with inflated throat (upper lip erect and entire, lower 
spreading, 3-cleft, middle lobe smallest and notched), and 2 ascending 
exserted stamens. 
1. B. hirsuta Benth. Hairy throughout: leaves long-petioled, ovate, pointed, 
rounded or heart-shaped at base: lower floral ones similar, uppermost and bracts

oblique 5-toothed calyx, 2-lipped corolla (upper lip nearly erect, 2-lobed ; 
lower somewhat spreading, 3-cleft, middle lobe crenate), 4 exserted sta- 
mens with inner pair declined and outer shorter pair ascending (so that 
the pairs cross), and nearly parallel anther-cells. 
1. L. nepetoides Benth. Stem stout, 6 to 18 dm. high, smooth or nearly so,

anther-cells. 
1, C. micrantha Gray. Puberulent: leaves slender-petioled, coarsely crenate-den-
