MENTHACEAE. 315 



flowers in 1-several dense verticillate clusters, these about 1.5-2 

 cm. broad, scarcely equalled by the rounded bracts; bracts tipped 

 with a slender awn, sparsely ciliate on the margins; calyx-lobes 

 purplish tipped, the upper Hp large, arched, tipped with a pair of 

 partly connate short-awned teeth; corolla deep blue, hardly exceed- 

 ing the calyx, the upper lip small, notched, the lower with small

Perennial aromatic herbs or shrubby plants, with 

 rugose veiny mostly crenulate leaves, and rather showy 

 flowers, capitate-glomerate or sometimes more open and 

 paniculate. Calyx bilabiate, mostly deeply cleft on the 

 lower side as if spathaceous. Corolla strongly 2-lipped, 

 the upper lip spreading, 2-lobed or emarginate. Anther- 

 bearing stamens 2; filaments slender, exserted, appar- 

 ently simple and bearing a linear 1-celled anther, or with 

 an articulation showing that the portion above it answers 

 to a filiform connective, the lower end of which some- 

 times projects into a subulate point. Otherwise as in 

 Salvia. {Audibertia Benth.)

\. R. grandiflora (Benth.) Briquet. Herbaceous, very villous

 and interrupted spicate, much bracteate; bracts herbaceous oval,
