bright green and subglabrous above, glaucous and inconspicuously 
erey-hispid beneath, blunt with a faint mucro, 4—6 lines long, the ter- 
minal one stalked, the side ones alternate. Racemes laxly 6-20- 
flowered on peduncles 3-6 lines long, finally 12-18 lines long. Pe- 
dicels very short, the lower cernuous. Calyx } in. deep, thinly grey- 
hispid, the linear-setaceous teeth reaching down nearly to the base. 
Corolla purplish-red, half as long again as the calyx, the standard § ™.
