what obovate, very obtuse; sepals glandularvillous (as they 
are, less conspicuously, in Douglas’s specimens) ; corolla strong- 
ly bearded, especially at the summit of the lobes, with long and 
glandular hairs. The expression “labio superiore villoso” does 
not adequately express it.

(segmentis lanceolato-ovatis) pedicellisque glanduloso-puberis ; 
corolla (purpurea ? extus pruinoso-puberula) longé cylindrica,

Stems or simple branches slender, one or two feet long, leafy to 
the inflorescence, the leaves about the length of the internodes. 
__ Flowers in a virgate panicle. Tube of the corolla an inch long,

lobes and upper lip only three lines long. Fertile filaments 
glabrous except at their base, where they are sparsely hirsute ;
