Coaat of the nortliern part of the State ; on the beach nt Fort Hrngg, Humboldt Oo., Bolnndcr. 

 Described from cultivated specimens, the eeed said to come from Me.xico, which is most unlikely. 

 Corolla three fourths of an inch long ; lower lip white or somewhat cream-colored, the very short 

 upper one blue or bluish.

 small : gland small and sessile. — Proc. Am. Acad. x. 75. 



Crevices of rocks, bake Co., E. L. Orcevc. Corolla 5 linos long : the callosity of the ujiper 

 li|>, whicii is obvious in some oilier species, is in this developed into a projecting '2-loolhid 

 crest. 



* * Flowers slender-pedicelled, solitary or lanbellate-tvhorled. 



+■ Glabrous or minutely more or less puberulent : at least the lowest leaves broadish or

 from a broad base to a slender subulate point : corolla strongly declined ; the very 

 saccate throat broader than long, and with its axis almost transverse with that of 

 the tube, about the length of the pale or white upi)er lip ; the larger lower lip deep

Shady liillsides, Mendocino Co. (Bolnndcr, Kelhnig) ; thence north to Washington Tenitory. 

 Corolla about half an in('h long ; the lobes a little undulate or merely emarginate : a pair of 

 strong and hood-like callosities on the upper lip. Nearest C. viulacea of Arkansas, which has 

 obcordate-cleft lateral lobes to the corolla and much less acute calyx-lobes. Notwithstanding 

 the name, this is iiy no means the largesl-ilowered species, but the blossoms are numerous 

 and showy.
