C. Greenei, Gray. Slender and smaller, erect, glandular-puberulent : leaves oblong- 

 linear, tapering to base, sparsely and coarsely dentate : flowers 2 to 6 in the clusters, on 

 pedicels sometimes as long as the calyx : corolla violet-purple, 5 or 6 lines long ; its upper

* * Flowers slender-pedicelled, umbelliform-verticillate, or sometimes solitary. 



-1 Calyx-lobes acute, from lanceolate or even ovate to subulate, usually surpassing the capsule : 

 plants glabrous, or the stems and pedicels puberulent, not glandular or viscid: leaves in the same 

 species either somewhat serrate or entire : seeds about 4, smooth or nearly so. 



*-+ Eastern species : showy corolla half inch long, with very gibbous throat much shorter than the 

 limb : upper filaments more or less bearded below. 



C. Verna, Nutt. 1. c. Stem 6 to 20 inches high : leaves ovate or oblong, or the lowest 

 rounded and slender-petioled, and the upper ovate-lanceolate and partly clasping ; the 

 upper floral reduced to subulate-linear bracts : whorls about 6-flowered : pedicels filiform, 

 longer than the flowers : throat of the corolla equalling the calyx-lobes ; the ample lower 

 lip bright blue ; the upper white or purplish ; lobes barely emarginate : gland subulate,

C. grandiflora, Dougl. A span to a foot high : leaves thickish ; the lowest roundish 

 and petioled ; upper from oblong to linear and sessile ; the floral in whorls of 3 to 7 : pedi- 

 cels in whorls of 3 to 9, about the length of the flower: calyx-lobes lanceolate gradually 

 subulate-attenuate to a very acute point: corolla half to two-thirds inch long, white or 

 purple with lower lip deep blue or violet ; its very saccate throat as broad as long, almost 

 or quite transverse with the tube, as long as the recurving (internally 2-callous) upper lip ; 

 lobes of the larger lower lip merely refuse or emarginate : filaments glabrous : gland ses- 

 sile and capitate: seeds roundish, smooth. Lindl. Bot. Keg. t. 1107 ; Gray, I.e. Shady 

 hills, &c., from Mcndocino Co. California to Brit. Columbia along the coast. 



Var. pusilla. Small form, a span or more high : corolla only 4 or 5 lines long, more 

 blue or violet throughout. Plumas Co. California to Brit. Columbia. 



C. sparsiflora, Fisch. & Meyer. More slender: upper leaves all lanceolate and 

 linear, all opposite, or the uppermost small bracts in threes : pedicels solitary or some of 

 the upper 2 or 3 in a whorl, sometimes longer than the flower : calyx-lobes from ovate to 

 deltoid-lanceolate, acute : corolla 4 to 8 lines long, violet ; the saccate throat very oblique 

 but not transverse ; upper lip hardly shorter than the lower : filaments hirsute below : gland 

 sessile, elongated-subulate : seeds meniscoidal, acute-margined, obscurely reticulated. Ind.
