7. C. sparsiflora, Fischer & Meyer. Slender, diffuse or erect, a span to a foot 

 high : upper leaves linear-oblong or linear-lanceolate, seldom tapering at base, 

 merely opposite, or the minute upper floral ones in threes : pedicels solitary, in 

 pairs, or some of the upper in whorls of three, longer or shorter than the flower : 

 calyx-lobes from ovate to deltoid-lanceolate : corolla (mostly violet) strongly de- 

 clined ; the inflated saccate throat very oblique on the tube, about the length of the 

 upper lip : filaments hairy below: gland sessile and projecting forwards, cylindrical- 

 subulate. Ind. Sem. Petersb. (1835)ii. 33. C. parviflora, var. sparsiflora, Benth. 

 in DC. C. solitaria, Kellogg, 1. c. ii. 10. 



Shaded hillsides, &e., from near San Francisco northward. Corolla 4 to 6 lines long : the upper 

 lip and the middle lobe of the lower commonly yellowish and purple-dotted, or paler than the 

 ample and violet lateral lobes. Calyx-tube commonly tinged with purple. 



8. C. parviflora, Dougl. Low, at length diffuse, a span high : leaves mostly 

 oblong or lanceolate ; the upper narrowed at base and entire ; the floral often in 

 threes or fours or even fives : pedicels 1 to 5, mostly longer than the small flowers : 

 calyx-lobes lanceolate, a little shorter than the blue moderately oblique corolla, the 

 oblong gibbous-saccate throat of which is longer than the lips : filaments all gla- 

 brous : gland small and capitate, short-stipitate : stigma 2-cleft. Lindl. Bot. Reg. 

 t. 1802; Hook. Fl. ii. 94, by misprint as C. pauciflora. C. minima, Nutt. in Jour. 

 Acad. Philad. vii. 47. 



Shady moist grounds, from the coast north of San Francisco to the Sierra Nevada ; thence 

 northward to Washington Territory and Lake Superior. Corolla 2 to 4 lines long, rather narrow. 

 Nuttall's C. minima is a depauperate form, early flowering from the seed, with corolla (3 or 4 

 lines long) fully twice the length of the shortish calyx. 



+ -t- Glandular: leaves entire, narrow: lobes of the calyx obtuse, shorter than the 



capsule. 



9. C. Torreyi, Gray. Slender, erect, a span or so high, divergently branched : 

 leaves thickish ; the lowest narrowly spatulate ; the others linear with a tapering 

 base, mainly opposite, or the floral in threes or fours ; all the uppermost of these 

 reduced to minute bracts : pedicels 2 to 7 in a whorl, rather longer than the flowers : 

 corolla deep violet-blue, almost thrice the length of the calyx, moderately declined, 

 the gibbous throat with the tube about the length of the lower lip : filaments gla- 

 brous : gland sessile, subulate. Proc. Am. Acad. vii. 378. 



Common in the higher parts of the Sierra Nevada, from Mariposa Co. to Nevada Co., Torrey, 

 Bolander, Watson, &c. Somewhat viscid, beset with minute dark glands. Corolla 3 or 4 lines 

 long ; the plaits forming the margins of the sac of the lower lip terminating below in a spur-like 



E rejection. Seeds oblong, more terete than usual, and large for the size of the capsule, a line 

 mg. 



7. TONELLA, Nutt. 



Corolla obscurely bilabiate ; the 5 more or less unequal lobes somewhat rotately 

 spreading, the lower not complicate nor enclosing the soon ascending stamens and 

 style ; the tube slightly gibbous posteriorly. Ovules and seeds from one to four 

 in each cell. Cauline leaves mainly ternately divided or 3-parted. Otherwise as 

 in Collinsia. Xutt. ex Benth. in DC. Prodr. x. 593 ; Gray, Proc. Am. Acad. vii. 

 378, & xi. 92. 



1. T. COllinsioides, Xutt, 1. c. Slender annual, diffusely branched from the 

 base, nearly glabrous : branches filiform, a span to a foot long : radical and lowest 

 cauline leaves ovate or roundish, somewhat lobed, crenate or entire (a quarter to 

 half an inch long), on slender petioles ; the others shorter-petioled or sessile, 3-parted 

 or divided into oblong or lanceolate divisions or leaflets ; the floral ones sometimes 

 in whorls of three, and the uppermost simple, and shorter than the slender filiform 

 pedicels ; these solitary, or in pairs, or sometimes 3 in a whorl : flowers minute, at
