554 SCROPHULARIACE^E. Collinsia. 



++ Filaments and interior of the throat of the corolla somewhat bearded: upper lip of 

 the latter crestless : calyx-lobes broadish, obtuse. 



3. C. bartsiaefolia, Benth. Puberulent and somewhat glandular, rarely hairy 

 above : stem strict and simple or loosely branched*:- leaves from ovate-oblong to 

 linear : flower-whorls 2 to 5, rarely only one : calyx either naked or villous : upper 

 lip of the corolla about the length of the curved gibbous throat ; the lower narrow 

 at the base, its lateral lobes emarginate or obcordate : gland sessile and elongated, 

 porrect. DC. Prodr. x. 318. C. bicolor, var., Benth. PI. Hartw. 328, no. 1884. 

 C. hirsuta, Kellogg, 1. c. 110, fig. 34, hairy form. 



Common throughout the central and western parts of the State to the foot-hills of the Sierra 

 Nevada, mostly in sandy soil. Corolla from half to two thirds of an inch long, purplish, pale 

 violet, or whitish : upper lip with a low transverse callosity at the origin of the limb, bordering 

 a small hooded depression. 



4. C. corymbosa, Herder. Minutely puberulent or nearly glabrous, branched 

 from the base and diffuse or decumbent, tufted : leaves oblong or oval, very obtuse, 

 rather fleshy : flowers mainly in a single terminal and leafy-bracted capitate cluster : 

 upper lip of the straightish corolla very short, its limb (spreading above the trans- 

 verse callosity) almost obsolete ; lobes of the elongated lower lip entire : gland 

 small, oblong, flattish, short-stipitate. Ind. Sem. Petersb. 1867, & Gartenfl. 1868, 

 35, t. 568 ; Gray, Proc. Am. Acad. vii. 378. 



Coast of the northern part of the State ; on the beach at Fort Bragg, Humboldt Co., Bolander. 

 Described from cultivated specimens, the seed said to come from Mexico, 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. 



++ -M- Filaments and interior of the corolla glabrous : upper lip of the latter promi- 

 nently crested. 



5. C. G-reenei, Gray. Small and slender, glandular-puberulent : leaves oblong- 

 linear and tapering to the base, rather coarsely and sparsely dentate : flowers few 

 (2 to 6) in the clusters, on pedicels sometimes as long as the calyx : lobes of the 

 latter acutish : upper lip of the violet purple corolla much shorter than the oblong 

 throat, about half the length of the lower, crested above the gorge and under the 

 origin of the limb with a pair of conspicuous callous teeth on each side, which are 

 connected by a less elevated transverse ridge; the lateral lobes of the lower lip 

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



Crevices of rocks, Lake Co., E. L. Greene. Corolla 5 lines long : the callosity of the upper 

 lip, which is obvious in some other species, is in this developed into a projecting 2-toothed 

 crest. 



* * Flowers slender-pedicelled, solitary or umlellate-whorled. 



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

 roundish and more or less toothed: lobes of tJie calyx acute, longer than the capsule. 



6. C. grandiflora, Dougl. A span to a foot or so in height : upper leaves from 

 spatulate-oblong to linear-lanceolate ; the floral mostly in whorls of 3 to 7 : pedicels 

 at least as many in the whorls, not longer than the flowers : calyx-lobes tapering 

 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 upper lip ; the larger lower lip deep 

 bright blue or violet : filaments glabrous : gland sessile and capitate. Lindl. Bot. 

 Eeg. t. 1107. 



Shady hillsides, Mendocino Co. (Bolander, Kellogg] ; thence north to Washington Territory. 

 Corolla about half an inch long ; the lobes a little undulate or merely emarginate : a pair of 

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

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

 the name, this is by no means the largest-flowered species, but the blossoms are numerous 

 and showy.
