solitary in the lower forks : calyx-lobes more subulate from a broad base. Proc. 

 Am. Acad. viii. 259. C. tinctoria, Kellogg in Proc. Calif. Acad. iii. 17, t. 2. 



Sierra Nevada, mainly in the eastern portion ; thence to British Columbia and the northern 

 regions east of the Rocky Mountains. The var. subulata, which is peculiar in aspect, and may be 

 distinct, on the eastern borders of the State, from Nevada Co. to Oregon, and in Nevada. 



3. C. tenella, Gray. Diffusely branched, slender, 3 to 5 inches high : leaves 

 narrowly linear, with a tapering base (sometimes an inch and a half long) : flowers 

 scattered, solitary in all the forks, almost sessile : calyx-lobes broadly triangular and 

 acute, shorter than the tube : corolla narrow, purplish, 3 or 4 lines long. Proc. 

 Am. Acad. viii. 259. 



Sierra Nevada ; south of Yosemite Valley, at 8,000 feet (Gray) ; Nevada and Utah, Watson. 

 -t- +- Calyx-tube rounded at base and very short : many lower leaves opposite. 



4. C. gracilis, Dougl. A span or two in height, in age corymbosely much 

 branched : the flowers at length somewhat scattered : leaves lanceolate or linear, or 

 the lowest oval or obovate (an inch or less long) : corolla rose-purple, turning bluish, 

 less than half an inch long, narrow ; the tube hardly exceeding the linear calyx- 

 lobes ; the oval lobes less than a line long. Gilia gracilis, Hook. Bot. Mag. 

 t. 2924. 



Hills, not rare through the State ; extending to British Columbia and to the Rocky Moun- 

 tains ; also in Chili. The seeds are mucilaginous, but want the spiral threads of all the other 

 species. 



* * Leaves deeply cleft or compound, the lower petioled : stems loosely branched. 



5. C. gilioides, Benth. A span to 3 feet high : lower leaves simply pinnately 

 parted into few or several linear lateral lobes, or the larger terminal lobe oblong 

 and toothed : upper leaves 3 5 -divided : flowers scattered or somewhat clustered : 

 lobes of the nearly 5-parted calyx linear-subulate, its base rounded: corolla pink 

 or purplish, its slender tube about half an inch long, twice or thrice the length of 

 the calyx : stamens moderately unequal in insertion : capsule globular, 3-seeded. 

 C. glutinosa, Benth. iii DC., a more viscid form. Gilia divaricata, Nutt. PI. 

 Gamb. 155. 



Moist ground, common through the western part of the State, and extending to the Sierra 

 Nevada : variable. 



6. C. heterophylla, Hook. A span or two in height, diffuse : leaves mostly 

 pinnately parted or the upper pinnatifid, and the lobes incised or cleft ; the upper- 

 most often entire and broader, subtending the capitate-clustered flowers (or these 

 rarely somewhat scattered) : lobes of the merely 5-cleft calyx ovate-lanceolate or tri- 

 angular, acute ; base of the tube in fruit acute : corolla purplish, half an inch long : 

 stamens very unequally inserted : capsule oval ; the cells 1 - 3-seeded. Bot. Mag. 

 t. 2895 ; Bot. Eeg. t. 1347. Courtoisiabipinnatijida, Eeichenbach, Ic. Exot. t. 208. 

 Navarretia heterophylla, Benth. in DC. 



Moist ground, Monterey to British Columbia. Stamens sometimes short, sometimes longer. 



2. Corolla funnelform : seeds or at least the ovules several in each cell. 



7. C. leptalea, Gray. Slender, with diffuse and filiform branches, 2 to 18 

 inches high, minutely glandular : leaves narrowly linear, entire, or some of the 

 lowest occasionally with 2 or 3 small lobes : flowers effusely panicled, on naked 

 filiform peduncles : calyx small, its lobes subulate : corolla pink-red, 5 to 10 lines 

 long, with slender tube longer than the calyx, and rather abruptly expanded into a 

 wide-funnelforrn throat about the length of the oval spreading lobes. Proc. Am. 

 Acad. viii. 261 ; Watson, Bot. King Exp. 262, t. 65. Gilia capillaris, Kellogg in 

 Proc. Calif. Acad. v. 46. 



Common on moist or wet banks, and more depauperate in drier soil, in the Sierra Nevada, at 

 4,000 to 9,000 feet. Unlike any of the foregoing in habit.
