wliolly exserted ; the lower lip extremely short, callous and protuberant. — C. can- 

 dens, Durand in Pacif. II. Eep. v. 12. 



Sides of rocky hills, near Fort Tejon and in the Sierra Nevada, chiefly in the eastern ranges 

 and at about 8,000 feet ; thence along the mountains to New Mexico, Colorado, and Wyoming " 



§ 3. Perennial: calyx cleft more or less behind as well as before; the lobes therefore 

 right and left, two and entire or notched, or else %parted, making 4, variable 

 in this res2ject. 



% White-woolly, leather shrubby at base. 



4. C. foliolosa, Hook. & Arn. A foot or two high, clothed with a matted white 

 wool (consisting of intricately branched hairs), which becomes loose with age : 

 leaves rather short and very numerous, being often in fascicles in the axils, lin'ear 

 and entire, or with a pair of linear divaricate lobes ; the upper floral cleft and their 

 lobes with more or less dilated yellowish or red tips : the 2 calyx-lobes broad, retuse 

 or merely notched, nearly equalling the corolla, the lower lip of which is very 

 small. — Bot. Beechey, 154 ; Gray in Bot. Mex. Bound. 118. 



Hillsides, Mendocino Co. to San Diego, most common southward. Seeds elongated-oblon<r 

 somewhat club-shaped. '^ 



* % Pubescent or villous-hirsute with siviple hairs, or below glabroiis, herbaceous. 



-f- Leaves short and small, broad and obtuse. 



5. C. latifolia, Hook. & Arn. 1. c. A foot or two high, diffusely branched from 

 the base, the copious soft-hirsute pubescence viscid : leaves from round-obovate to 

 oval, half an inch to an inch long, sometimes 3 - 5-lobed, especially the dilated 

 floral ones, the uppermost red ; the 2 calyx-lobes broad and notched or 2-lobed at 

 the summit, longer than the tube of the corolla ; the lower lip of which is very 

 short, callous, and the teeth inflexed. 



Along and near the coast, Mendocino Co. to Monterey. Corolla about two thirds of an inch 

 long ; the narrow ujiper lip rather longer than the tube. 



-(- -H Leaves or their lobes from lanceolate-oblong to narroivly linear. {The species 

 variable and difficidt.) 



++ Upper lip of the corolla elongated, as long as or longer than the tube, many times 

 longer than the very short lower lip : floral leaves or their lobes dilated and pietaloid, 

 scarlet or crimson, rarely yelloivish or whitish : calyx mostly tinged with the same 

 color : corolla yelloivish often tinged with green, sometimes with red. 



6. C. parviflora, Bongard. From villous-pubescent to hirsute, especially above, 

 a span or two to a foot or two high : leaves laciniate-cleft or incised, sometimes

Open grounds, from the mountains behind San Diego northward througliout the State, extend- 

 ing to Sitka, and through the mountains to Dakotah, &c. The earlier name is the least appro- 

 priate and is even misleading ; the flowers when well developed being as large as in the eastern 

 C. coccinea, or even larger, except in some dwarfed mountain forms. Sac below the teeth of the 

 lower lip thin and little ]irqjecting, longer than deep, 3-carinate ; the teetli (at first involute and 

 always small), remarkably variable, sometimes lanceolate and acute and as long as the saccate 

 portion, or the middle one shorter or obsolete ; sometimes all short and ovate or deltoid ; occa- 

 sionally all three truncate and extremely shoi't. 



7. C. ininiata, Dough Glabrous below, more or less pubescent above, commonly 

 2 feet high, strict, often slender : leaves lanceolate or linear-lanceolate, almost always
