492 POLEMONIACE.E. Gitia. 



Hillsides, Mariposa to Sierra and Mendocino Counties, and along the western borders of Nevada. 

 Grayish with short pubescence on the steins, and with long hairs, both soft and rigid, on the upper 

 leaves. 



* * Stems leafless below : leaves entire : anthers senile in the throat of the corolla. 



13. GK nudicaulis, Gray. An inch to a span high, wholly glabrous, simple or 

 "branched from the base : leaves several and densely crowded, forming an involucre 

 around a terminal capitate cluster of flowers, linear to ovate-lanceolate, obtuse, 

 rather fleshy, half an inch long; the small ovate cotyledons usually persisting 

 below : corolla white, pinkish, or pale yellow ; its lobes cuneate, with repand or 

 1 3-toothed summit, 2 or 3 lines long, shorter than the slender tube. Proc. Am. 

 Acad. viii. 266. Collomia nudicaulis, Hook. & Arn. Bot. Beechey, 369. 



Moist sandy ground, along the eastern borders of the State (Carson City, Anderson, &c.) to 

 Utali and Colorado. 



4. Flowers as in 3 ; but tube of the corolla not exceeding the calyx, the throat 

 more funnelform, and ovules only 2 to 4 in each cell : filaments and anthers 

 short : perennials, more or less woody at base : leaves opposite and 3 - 7 -parted, 

 so appearing to be ivhorled. SIPHONELLA, Gray. 



14. Gr. Nuttallii, Gray. A span to a foot high, many-stemmed from the 

 woody subterranean base : divisions of the leaves narrowly linear, rigid (half to 

 three fourths of an inch long), mucronate, hispidulous-scabrous, the lower shorter 

 than the internodes : flowers in a capitate terminal cluster : calyx rigid, cylindra- 

 ceous, soon 5-parted, not scarious, the lobes lanceolate-subulate : ovules a pair in 

 each cell. Proc. Am. Acad. viii. 267 ; Watson, Bot. King Exp. 265, t. 26, fig. 8. 



Eastern borders of the Sierra Nevada (near Carson City and on Silver Mountain, Anderson, 

 Brewer) ; thence to Utah and Arizona, 



15. Gr. floiibunda, Gray, 1. a- Taller, more slender and bushy, corymbose at 

 summit : divisions of the leaves acerose (half to a full inch long), and nearly 

 smooth : flowers cymose-clustered (delicate-scented), some of them rather slender- 

 pedicelled : ovules 4 in each cell. 



Near the southern borders of the State, Coulter, E. W. Morse, Cleveland. Also Arizona, Palmer. 



II. All the leaves alternate (in our species) and palmately parted, crowded on the 

 woody stems. (Seeds unaltered in water, developing neither mucilage nor 

 spiral threads.) 



5. Corolla salverform, with tube more or less exceeding the calyx : filaments short, 

 inserted in or below the throat : anthers short, included : ovules numerous in 

 each cell : seed- coat close, as in Phlox, developing neither spiral threads nor 

 mucilage when wetted : ivoody based perennials or undershrubs, Phlox-like, 

 very leafy : leaves alternate, except in one species, and much fascicled in the 

 axils, palmately 3 7 '-parted ; the divisions acerose or subulate, rigid and 

 pungent : fiowers showy, sessile, solitary or few in a cluster at the end of short 

 branches or branchlets. LEPTODACTYLON, Benth. (Leptodactylon, Hook. & 

 Arn.) 



G. WATSONI, Gray, of Utah, is remarkable for its opposite leaves, and nearly herbaceous flow- 

 ering-stems. The following are decidedly shrubby. 



16. Gr. Californica, Benth. in DC. Two or three feet high, Avith spreading 

 rigid branches, villous or soft-pubescent when young : leaves widely spreading : 

 corolla rose-color or lilac ; the ample limb an inch and a half in diameter, and the 

 broadly cuneate-obovate lobes often erose on the margins : anthers linear-oblong, 

 included in the upper part of the tube : ovules 20 or more in each cell. Leptodac- 

 tylon Californicum, Hook. & Am. Bot. Beechey, 349, t. 89 ; Bot. Mag. t. 4872. 



Dry hills, throughout the southern part of the State, and north at least to Monterey. A hand- 

 some species.
