t. 20. P. moschatum, Wormskiold. P. luunile, Lindl. Bot. Reg. t. 1304. P.pulcherrimum^ook. 

 Bot. Mag 1 , t. 2979, a more viscid, lax or diffuse, and small-flowered form ; the corolla violet, 

 varying to white, its lobes narrower. N. W. and Arctic coast, and southward along the 

 Rocky Mountains to Colorado and the Sierra Nevada. (Kamts. & Siberia.) 

 * * Taller, from slender rootstocks or roots : leaves and leaflets larger. 



H Ovules G to 12 in each cell: stem erect, 1 to 3 feet high: leaflets numerous and mostly approxi- 

 mate, not rarely continent or the rhachis winged: seeds in the same species either wing-angled 

 or marginless : "corolla blue, varying to white. 



P. caeruleum, L. Either glabrous or viscid-pubescent : stem mostly strict and virgate, 

 1 to 3 feet high, 5-10-leaved : leaflets from linear-lanceolate to oblong-ovate (9 to 20 lines 

 long) : flowers numerous in a naked and narrow thyrsus or panicle: calyx cleft to or be- 

 yond the middle: corolla an inch or considerably less in diameter: elongated style usually 

 considerably and stamens often somewhat longer than the corolla. Fl. Dan. t. 255; 

 Reiehcnb. Ic. Germ. t. 1334 ; Gray, Man. ed. 5, 371. Wet or moist ground ; very rare in 

 the N. Atlantic States (in swamps in New York, viz. Schoharie Co., Dr. Howe, Delaware 

 Co., B. D. Gilbert, Hcrkimer Co., Clinton, also Warren Co., New Jersey, Porter; a form with 

 rather open-panicled inflorescence and broadish leaflets) ; but common in western wooded 

 mountain districts, viz. from Colorado Rocky Mountains to California, Oregon, and far 

 northward. (N. Asia, Eu.) 



Var. acutiflorum, Ledeb., is a high northern and reduced form, a foot to a span 

 high, with few and large flowers, and ovate more or less acute corolla-lobes, which exceed 

 the stamens and sometimes even the style. P. acutiflorum, Willd. in Roem. & Sch. 1. c. ; 

 DC. Prodr. 1. c. High N. W. coast and Aleutian Islands, &c. (Siber., N. Eu.) 



P. foliosissimum. Very viscid-pubescent throughout and strong-scented : stem a foot 

 or more high, very leafy throughout: leaflets from lanceolate to ovate-lanceolate (seldom 

 an inch long) : flowers corymbose-cymose, smaller than those of the preceding : corolla 

 commonly white or cream-color, sometimes violet, twice the length of the calyx, which is 

 5-cleft to or beyond the middle : style and stamens not protruding. P. acruleiim, var.? 

 pterosperma, Benth. in DC. Prodr. ix. 317 ; but the seeds, as in P. azruleum, are either mar- 

 ginless or wing-margined. P. cceru/enm, \&r. foliosissimum, Gray, Proc. Am. Acad. viii. 281. 

 Rocky Mountains of New Mexico, Colorado, and Wyoming, and west to Utah and Idaho. 

 Some forms approaching the preceding species ; but it is more like P. Mexicanum, Cerv., 

 which is loosely branched, and has the violet corolla little exceeding the calyx, the lobes of 

 the latter barely half the length of the tube. 



.)__ -I Ovules onlv 3 or 4 in each cell : stem lax or with diffuse branches and open corymbiform or 

 paniculate inflorescence: leaflets fewer (5 to 15) and rather large, membranaceous, only the ulti- 

 mate at all confluent : herbage glabrous or slightly pubescent, neither viscid nor glandular: style 

 and stamens rather shorter than the corolla. 



P. carneum. A foot or two high, rather stout: leaflets from ovate to oblong-lanceolate 

 (often an inch and a half long): branches somewhat umbellately 3-5-flowered: calyx 

 deeply 5-cleft ; the lobes ovate-oblong : corolla salmon-color or flesh-color (fading to pur- 

 plish), 8 to 12 lines long (the ample limb sometimes 1$ inches in diameter when fully 

 expanded); its lobes rounded-obovate. In mountain woods, Siskij'ou Co., California, 

 Greene. Also near San Francisco, Kcllojg, G. li. Vascy. 



P. reptans, L. A foot or less high, slender, weak and at length diffuse or spreading (but 

 never creeping) : leaflets ovate- or lanceolate-oblong: flowers several and loosely panicu- 

 late-cymulose on the branches : calyx with ovate lobes shorter than its tube : corolla light 

 blue, half inch or less in length. Lam. 111. 1. 106 ; Bot. Mag. 1. 1887. Open woods, New 

 York to Alabama and west to Minnesota and Missouri. 



3. Corolla almost rotate, shorter than the broad and open deeply 5-cleft 

 calyx : filaments almost naked at base: flowers scattered: root annual. (Another 

 transition to Gilia.) 



P. micranthum, Benth. Much branched from the base, slender, diffuse, more or less 

 viscid-pubescent : stems or branches 3 to 8 inches long : leaflets 5 to 13, obovate or lanceo- 

 late (2 to 4 lines long) : peduncles mostly solitary opposite the leaves : corolla whitish, a 

 line or two long: ovules 2 or 3 in each celt. DC. Prodr. ix. 318; Gray, 1. c. Springy 

 ground, British Columbia to California and Nevada : fl. in spring. (S. Chili, P. antarcticum, 

 Griseb. ex Benth.)
