2 - 3-tootlicd and acute, half a line long : seeds not mucilaginous when wetted ! — 

 Proc. Am. Acad. viii. 278 ; Watson, Bot. King Exp. 270, t. 26, fig. 6, 7. 

 Northwestern Nevada, on the borders of California (Watson, Lcmmon) ; east to Utah. 

 = = Corolla campiiiinl'ii, , white or nearly so : seeds few. 



45. G-. micromeria, Gray. Diffuse, 2 or 3 inches high, very slender, almost 

 glabrous : radical and lower leaves pinnatifid, with linear-oblong very obtuse lobes ; 

 those of the branches linear and entire, gradually reduced to bracts : flowers sparse, 

 mainly opposite the leaves, on long filiform at length somewhat refracted pedicels : 

 corolla barely a line long, little exceeding the calyx : capsule globular, longer than 

 the style. — Proc. Am. Acad. viii. 279 ; Watson, 1. c. t. 20, fig. 12 - 16. 



Northwestern Nevada, Truekce Valley to the East Humboldt Mountains, Watson. Probably 

 reaches California. 



40. G-. campanulata, Gray, 1. c. Diffuse, 2 or 3 inches high, somewhat 



pube-eeiil and vi-o-id ; lower l.-aves lanceolate, sparingly toothed or incised (half an 

 inch long) ; those of the slender paniculate branches similar, or narrower and entire : 

 pedicels mostly shorter than the flower : corolla 4 lines long, with hardly any proper 

 till"-, moderately 5-lobed, about twice the length of the lanceolate-subulate lobes 

 of the deeply parted calyx : these scariously margined toward the base : stamens 

 inserted low down: ovules 6 or 7 in each cell. — -Watson, 1. c. t. 26, fig. 10- 18. 



Banks of the Truukee River, Nevada, Watson. Perhaps extending to California. Flower not 

 unlike that of the first species lure described, viz., G. demissa. 



G. filtformis, Parry, a newly discovered species of Southern Utah, related to the last, has 

 smaller and cream-colored flowers on filiform at length refraeted pedicels, and almost filiform 

 entire leaves. 



6. mini rriFLORA, Bcnth., of a peculiar section, — with very small flowers, 5-toothed calyx, 

 salverform corolla, and solitary ovules, — has been attributed to California, but is known only 

 from the interior of Oregon and eastward. 



4. POLEMONITJM, Tourn. Greek Valerian. 



Flowers as in Gilia § Eugilia, but the corolla short and broad, the stamens 

 si mil- what declined, the filaments hairy-appendaged at base. — Perennial or rarch 

 animal herbs : with pinnate or pinnately parted leaves, and mostly showy flowers. 

 Calyx herbaceous; its divisions and those of the leaves pointless. Corolla more 

 commonly blue, varying to while. 



The few species are all North American, either northern nr of elevated districts ; two of them 

 also of the Old World. The genus, sufficiently well marked as to the original species, is much 

 invalidated by the annual /'. micranthum on the one hand, and one or more with funnolform 

 corolla on the other. 



§ 1. Annual, diffun : rotate corolla shorter than the calyx : flowers scattered. 



1. P. micranthum, Benth. Low, weak and diffusely spreading or procumbent, 



:; to 8 inches high, v isi id pubescenl : leaflets 5 to 13, obovate or lam late (2 to t 



lines long): corolla rotate, white or whitish, and decidedly shorter than the deeply 

 5 clefl calyx : seeds 5 to 9. — DC. Prodr. ix. 318. 



Moist grounds, sierra Co. (Lemmon), and adjacent borders of Nevada — 

 north to British Colombia. 



§ 2. Perennial-: corolla rotate-campanulate from a very short somewhat obconical 

 lube; limb surpassing the calyx: inflorescena cymose or thyrsoid-panicled. 



2. P. humile, Willd. A -pan high, commonly in tufts from rather slender 

 rootstocks, minutely viscid-pubesceni or almost glabrous: leaflets II to 21, from ob- 

 long-lanceolate to oval, and from 2 to 7 lines long, either scattered or crowded, 

 • ■utile: cymes corymbose, few-flowered, loose: calyx deeplj 5-cleft : corolla (blue,
