Pohmonium. POLEMONIACE^E. 499 



2 - 3-toothed 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, Lemmon) ; east to Utah. 

 = = Corolla campanulate, white or nearly so : seeds few. 



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

 glabrous : radical and lower leaves piunatitid, 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. 26, fig. 12-16. 



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

 reaches California. 



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

 pubescent and viscid : lower leaves 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 

 tube, 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. 16-18. 



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

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



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

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

 entire leaves. 



G. MINUTIFLORA, Benth., of a peculiar section, with very small flowers, 5-toothed calyx, 

 salverfonn 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 Euyilia, but the corolla short and broad, the stamens 

 somewhat declined, the filaments hairy-appendaged at base. Perennial or rarely 

 annual 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 white. 



The few species are all North American, either northern or 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 P. micranthum on the one hand, and one or more with funnelform 

 corolla on the other. 



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



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



3 to 8 inches high, viscid-pubescent : leaflets 5 to 13, obovate or lanceolate (2 to 4 

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

 5-cleft calyx : seeds 5 to 9. DC. Prodr. ix. 318. 



Moist grounds, Sierra Co. (Lemmori), and adjacent borders of Nevada (Anderson, Watson), 

 north to British Columbia. 



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

 tube ; limb surpassing the calyx : inflorescence cymose or thyrsoid-panicled. 



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

 rootstocks, minutely viscid-pubescent or almost glabrous : leaflets 11 to 21, from ob- 

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

 entire : cymes corymbose, few-flowered, loose : calyx deeply 5-cleft : corolla (blue,
