278 BOTAIffT. 



September. Mucli branched or nearly simple ; leaves narrower in propor- 

 tion than in the last and flowers rather smaller, more numerous and crowded; 

 corolla-lobes acute or obtuse ; obscure glands are sometimes found at the 

 base. (947.) 



Gentiana heteeosepala, Eng. Trans. Acad. St. Louis, 1.215. Annual, 

 low, erect, simple, few-flowered, glabrous ; lowest leaves obovate-spatulate, 

 upper ones ovate, broad at base, sessile, acute or subobtuse, margin minutely 

 scabrous ; flowers short-peduncled ; calyx 5-cleft, two of the lobes large, 

 ovate, acute, nearly equaling the corolla, the remaining three shorter and 

 linear-subulate; corolla with obscure glands at base, sparingly bearded, the 

 lobes linear-oblong, obtuse, spreading, half as long as the tube ; anthers ovate- 

 cordate ; pistil linear. — The specimens are much larger than the original 

 ones of Engelmann, 4-16' high, and with a rather full beard, but the charac- 

 ters of the calyx hold good ; leaves J-li' long, upper ones oblong-lanceolate ; 

 flowers solitary or fascicled in the axils, on unequal {3"-lh') and often long 

 peduncels or subcymose upon a common peduncle, pale-blue, 6-8" long ; hairs 

 of the fringe in two fascicles at the base of each lobe. Wahsatch and Uinta 

 Mountains, Utah ; 8-8,500 feet altitude ; July, August. (948.) 



Gentiana detonsa. Fries. This is referred to G. crinita as a variety, 

 but, as the older species, should be retained. From Canada and the Lakes 

 to the Arctic Ocean, (Point Barrow, Fort Youkon,) and Rocky Mountains ; 

 Southern Idaho, (Tolmie ;) Colorado, (Hall & Harbour.) Euby and Hunt- 

 ington Valleys, Nevada, and Bear River Valley in the Uintas ; 6-8,000 feet 

 altitude; July, August. (949.) 



Gentiana frigida, Hsenke. DC.Prodr. 9. 111. Perennial, with a single 

 ascending stem ; leaves spatulate-linear, obtuse, not cartilaginous and nearly 

 smooth on the margin, flowers subsolitary, terminal ; calyx 5-cleft, the lobes 

 oblong-linear, half as long as the corolla ; corolla plaited, glandless and beard- 

 less, narrowly obconic, whitish with blue spots, the lobes short, ovate, three 

 times longer than the folds ; anthers free, erect ; testa slighty winged ; capsule 

 at length stipitate. Var. algida, Pall. Stem taller but low ; leaves broader ; 

 flowers several, pedicelled, twice larger ; calyx somewhat unequal and some- 

 times split. — The specimens are not yet in flower, but are evidently the same 

 as the form collected in the Rocky Mountains of Colorado, considered by 

 Engelmann intermediate between the European frigida and the Siberian 

 variety. 3-6" high ; radical leaves often 3-4' long and 2-4' wide, cauline
