BOTAITY. 
September. Miicli 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 heterosepala, 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 long, upper ones oblong-lanceolate ; 
flowers solitary or fascicled in the axils, on unequal (3"-li') 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.) Ruby and Hunt- 
ington Valleys, Nevada, and Bear River Valley in the Uintas ; 6-8,000 feet 
altitude ; July, August. (949.) 
Gentiana frigida, Hsnke. DC. Prodr. 9. 111. Perennial, with a single 
ascending stem ; leaves spatulate-linear, obtuse, not cartilaginous and nearly 
smooth on the margin, flowers subsoHtary, 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 shoi-t, 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 arc 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
