oblong, 2-3" long, more or less acute ; stigma somewhat cup-shaped, slightly 

 2-lobed ; capsule 4-7" long, becoming nearly twice longer than the calyx ; 

 seeds oblong or roundish, minutely pitted. — Stem 3-12' high, branching from 

 the base or only toward the top. Nearly E. Chilensis, but with larger flowers, 

 longer capsule and less lobed stigma ; easily distinguished from other western 

 species by its loose few-flowered habit and long peduncles. It is E. longiflora, 

 E. elata, and E. tenella, of Nutt. Mss., from Northern Utah and Southern 

 Idaho, and 29 Anderson from near Carson City. As none of Nuttall's pro- 

 posed names are always appropriate, the species is best dedicated to him- 

 self Found in Unionville, Huntington, and Ruby Valleys, Nevada ; 4,500- 

 6,000 feet altitude ; August-October. Plate XXIX. Figs. 1, 2. Plants ;

Gentiana Amaeella, L. DC. Prodr. 9. 95. Stem slender, erect, 

 branched ; lowest leaves oval- or oblong-spatulate, upper ones ovate or ovate- 

 lanceolate, sessile and subclasping, margins scabrous ; cyme usually com- 

 pound and raceme-like ; calyx 5-cleft, lobes lanceolate, somewhat unequal, 

 shorter than the corolla-tube ; corolla pale-blue, without folds, fringed at the 

 base of the limb, lobes elliptic-lanceolate, shorter than the tube ; ovary oblong- 

 linear, sessile. — There can be no doubt of the identity of G. acuta and Q. 

 tenuis with this species, as pointed out by Dr. Hooker and Dr. Engelmann. 

 None of the points of diiference indicated by Grrisebach — the nearly connate 

 leaves, their shape, the thinner beard, the smaller flowers with shorter and 

 more unequal calyx, the more angular taller and more branched stem — are at 

 all constant. From the mouth of the St. Lawrence westward to the Pacific 

 and northwest to Great Bear Lake and Unalaska ; Eocky Mountains of Col- 

 orado and Wyoming, and the Sierras of Northern California. The present 

 specimens are a subalpine form, 2-10' high ; leaves broad and mostly obtuse; 

 flowers variable in size, 3-6" long, rather few and scattered ; calyx cleft nearly 

 to the base, the lobes sometimes very unequal; corolla with abundant fringe^ 

 no glands, lobes more or less acute. — East Humboldt Mountains, Nevada, 

 and in the Uintas ; 8-9,500 feet altitude ; July, August. (946.) 



Var. STEiCTA. {G. acuta, Mx., Var. stricta, Griseb. DC. Prodr. 9. 96.) 

 Stem 2-4° high ; cymes axillary, strict, elongated, erect. — Huntington and 

 Ruby Valleys and near Humboldt Pass, Nevada ; 6,000 feet altitude ; August,
