CONVOLVULACE^. 



Calystegia sepium, L. — Malade Valley, Idaho, June. 



Cuscuta ,(f) — The specimen found was too young to determine 



anything as to its species. It was growing on Oxytropis Lamherti^ 

 Henry's Fork of Snake Eiver. 



SOLANACE^. 



Solanum trifiorum, Nutt. — Uintah Mountains, Wyoming, August. Br. 

 Joseph Leidy.

GENTIANACEiE. 



Genfiana Amarella, L. — Henry's Lake, Idaho, August ; Heart Lake, 

 Wyoming, September. 



Gentiana detonsa, Fries. — Henry's Fork of Snake Eiver, August. This 

 species occurred in the Fire-Hole Basins in great abundance, but with 

 leaves and stems so black as to be scarcely recognizable. " The pedun- 

 cles are shorter, and the lobes of the corolla more strongly lacerate 

 fringed than usual. It approaches G. crinita, with which it is probably 

 identical." Professor Porter. 



Gentiana affinis, Smith. — Teton Basin, August; along the Yellowstone, 

 elevation 6,400 feet ; Henry's Fork of Snake Eiver, August. 



Gentiana simplex^ Gray. (Pacif. E. E. Eep., vol. vi, p. 87, pi. 16.) — 

 " It accords well with the description and figure, except that the leaves 

 are shorter and the lobes of the corolla rounded, very obtuse, and occa- 

 sionally furnished at the base with a few small teeth." Professor Porter. 

 Henry's Fork of Snake Eiver, August. 



Gentiana calycosa^ Griesb., (in D. 0., Prod. 9, p. 115, and Hooker's Fl. 

 Bor. Am. 2, p. 18, t. 14G.)— Teton Caiion, 10,000 feet altitude. ^' It varies 

 from the typidal form in its shorter calyx and calyx-lobes, and the smooth 

 edges of its thinnish leaves." Professor Porter. 



Frasera speciosa, Dougl. — Teton Canon, July ; Snake Eiver Valley. 



Sivertia perennis, L. — Uintah Mountains, Wyoming, August. Br.
