CONTRIBUTIONS TO WESTERN BOTANY. 689 



and without the slightest evidence of a thin prolongation 

 beyond, but the specimens are referred to C . glomeratiis 

 because of the less thickened wing. I have shown in 

 Zoe that C . glomeratiis shares with C . Fendle^-i the char- 

 acter of a thickened central portion of the wing, that por- 

 tion next the seed being fully as thin as the portion out- 

 side of the corky part. In view of these facts I see no 

 escape from making this a variety of C . glomeratus, whose 

 geographical range seems to be that portion of the Great 

 Plateau west of the plains, including western Wyoming, 

 Idaho and Montana. 



Peucedanum triternatum var. alatiim Coulter and Rose 

 is a true Pseudocymopterus , with raised winged ribs, and 

 certainly connects Peucedanum with Cymopteriis, as the 

 latter genus is now received. If Pseudocymopteriis is to 

 be retained its limits certainly must be changed. 



MeNTZELIA IMULTIFLORA var. INTEGRA. 



No. 6082c. September 26, 1894, Rockville, Utah, 

 4000° alt., in red sand. 



No. 54i9e. June 14, 1894, Salina Canon, Utah, four 

 miles up, at 5300° alt. 



No. 5263. May 19, 1894, on grade south of Rockville, 

 Utah, in clay, 4500° alt. 



Leaves oblanceolate, simply and bluntly toothed or 

 lobed; flowers long pediceled and bractless; seeds nearly 

 orbicular, large, broadly winged. To this I refer Palmer's 

 specimen from southern Utah, No. 171, referred in the 

 National Herbarium to 31. chrysantha. 



This grows on very barren clay soil. 



Sym^horicar-pus rotundifoliiis Gray. 



No. 5261m. May 17, 1894, Springdale, Utah, 4000° 

 alt., in red sand. 



No. 5447d. Salina Pass, June 16, 1894, 8000° alt., in
