■ 



cept at the very base, those of the rays more hairy ; hairs soft, as 

 long as the width of the akene, many of them bidentate at apex, 

 the teeth spreading or recurved.. 



Wallowa Mts., northeastern Oregon, 7000-8000 feet altitude, 



» 



IV C. Cusick, no. £2g»^collected July 31, 1899. The species is 

 apparently nearest to T. Arizonica Gray. 



Erigeron Chrysopsidis Gray, Syn. Fl. I: 210. 1884 



Erigeron oclirolencus hirtellus Gray, Proc. Am. Acad. 16: 

 90. 1880. 



The type sheet of this species contains the four following speci- 

 mens from which the description in the Synoptical Flora was drawn 

 up, namely : 



" Mts. Oregon, Cusick, 1877." " Interior of Oregon, Nevins, 

 1877. " " In stiff clay on mountain slopes, Rev. R. D. Nevins, 

 1877." M Stony hills, John Day's Valley, E. Oregon, May, 1880, 

 Howell Bros." No. 200; also a fifth collection by Suksdorf, no." 

 349, "Plains, southwest of Morgan's Ferry, Yakima Co., Wash., 

 June 7, 1884." This last specimen is the basis for the note in 

 Syn. Fl. Supp. I., 447, 1886. It is clearly a different plant from 

 the others, but agrees exactly with several later collections. A 

 careful study of DeCandolle's description of Chrysopsis hirtella, 

 Prodr. 5 : 327, leaves scarcely a doubt that the Douglas plant from 

 the Columbia River there described is the same as the Suksdorf 

 plant. This is discussed below. Of true Erigeron Chrysopsidis, 

 Gray, excellent specimens have recently been distributed by Mr. W. 

 C Cusick under no. 2187, from the Blue Mts., Oregon. These 

 specimens have leaves sometimes 8-10 cm. long, but always truly 

 spatulate. The heads of this species are 2-3 cm. high, the rays 

 2 cm. long. 



\j Erigeron Chrysopsidis brevifolius var. no v. 



Densely caespitose, bearing scapes 4—6 cm. high : leaves 1— 1.5 

 cm. long: heads 2 cm. high, the rays 1.5 cm. long, golden yellow. 



Subalpine ridges of the Wallowa Mts., northeastern Oregon, 



7000 ft. altitude, IV. C Cusick, no. 2270, July 27, 1899. Differs 

 from the type in being smaller in every way and having relatively 

 much shorter leaves.
