EEYTHEA. 



(1840).— Oregon and Washington. Plant with the fastigiate- 

 cymose inflorescence of true Chrysopsis. 



25. C. EUDis, Greene, Man. 174 (1894).— Almost through- 

 out California. In pubescence, mode of branching, and other 

 particulars entirely distinct from the last; even bearing but 

 little general resemblance to it. The variety scaberrima 

 (C. Oregana var. scaherrima, Gray, Syn. Fl. 124) is said to 

 have small leaves, and to be very hispid. It is of a more 

 southerly station, and perhaps specifically distinct. 



•M- -M- Flaccid and smooth siihalpine species with open 



inflorescence. — Subgenus Oeeobia. 



26. C. Breweri, Gray, Proc. Am. Acad. vi. 542 (1865).— 

 Northern and middle Sierra Nevada, California.

High mountains of southern California. 



A number of plants, wrongly included in this genus by 

 Nuttall, and by Elliott, were excluded by DeCandolle; but 

 the following, added more recently to Chrysopsis, easily 

 admits of another disposal. I shall call it 



Erigeron Mendocinus. Chrysopsis andicola, Philippi, 



Anal. Univ. Chil. ii. 398 (1862); LinnsBa, xxxiii, 131. From 

 Dr. Philippi's description alone we inferred that this plant 



igeron. The very numerous and narrow rays, 

 blunt style-tips, etc., seemed to imply as much; for with us 

 who know the several yellow-flowered North American 

 Erigerons, the color of flowers in this plant would not be 

 misleading. The one good specimen which I have seen 

 shows the species to be a near relative of our Californian 

 group of Erigerons, having leafy stems, and terminal solitary 

 or corymbose heads— a group in which most of the species 

 are destitute of rays. There is an earlier Erigeron 

 andicola, DC. 



What appears to me as another excellent natural genus 

 of plants, the type species of which is merged in ''Aplo- 

 pappus'' by Asa Gray and Mr. Bentham, is NuttalFs
