 Washoe Valley, Nevada, Mr. Stretch, the male plant ; Sierra County, 

 California, J. G. Lemmon, male and female. Remarkable for its 

 small, narrow, and loosely paniculate heads : the silvery pubescence 

 finer and closer even than in A. luzuhides. 



Senecio Grkenei. Primum araneoso-subtomentosa, mox glabrata; 

 caule simplici e radice perenni subpedali 1-3-cepbalo; foliis plerisque 

 radicalibus ovali-subrotundis crenato-dentatis basi subcuneatis longius 

 petiolatis, caulinis parvis subspathulatis superioribus in bracteas subu- 

 latas decrescentibus ; involucro campanulato 20-phyllo ecalyculato ; 

 lio-ulis 9-1 4 lato-linearibus flammeis vel croceis : styli ramis cono ob- 

 tusissimo annulo setularum cincto centro cuspidate superatis ! — Cali- 

 fornia, in woods near the Geysers, E. L. Greene, who, although new 

 to California, has found this distinct species in a district often visited 

 by botanists and amateurs. Blade of the radical leaves barely an inch 

 or two long. Involucre fully half an inch high, and the flame-colored 

 rays half an inch long: tips of the disk-corollas also orange. The 

 fringe around the style-tips and the setulose cusp are found in no 

 other genuine North American species. Akenes glabrous.

 — California, in crevices of rocks in the mountains of Lake County, 

 E. L. Greene, June 19. — Leaves about an inch long. Corolla about 

 5 lines long ; the short upper lip above the gorge furnished with a 

 peculiar palatine crest of two conspicuous obtuse callous teeth on each 

 side, connected by a less elevated ridge ; lateral lobes of the lower lip 

 unusually small. Filaments and the inside of the oblong saccate throat 

 (which is longer than the limb) beardless. A peculiar species, one of 

 the early fruits of Mr. Greene's close observation in the region in which 

 he has recently taken up his residence.
