 bearing a whorl of bracts above midway and a single large globose 

 tiower-cluster of 1 or more small involucres : fl. yellow ; the campanu- 

 late perianth abruptly narrowed to a short stipitiform base : filaments 

 long-villous for a short space below the middle. — A neat and pretty 

 alpine species, found at Sonora Pass, Brewer, and again from the 

 Scott Moimtains northward ; more common on the high plains of 

 eastern Oregon. Aug. 



5. E. Torreyanuin, Gray, Proc. Am. Acad. viii. 58 (1870). Glabrous,

 nodes all leafy-bracted : fl. yellow : stipitate base of perianth elongated. 

 Var. bahiaeforiiie, Wats. Inflorescence more compound ; leaves smaller 

 and more decidedly tomentose. Rather common in the Sierra; also 

 apparently in the Coast Range northward. 



7. E. robustum, Greene, Bull. Calif. Acad. i. 126 (188.5). Whitish-

 long : peduncles stout, erect, 6 in. high, bearing an ample umbel of

 by spatulate, the latter by linear-lanceolate leafy bracts 1 in. long : 

 involucres % in. long : fl. cream-colored, }i in. long ; stipe like base of 

 perianth very short. Eastern foot-hills of the Sierra between Reno and 

 Virginia City, Nevada, Mrs. Cur ran. Not yet found within the Cali-
