purplish: pappus-bristles 3, seldom obsolete. — Bull. Torr. 

 Club IX. 109, & Bot. Gaz. 1. c. Gray, Syn. Fl. 1. c. 



About Sau Francisco and eastward to the foot-hills of the 

 Sierra Nevada; common, but often depauperate, and always 

 an inconspicuous plant. 



BIGELOVIA. 

 B. furfuracea. 



Leaves thick, narrowly oblanceolate, 1 — 2 inches long, 

 entire, covered on both sides with close resinous scales, re- 

 sembling scurf, which extend also to the branches and 

 branchlets : inflorescence corymbose-panicled;,head 4 — 5 lines 

 high, 12 — 15-flowered: involucre turbinate, its scales char- 

 taceous, with blunt greenish tips and more or less white- 

 tomentose: style-appendages short-subulate: pappus of very 

 unequal bristles: akenes strongly silky-pubescent. 



A most singular looking species in respect to the resinous 

 scales resembling scurf, on the branches and foliage. The 

 specimen consists of a single branch, in flower, and well 

 preserved. The name of the collector is unknown, and the 

 habitat of the species is equally enigmatic; but we suspect 

 it to have come from Lower California. 



ERIGERON. 



In the small group of perennial, tall, leafy-stemmed spe- 

 cies inhabiting and almost peculiar to California, a different 

 arrangement is called for by those who are familiar with the 

 plants in their native haunts, from that given in the Synop- 

 tical Flora of North America. In the herbarium of the 

 Academy, most of the forms are abundantly represented, 

 and are disposed as follows : 



E. Stenophyllus, Nutt. not of Gray. 



Herbage deep green: stems ascending from a decumbent 

 base, about two feet high, stoutish, rigid, brittle and some-
