346 PHANEROGAMOUS PLANTS. 



2. Linosyris (Chrysothamnus) viscidiflora, Hook. 



Hab. Fort Okanagan and elsewhere in the interior of Oregon. 

 [These are now properly distinguished from Linosyris of the Old 

 World, and united with Bigelovia, which becomes a very considerable 

 genus. This now becomes Bigelovia Doaglasii, Gray.] 



13. APLOPAPPUS, Cass. 



1. Aplopappus (Ericameria) resinosus (Tab. 10). 



Hab. California, on the upper waters of the Sacramento. [This 

 proves, upon re-examination, not to be Nuttall's Ericameria resinosa, 

 as was thought.] It is really a slender form of the Aplopappus (Eri- 

 cameria) Bloomeri, Gray in Proc. Am. Acad. 6, p. 541, & 7, p. 354," 

 viz. its var. angustatus. 



Plate 10. Aplopappus resinosus, melius A. Bloomeri var. angus- 

 tatus. Flowering branch. Fig. 1. A ray flower. 2. A disk flower. 

 3. A detached stamen. 4. Style of disk flower. 5. Receptacle and 

 scales of involucre. The details variously magnified. 



2. Aplopappus (Ericameria) ericoides, Hook. & Am. 



Hab. California, near San Francisco, where it abounds. — On the 

 whole it appears to be impracticable to retain Nuttall's genus Erica- 

 meria. 



3. Aplopappus (Aplodiscus) Menziesii, Torr. & Gray. 



Hab. California, bay of San Francisco. [A connecting form be- 

 tween Aplopappus and Torrey & Gray's Linosyris, referred to the 

 latter in Plantse Wrightianas. It now becomes Bigelovia (Aplodiscus) 

 Menziesii, Gray, Proc. Am. Acad. 8, p. 645.]
