A pappus-bristle ; enlarged eight diameters. Fig. 5. The style. Fig. 6. An 

 anther ; both enlarged four diameters. (493.) 



Bkickellia miceophylla, Gray. Viscidly pubescent and glandular; 

 stems 12-18' high, much branched from a woody base ; leaves alternate, short- 

 petioled, ovate, coarsely toothed, 4-7" long, those of the branchlets much 

 smaller and sessile; heads small, 15-20-flowered, clustered at the ends of the 

 branchlets ; involucral scales imbricated in many rows, outer ones ovate, her- 

 baceous, with squarrose tips, inner ones erect, lanceolate, acute; pappus 

 scabrous; achenia shghtly setulose.— Oregon, on the Walla- Walla, Nuttall. 

 East Humboldt Mountains, Nevada, and mouth of American Fork Canon, 

 Utah ; on rocks at about 6,000 feet elevation ; July, August. (494.) 



Bkickellia Califoknica, Grray. Scurfy-puberulent ; stems numerous 

 from a woody base, 14° high, branching ; leaves 9-20" long, thickish, alter- 

 nate, petioled, deltoid-ovate or subcordate, acutish, dentate, obscurely 3-nerved 

 from the base, the under surface reticulated ; heads medium-sized, nearly 

 sessile in short axillary racemes, 10-12-flowered, (about 20-flowered, T. 8^- O. ;) 

 involucral scales imbricated, obtuse, the outer ones appressed, very short, 

 inner ones erect, elongated ; achenia minute, finely pubescent, obscurely stri- 

 ate; pappus scabrous. — B. tenera and, perhaps, some other New Mexican 

 forms will probably be reduced to this species. The appressed scales and 

 larger leaves easily distinguish it from the last. California to New Mexico. 

 Robert's Station, Nevada; City of Rocks, Southern Idaho, and mouth of 

 American Fork Canon, Utah; 5-6,000 feet elevation; July-October. All 

 but the Idaho specimens are immature. (495.) 



Bkickellia gkandiflora, Nutt. Stem 2-2^° high, rather stout ; leaves 

 opposite or alternate, long-petioled, cordate-triangular, about 2' long, acumi- 

 nate, coarsely serrate, glabrous or slightly pubescent, often resinous-dotted 

 beneath ; heads middle-sized to very large, short-peduncled, clustered at the 

 ends of the panicled or sometimes corymbose branches, about 30-flowered ; 

 involucral scales much imbricated, outer scales herbaceous, ovate with long 

 subulate spreading tips, inner ones elliptical, acute, with scarioug margins ; 

 achenia sparingly setulose toward the summit. — Colorado and New Mexico to 

 Oregon and California. East Humboldt Mountains and in the Wahsatch ; 

 6-8,000 feet elevation ; August. (496.)
