\\h. Chrysothamnus parryi bolanderi (Gray).- — Plant a "low shrub"; stems erect, 

 probably from a much-branched bushy base; leaves 3 to 4 cm. long, 4 to 5 mm. wide, 

 many 3-nerved, green, somewhat viscidulous, the uppermost little reduced but not exceed- 

 ing the inflorescence; heads crowded in short racemes which are sometimes branched, the 

 inflorescence then appearing cymose; involucre 9 to 10 mm. high; bracts about 11 to 15, 

 obscurely ranked, not strongly keeled, thin, with straight attenuate tips; flowers 8 to 11 

 (or as low as 7 according to Gray). {Linosyris bolanderi Gray, Proc. Am. Acad. 7:354, 

 1868.) Known only from the type locality. Type locality, Mono Pass, California, at 

 2,750 to 3,050 m. altitude. Collections: Type collection, 1866, Bolander 6137 (Gr, UC); 

 same locality, 1867, Rattan (DS, in part). 



lie. Chrysothamnus parryi latior, subsp. nov. — Plant about 4 dm. high; stems 

 erect or ascending; leaves elliptic or oblanceolate, acute, mucronate, tapering to a narrow 

 petiole-like base, 2.5 to 4 cm. long, 4 to 8 mm. wide, rigid, 1-nerved, the nerve impressed 

 above but prominent beneath, sometimes an additional pair of nerves from base of leaf, 

 but these soon disappearing, surface dull green, sprinkled with microscopic glandular 

 dots, also obscurely puberulent, the uppermost much shorter than the inflorescence; 

 heads in narrow terminal raceme-like panicles, interspersed with a few reduced leaves 

 (panicle 5 to 15 cm. long); involucre cylindric-turbinate, 12 to 14 mm. high; bracts 11 to 

 15, in 5 indistinct vertical ranks, 1-nerved, lanceolate, attenuate to rigid pungent straight 

 or only recurved-spreading tips, the short outer ones keeled, all chartaceous and nearly 

 glabrous; flowers 5 to 7, corolla tubular-funnelform, 11 mm. long, sparsely puberulent 

 on the tube; lobes about 2.5 mm. long, lanceolate, erect or only slightly divergent, sparsely 

 villous at apex in the bud; anther- tips lanceolate, acute, nearly 1 mm. long; style-branches 

 about 5.5 mm. long, the subulate appendage moderately exceeding the stigmatic portion; 

 achenes tapering to the base, 4-angled, densely appressed- villous ; pappus slightly exceed- 

 ing the corolla, rather soft, tawny to ferruginous. Known only from the mountains of 

 northern California. Collections: Wagon Creek, at the foot of Mount Eddy, Siskiyou 

 County, California, at an altitude of about 1,140 m., August 26, 1915, A. A. Heller 12250 

 (SF, type, duplicates at DS, Gr, UC); same locality, August 30, 1912, Eastwood 2079 

 (SF, UC); Little Hot Springs Valley, Modoc County, August 18, 1899, Baker (UC); in 

 dry brush at Sisson, south base of Mount Shasta, at between 900 and 1,250 m. altitude, 

 September, 1902, Grant 5162 (UC); Mount Shasta, Canby 111 (Gr, US). 



The above description of latior was drawn from the type specimen. The Eastwood 

 specimen is in close agreement and may indeed have been taken from the same or a 

 neighboring plant. Its flowers are older and the villous pubescence of the corolla-lobes 

 is therefore less noticeable. The corollas in the Baker specimen from Modoc County are 

 not fully opened. The corolla and its parts are smaller than given in the description, 

 but the lobes are very noticeably villous. Grant's collection from Sisson has some heads 

 with well-matured achenes and some with flowers only in bud. These latter are scarcely 

 if at all villous on the lobes. The corollas are 10 mm. long and the lobes about 2 mm.
