Chrysopsis Brandegei. Low villous perennial, 3 to 5 inches 

 high, with spreading branched scaly rootstock and numerous densely 

 tufted stems : leaves spatulate, entire, gradually narrowed below into 

 slender petioles, rounded at the summit but mucrouate-acuminate at the 

 very apex, 1-nerved, finely grayish-pubescent and covered with very 

 short yellowish glandular or i-esinous-tipped hairs (so short as to appear 

 when viewed from above merely as sessile globules), and spreading'villous 

 on the edges, 7 or 8 lines long including the petioles; lowest leaves 

 shorter, densely crowded at the base, and often canescent with more 

 appressed pubescence : peduncles terminal, slender, erect, flexuous, terete, 

 H to 2 inches long, villous with spreading hairs and also closely covered 

 with the minute glandular hairs, entirely leatiess but sometimes bearing 

 one or two short filiform bracts : heads solitary, discoid, 6 to 8 lines in 

 diameter, half inch in height, 40-45-flovvered : scales of the involucre 

 ver\' unequal, imbricated in about 4 series ; the outer ones very small, a 

 line in length, very villous, the inner oblong, purplish, rather abruptly 

 but acutely pointed, flat and smoothish, ciliolate on the margin, 3^- lines 

 long, half to two thirds line broad : corollas 5-toothed, golden yellow, gla- 

 brous, 4 lines long: pappus manifestly doubh, the outer bristles very un- 

 equal: stigmas sometimes 3: achenes (immature) densely silky-villous, 

 about a line long. — Chrysopsis sp., Brandegee, Zoe, iv. 206. — Collected 

 by T. S. Brandegee at San Pedro Martir, Northern Lower California, 

 May, 1893. 



Bigelowia pyramidata. Shrub, 2 to 3 feet high, much branched : 

 branches white-woolly; branchlets striate : leaves fascicled, linear-acicu- 

 lar, entire, somewhat pungent, white-woolly beneath, strongly revolute at 

 the margins, pale green and grooved above, 4 to 14 lines long, half line 

 in breadth: inflorescences terminal pyramidal panicles: heads small, 

 numerous, sessile or subsessile, spicately arranged along the spreading- 

 ascending branches, subtended by fascicles of short spreading pungent 

 leaves, discoid, few (o-7)-flowered : scales of the involucre linear-lanceo- 

 late, acute, scarious, diaphanous: flowers pale yellow, pappus scarcely 

 tawny, of numerous fine unequal bristles ; young achenes silky, the ma- 

 ture not seen. Collected by C. G. Pringle, on hills above Oaxaca, 

 altitude 5,500 feet, 16 November, 1894, no. 6048. A species anomalous 

 in its spicate-paniculate inflorescence but with the other characters of 

 Bigeloivia.
