gradually tapering to a petiole below; scales of the involucre rather hard, 
acute, with distinct midribs, roughly pubescent; pappus of short scales 
and 4—5 upwardly barbed awns; achenium linear, with five ciliolate angles. 
Corolla narrowly tubular—Sanoita Valley, Arizona (607). So far as any 
mere description goes, this plant answers better to S. serrata, Cav. in Prod. v, 
p- 118, than to canescens. However, as it has been compared for me by 
Professor Gray, I cannot doubt it is correctly placed under the latter name. 
732, from Mount Graham, Arizona, at an altitude of 9,000 feet, appears to 
be a distinct species (probably new), with broader, shorter leaves, less 
attenuated at base, with an expanded tube to the corolla, larger scales in 
the pappus, and red tips to the pappus awns. Lacking proper means of 
comparison, I provisionally refer it here. 
Eveatorium Beruanprert, DC. (Gray, Bot. Mex. Bound. p. 76, where 
its affinities are discussed).—Herbaceous, 2° high, sub-puberulent below, 
puberulent above; leaves petioled, opposite, ovate or triangular-cordate, 
crenately serrate, 1-2’ long and half as wide; flowers about 20 in a head; 
pappus not larger than the corolla; achenium very slightly scabrous on the 
angles; scales of the involucre in two series, acute and ciliolate—Sanoita 
Valley, Arizona (606).

BricKELLIA (CLAvIGERA) LoneIroLia, Watson (Amer. Naturalist, 7, 
301)—“Very slender, with spreading branches, glabrous, with a slight 
scabrousness; leaves linear, acuminate, 2-5 inches long, flat, entire or 
obscurely sinuate-toothed, rough-margined, 3-nerved, punctulate ; flowers 
on short, slender pedicels, axillary, and in small, loose, terminal clusters ; 
involucre glabrous, 2” long, the scales acutish or the inner linear ones obtuse 
or truncate, spreading ; achenium 10-striate, slightly and minutely hairy on 
the angles, nearly a line long; pappus soft, minutely barbulate, but little 
longer than the achenium—Southern Nevada. Also collected at Kanab, 
Southern Utah, by Mrs. E. P. Thomson.”—Puate V. Branch, somewhat
