CATALOGUE. 139 



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 Valle} T , 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, COO 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. 



Eupatoeium Berlandieri, 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). 



Eupatoeium purfureum, L. — Utah. 



Brickellia (Clavigera) longifolia, 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." — Plate V. Branch, somewhat 

 enlarged. Figure 1. A single head of flowers. 2. A single flower. 3.
