Encelia STRICT A. Roots fibvous : stem simple, herbaceous, striate, 

 hispidulous, about 2 feet high : leaves opposite below, alternate 

 above, sessile, erect, somewhat appressed to the stem, oblong-ovate, 

 1-2^ inches long, truncate, rounded or subcordate at the base, acute, 

 appressed pubescent and somewhat scabrous above, finely and rather 

 soft pubescent with whitish hairs beneath, irregularly callous-serrate : 

 heads few, pedunculate, f-l^ inches broad: bracts of the involucre 

 2-3 lines high, ovate, acute, densely appressed-pubescent : rays 8-12, 

 oblong-elliptic, entire or minutely 2-3 dentate, 5-7 lines long, golden 

 yellow: achenes oblong-spatulate, 1-1 J lines in length, slightly emar- 

 ginate : pappus of two delicate awns, half as long as the achene. 

 — Grassy hills near Esperanza, 8,000 ft., August (no. 339). Near 

 E. hispida, Hemsl. (ex char.). 



Galea multiradiata. Herbaceous, erect or decumbent : stem 

 somewhat branched, hispidulous, l-'2h feet high: leaves opposite, ses- 

 sile or very short petioled, lanceolate to broadly ovate, rounded or 

 subcordate at the base, acute, serrate with a few callous-tipped teeth, 

 rough pubescent on both surfaces, the veins prominent beneath: heads 

 long-peduncled, 1-3 at the ends of the branches : involucre 3-4 lines 

 high ; its bracts green, ovate, obtuse, glabrous, ciliate, striate, the 

 outer ones a little shorter and thickened at the tip : rays 15-25, ob- 

 long-spatulate, 3-5 lines in length, 2-3-dentate, purplish white, striate : 

 bracts of the receptacle slender, acuminate, shorter than the flowers : 

 achenes black, pubescent, less than a line long, angled, narrowed at 

 the base : pappus palejB about 20, slender, setaceous, minutely dentate, 

 persistent, considerably longer than the achenes and equalling the 

 corollas. — Wooded slopes, Mt. Orizaba, 10,000 ft., August (no. 167). 

 This species is related to C. elegans, DC, but amply distinguished 

 by its pubescence, more equal involucral bracts, and the number, size, 

 and shape of the rays; also near C sabazioides, Hemsl. (ex char.), 

 but differing in the leaves and involucre. 



Tagetes linifolia. Glabrous, about a foot high : stems several 

 from a short rootstock, erect or decumbent, simple or with a few 

 branches from the woody base : leaves opposite, sometimes alternate 

 above, pinnate : leaflets 3-5 pairs, mostly opposite, narrowly linear 

 with attenuate base, very acute or shortly setaceous, entire or serrate 

 at the apex : lateral leaflets 3-6 lines, the terminal about an inch in 

 length : peduncles single, terminating the stems or branches, cylindri- 

 cal, 3-5 inches long : heads solitary : involucre oblong, narrowed at 

 the base, ^ inch high, somewhat angled, 5-toothed : rays 5, conspicu- 

 ously obcordate, light yellow, 6-8 lines in length : disk flowers 25-40,
