GREENMAN.— NEW ANGIOSPERMS FROM MEXICO, 111 
culate, 1.5 to 2 cm. high, 5 cm. in diameter: involucre about 4-seriate ; 
bracts of the involucre lance-oblong, acute to obtuse, thickish, striate, 
externally somewhat tawny pubescent and as well as the corollas and 
pales of the receptacle more or less glutinous: ray-flowers 12 to 16, con- 
spicuous: disk-flowers numerous: achenes strongly compressed laterally, 
-Sparingly hirsute-pubescent on both surfaces, long-ciliate on the mar- 
gins. — Mexico. State of Chiapas: along road from Ocuilapa to 
Tuxtla, altitude 600 to 1000 m., 29 August, 1895, H. W. Nelson, no. 807, 
(hb. Gr., and hb. U. S. Nat. Mus.). 
The affinity-of ZH. collodes seems to be with E. glutinosa, Rob. & 
Greenm., and Z. Pringlei, Fernald. From the former it is distinguished 
by the larger and fewer heads, longer involucral scales, and by the 
absence of the long sericeous hairs on the young shoots; from the latter 
it is readil y separated by the foliar characters. 
Encelia Conzattii. Perennial: stem covered with a grayish bark ; 
branches and branchlets purplish, slightly compressed particularly at the 
nodes, striate, closely and minutely appressed-strigulose : leaves opposite, 
short-petiolate, lanceolate, 5 to 10 em. long, 1 to 2.5 em. broad, acumi- 
nate, acute, remotely denticulate, narrowed below into a crisp-undulate 
base, dark green and puberulent above, pale and closely canous-pubes- 
cent beneath: inflorescence a terminal leafy subcorymbose or paniculate 
cyme: heads including the sulphur-yellow rays 2 to 2.5 cm. in diameter, 
lem. or less high, on densely canous-pubescent peduncles 0.5 to 3 cm. in 
length ; involucral scales 2—3-seriate, the outer scales subfoliaceous ; 
ray-flowers usually 6: disk-flowers about 35: achenes sparingly pubes- 
cent on both surfaces, conspicuously ciliate on the margins. — MEXICO. 
State of Oaxaca: altitude 1750 m., daly Anger, 1900, Conzatti & 
Gonzdlez, no. 1007 (hb. Gr.). 
Encelia pilosa. Annual: stem erect, purplish or stramineous, his- 
pidulous-pubescent with long pilose hairs intermixed, somewhat stipitate- 
glandular especially in the inflorescence : lower leaves opposite, petiolate, 
broadly ovate, 3 to 14 cm. long, fully two-thirds as broad, acute, suben- 
tire to crenate-dentate, hirsute-hispid above, hirtellous-pubescent beneath, 
3-nerved from the base; petioles neither winged nor auricled, usually 
bearing long pilose hairs ; upper leaves gradually reduced and shorter- 
petioled: inflorescence a many-headed nearly naked subcorymbose or 
paniculate cyme: heads radiate, 10 to 12 mm. high: scales of the invo- 
lucre imbricated in 3 to 4 series, more or less purplish colored, exter- 
nally pubescent, the outer scales ovate, acute, shorter than the inner 
lanceolate ones: ray-flowers, commonly 5; rays yellow, elliptic-oblong,
