332 PROCEEDINGS OF THE AMERICAN ACADEMY, 
cafions near Guadalajara, Jalisco, Mexico, 29 October, 1889, no. 2343, 
and earlier on the Rio Blanco in the same neighborhood by Dr. Edw. 
Palmer, October, 1886, no. 665. Both plants were distributed as E. 
Benthamit. However, Klatt’s species of that name (which is a clear 
synonym of the earlier #. Hhrenbergii, Hemsl.) has ovate serrate not 
cordate leaves, more numerously flowered heads, etc. 
E. CHAPALENsE, Wats., var. salicifolium. Leaves narrowly lance- 
olate, merely serrulate, acute at both ends, 4 to 6 em. long, 1.2 to 1.4 
em. broad: scales of the involucre oblanceolate, broader than in the 
typical form. — Collected by C. G. Pringle on mountains near Lake 
Chapala, Jalisco, Mexico, 18 October, 1895, no. 7071. The leaves of 
the typical form are more than 4 cm. broad. The variety retains the 
floral characters and unequal pappus of the type. 
E. chiapense. Stem terete, clothed with a dense purplish brown 
tomentum; internodes long (6 to 8 cm.): leaves opposite, ovate, 
acuminate, serrate-dentate except near the rounded base, dull green 
and except on the subpinnate nerves nearly glabrate above, paler and 
ferrugineous-tomentose upon the nerves and veins beneath, 1 to 1.4 dm. 
long, 6.5 to 8 cm. broad ; petioles densely tomentose, 4 to 5.5 cm. long: 
heads numerous, 9 mm. high, about 24-flowered, borne in a compound 
_ round-topped corymb (1.5 dm. broad); the opposite branches and 
pedicels tomentose with purple gland-tipped hairs ; involucre subsimple 
~and scarcely imbricated ; scales about 10, narrowly linear, attenuate, 
mostly 2-ribbed, 6 mm. long, pubescent: corollas glabrous, 5 mm. long, 
exceeding the dull white pappus; throat equalling the proper tube: 
achenes black, glabrous, tapering toward the base, 4 mm. long. — 
Collected by E. W. Nelson, near Pinabete, Chiapas, Mexico, altitude 
2,000 to 2,400 m., 8 February, 1896, no. 3786. This species is related 
to £. Ehrenbergii, Hemsl., but has much narrower involucral scales, 
smaller heads, glabrous corollas, ete. It is also and perhaps still more 
closely related to EZ. Donnell-Smithii, Coulter, which, however, has 
pale obtusish involucral bracts, and flowers much smaller, scarcely 
more than half as long. 
HE. crassirameum. Large shrub or small tree, 3 to 5 m. high, 
glabrous throughout : branches thick, terete, soft-woody to the inflores- 
_ ence, covered with a pale gray cortex: leaves opposite, petiolate, large; 
deltoid-ovate, thin, pellucid-punctate, glabrous, acuminate, repandly few- 
toothed at the sides, pinnately veined, becoming 1.5 dm. long and 
about equally broad ; petioles 5 em. in length: heads numerous, about 
1-fowered, pedicellate in dense rounded compound corymbs (9 cm. in
