71. E. cHoricEpHALoweEs Robinson (p. 8). Apparently herba- 
m 
ovate, acuminate, subtruncate or shallowly and broadly cordate at 
base, serrate- or crenate-dentate (teeth unequal, rounded to subacute, 
about 10 on each side, the largest 2.5 mm. high, 5 mm. broad), mem- 
branaceous, above densely puberulent, beneath puberulent and on the 
nerves and chief veins spreading-villous, about 6 em. long, about 
4.5 em. wide, 3-nerved from the base; panicle very loose and open, 
leafy-bracted, 4 dm. high, 3 dm. in diameter, densely glandular- 
puberulent throughout; pedicels filiform, 1-2.6 em. long, naked or 
inconspicuously bracteolate; heads separate, about 7 mm. high, about 
25-30-flowered; involucre campanulate; scales subequal, narrowly 
oblong or oblanceolate, erose toward the acute scarious tip, green and 
2-3-ribbed in the middle, puberulent on the back, about 4 mm. long; 
corollas white, glabrous, the proper tube about equalling the sub- 
cylindric distinctly enlarged throat; teeth very short, 0.3 mm. in 
length; achenes light-brown, 1.8 mm. long, hispidulous on the angles, 
smooth on the concave faces; pappus-bristles about 12, whitish, mi- 
nutely scabridulous.— Amazonas: Province of Chachapoyas, Mathews 
K., phot. and fragm. Gr.). 
This species in its loose inflorescence recalls the Mexican E. chori- 
cephalum Robinson.

ing to climb, 2 m. high; stems terete, flexuous, softly and shortly 
dirty-tomentellous; leaves ovate, caudate-acuminate, cordate at 
base, 5-7-nerved, thin, puberulent above, below especially on the 
nerves grayish-pubescent, about 6 cm. long, 3 cm. wide, slightly and 
remotely toothed; petiole 1 cm. long, slender; panicle ample, pyta- 
midal, 2-4 dm. high, 1.5-2.5 dm. thick, loose, leafy-bracted; pedicels 
filiform, grayish-tomentellous; heads about 20-flowered, 7 mm. high,

oblong, obtusish but sharply mucronate, mostly about 5 mm. long; 
corollas pale greenish-yellow, tubular, slightly and gradually enlarged

Weberbauer, no. 3027 (Berl., phot. and fragm. Gr.). 
A species recalling E. solidaginoides HBK. but with larger, more 
fhumerously flowered heads, longer achenes, and various minor differ- 
ences,
