71. E. CHORICEPHALOIDES Robinson (p. 8). Apparently herba- 

 ceous (the base unknown); stems and branches terete, flexuous, 

 densely puberulent, with short brownish gland-tipped spreading 

 hairs; internodes sometimes 1 dm. long; leaves opposite, deltoid- 

 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-^'illous, about 6 cm. long, about 



'4.5 cm. wide, 3-nerved from the base; panicle very loose and open, 

 leaf y-br acted, 4 dm. high, 3 dm. in diameter, densely glandular- 

 puberulent throughout; pedicels filiform, 1-2.6 cm. 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 w^hite, 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. 



72. E. FLEXILE Robinson (p. 14). Suffruticose, slender, tend- 

 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, pyra- 

 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, 

 6 mm. in diameter; involucre campanulate; scales about 16, linear- 

 oblong, obtusish but sharply mucronate, mostly about 5 mm. long; 

 corollas pale greenish-yellow, tubular, slightly and gradually enlarged 

 upward; achenes grayish, 2.7 mm. long, hispid on the angles; pappus- 

 bristles about 32, white, scarcely barbellate, about equalling the 

 corolla. — Ancachs: in woods near a river at Caraz, alt. 2200 m.. Dr. 

 Weberbauer, no. 3027 (Berk, phot, and fragm. Gr.). 



A species recalling E. soUdaginoides HBK. but with larger, more 

 numerously flowered heads, longer achenes, and various minor differ- 

 ences.
