Varying from smoothish to pubescent, the hairs when present being 

 tawny and stiffish, occurring chiefly below the middle of the stem and 

 on the young branches about the base. The species is suspiciously 

 close to E. viscosum HBK., supposed to have come from Ecuador 

 (see p. 361).

 curved-ascending striate and somewhat hexagonal branches; leaves 

 opposite, petiolate, rhombic-ovate, acuminate, about 3 cm. long, 

 incisely serrate except toward the cuneately narrowed base, mem- 

 branaceous, smooth, 3-nerved and reticulate-veiny; petiole 6-8 mm. 

 long; heads numerous, about 5-flowered, in terminal flattish-topped 

 trichotomous compound corymbs; involucre short-cylindric; scales 

 about 5, narrowly oblong, blunt, sticky, ciliate but otherwise smoothish;

As yet known only from the original material of uncertain origin, 

 but doubtfully supposed by Kunth to have been collected in the place 

 cited and at an altitude of about 1000 m.

 3 m. in height (Andre); branches subteretc or obscurely hexagonal, 

 finely pubescent; internodes usually 4-10 cm. long; leaves opposite, 

 slender-petioled, o^'ate, caudate-acuminate, rounded or cordate at 

 base, dentate, thin, membranaceous, 5-12 cm. long, half as wide, 

 subglabrous or hirtellous above, sparingly to rather densely pubescent 

 beneath; petioles 1-3 cm. long; the axils often proliferous; panicle 

 terminal, leafy-bracted, pyramidal, its branches widely spreading; 

 heads small, on filiform pedicels, disposed in often subglobose glom- 

 erules on short secondary branchlets; florets 10-15, greenish- to yel- 

 lowish-white, much exserted; involucral scales about 12, subequal,
