TROPICAL AMERICAN EUPATORIEAE 53 
have a much looser alternate-branched inflorescence, and Kuntze 
notes the flower-color as lilac, while in E. marginatum the inflores- 
cence is opposite-branched and regular as well as considerably more 
dense, and the flower-color according to Poeppig was white. To the 
writer it would seem that the plant of Kuntze from Rio Juntas does 
not differ essentially from E. tamboense Hieron., which exhibits a 
similar flexuous habit, has an exceedingly loose somewhat alternate- 
branched inflorescence, and furthermore, is said to have lilac flowers. 
26. E. tamboense Hieron. Suffruticose, erect, 1 m. high, with 
few elongated ascending branches, nearly smooth at the base, else- 
where covered with a spreading purplish glandular puberulence; 
leaves opposite, petiolate, mostly rhombic-ovate (rarely deltoid- 
ovate or even cordate), entire toward the acute apex and abruptly 
cuneate base, elsewhere serrate (the teeth about 9 on each side), 
finely pubescent but green on both surfaces, membranaceous 3.8-5 
cm. long, about half as wide; petiole slender, 1-1.7 cm. long, finely 
spreading-pubescent; cymes loose, few-headed, together forming an 
open leafy panicle; pedicels 5-12 mm. long, densely covered with 
short spreading glandular hairs; heads 15-21-flowered, 6 mm. high, 
3 mm. in diameter; involucre campanulate, 4-5-seriate; scales about 
22, the middle and outer ovate, greenish, densely puberulent, with 
translucent margin, ciliate, obtuse, mostly 2-ribbed; the inner .ob- 
long, nearly smooth; corollas greenish- or yellowish-white, about 3 
mm. Jong, glabrous; the limb pale-lilac (Hieronymus); achenes 
dark, smooth on the faces, slightly hispidulous on the lighter-colored 
angles; pappus-bristles about 35 (20 acc. to Hieronymus), white.—
