46. E. tevcopnyttum HBK. Distinctly shrubby, the stems, 
spreading-ascending terete branches, inflorescence, and under-surface 
of leaves closely white-woolly; leaves opposite, narrowly ovate, atten- 
uate, acutish, crenulate, 3-nerved essentially from the rounded to 
subtruncate entire base, pale-green and very finely puberulent above, 
white-tomentose but with perceptibly darker nerves and reticulated 
veins beneath, 3-5 cm. long, half as wide; petiole about 1 cm. long; 
heads about 10-flowered, 5 mm. long, very numerous in rounded intri- 
cately branched corymbiform terminal panicles; involucre subeyl- 
indric-campanulate; the scales about 15, narrowly oblong, obtuse, 
very unequal, dorsally white-woolly, often with a single perceptible 
mid-nerve; corollas glabrate, 2 mm. long; proper tube shorter than 
the gradually enlarged throat; achenes glabrous, shining, 1.7 mm. 
long; pappus-bristles, whitish, essentially smooth.— Nov. Gen. et 
Spee. iv. 115 (1820); Benth. Pl. Hartw. 185 (1844); Jameson, Pl. 
Aeq. ii. 82 (1865).— Although generally attributed to Peru and wi 
scarcely a doubt extending into the northern part of the country, 
this plant seems never to have been collected south of the present 
boundary of Ecuador, the only collections known to the writer being 
in favored spots of the temperate region of the Andes near the villages 
Cajanuma and Gonzanama, alt. 1976 m.,- Humboldt & Bonpland 
(Par., phot. Gr.), and in mountains of Loja, Hartweg, no. 756. moa 
latter collection (though unnumbered) there is a specimen I 
herbarium of the New York Botanical Garden. 
This species was by oversight omitted from t 
of the Eupatoriums of Ecuador. It is closely rel 
but may be distinguished by its more attenuate leaves whi vet 
and finely pulsescent above instead of being green, glabrous, and se 
as in E. niveum. In E. leucophyllum the involucral scales are pees 
narrower, more densely tomentose, and less scarious than 1m E. re 
E. leucophyllum furthermore gives the impression of being rather 
more xerophytic of the two. ‘
