46. E. LEUCOPHYLLUM HBK. Distinctly shrubl)y, 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 lO-flowered, 5 mm. long, very numerous in rounded intri- 

 cately branched corymbiform terminal panicles; involucre subcyl- 

 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 

 Spec. iv. 115(1820); Benth. PI. Hartw.' 135 (1844); Jameson, PI. 

 Aeq. ii. 82 (1865). — Although generally attributed to Peru and with 

 scarcely a doubt extending into the northern part of the country, 

 this plant seems never to have been collected south of the present 

 boandary 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, Ilarfwcg, no. 756. Of the 

 latter collection (though unnumbered) there is a specimen in the 

 herbarium of the New York Botanical Garden. 



This species was by oversight omitted from the writer's recension 

 of the Eupatoriums of Ecuador. It is closely related to E. niveum 

 but may be distinguished by its more attenuate leaves which are dull 

 and finely pubescent above instead of being green, glabrous, and lucid 

 as in E. niveum. In E. leueophyllum the involucral scales are thicker, 

 narrower, more densely tomentose, and less scarious than in E. niveum. 

 E. leueophyllum. furthermore gives the impression of being rather the 

 more xerophytic of the two.
