3895.) Composite from Guatemala. 43 
Zucc., to which doubtless it has often been referred; but its 
pappus refers it at once to EUAGERATUM and near to A. cony- 
zotdes L., from which species it differs in general habit, 
leaves, and pappus. I have seen an unnamed West Indian 
specimen all of whose pappus scales are not awned, but whose 
other characters refer it more nearly to A. muticum Grise- 
bach, and which probably represents a form intermediate be- 
tween A. muticum and A. conyzoides. 
STEVIA NEPETAEFOLIA HBK.(?)—Ojo de Agua, Depart. 
Santa Rosa, alt. 3, 500", September 1892, Heyde & Lux 3,780. 
The plant is evidently this species, but the leaves are less 
strongly toothed and less pubescent than in the usual form. 
UPATORIUM EHRENBERGII Hemsley.—Santa Rosa, De- 
part. Santa Rosa, alt. 3-4,000%, March 1892, Heyde & Lux 
3,427. A species closely related to Z. Benthamit Klatt and 
E. septuplinervium Kliatt, but those species have much more 
numerous flowers. Our, specimens differ from Klatt’s descrip- 
tion of Hebeclinum Ehrenbergii Sch. Bip. (Flora, 1885, 202) 
in having about twenty-five flowers instead of fifty, and in the 
involucral scales being decidedly glandular tomentose, as is 
the whole inflorescence, and inclined to be obtuse, instead of 
‘‘puberulent and acuminate.” 
EUPATORIUM FILICAULE Sch. Bip.—Jumaytepeque, Depart. 
Santa Rosa, alt. 6,000", November 1892, Heyde & Lux 4,234. 
In the Gray Herbarium there are specimens of this species 
extending from Venezuela (Fenxdler) to Orizaba, Mexico. A 
closely allied species in Chihuahua is E. Palmeri Gray. Achar- 
acter not mentioned by Dr. Gray (Proc. Amer. Acad. 21: 
383) in contrasting the two species may be of service in sep- 
arating them. In E&. Palmeri the involucral scales are very 
narrow, sharply pointed and entire; while in Z£. filicaule, 
although there are similar scales, most of the scales are apt 
to be a little broader and more or less toothed at apex, some- 
times becoming blunt and with broad more or less toothed or 
incised apex. In our specimens the heads are 12-flowered. 
Characterizations of this species will be found not only in 
Proc. Amer. Acad. 21: 383, but also I. c. 27: 170. 
Eupatorium griseum, n. sp. Whole plant (including both 
leat surfaces) hirsutely and somewhat glandular pubescent, 
Stving it a grayish cast: leaves opposite, perfectly cordate 
with a somewhat acuminate apex, sharply dentate, lower sur- 
face grayer and more hirsute than the upper, 8 to 10™ long
