Zucc, to which doubtless it has often been referred; but its 

 pappus refers it at once to EuAGERATUM and near to A. cony- 





oides L., from wKich 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, muticiim Grise- 

 bach, and which probably represents a form intermediate be- 

 tween A. muticimi and A, conyzoides. 



Stevia NEPETAEFOLIA HBK.(?)— Ojo de Agua, Depart 

 SantaRosa, alt, 3,500", September 1892, Heyde & Lnx 3,780. 

 The plant is evidently this species, but the leaves are less 

 strongly toothed and less pubescent than in the usual form. 



EUPATORIUM Ehrenbergii Hemsley. — Santa Rosa, De- 

 part. Santa Rosa, alt. 3-4,000**, March 1892, Heyde & Lux 

 ZA^7' A species closely related to E, Benthamii Klatt and 

 E. septuplinervium Klatt, but those species have much more 

 numerous flowers. Our specimens differ from Klatfs descrip- 

 tion of Hebeclinujft Ehrenhergii Sch. Bip. (Flora, 1885, 202) 

 in ha.ving about twenty-five flowers instead 6f 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. — ^Jumaytepcque,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 {Fendler) to Orizaba, Mexlco. A 

 closely allied species in Chihuahua is E. Pal^neri Gray. A char- 

 acter not mentioned by Dn 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 E. jilicaule^ 

 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 1. c. 27: 170. 



Eupatorium griseum, n. sp. Whole plant (includingboth 



leaf surfaces) hirsutely and somewhat glandular pubescent, 

 giving 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 lO™ long
