C. G. Pringle cm the Sierra Madre near Monterey, Nuevo Leon, Mexico, 

 16 June, 1887, no. 2277. 



Eupatorium Liebmunnii, Sch. Bip. in Klatt, Leopoldina, xx. 75 

 (1884). From the characters given and from an excellent drawing (in 

 herb. Klatt) prepared from the original material I cannot avoid the conclu- 

 sion that this is identical with the earlier E. hirsutum, DC, the type of 

 which I have recently examined in the Prodroraus Herbarium. The 

 species is represented by Mr. Pringle's no. 6046 from the foothills of the 

 Sierra de San Felipe, Oaxaca. 



Eupatorium longifolium. Suffrutescent, 1 m. high : stems virgate, 

 terete, finely striate, covered by a fine spreading purplish and probably 

 viscid pubescence : leaves opposite, short-petioled, ovate-lanceolate, cre- 

 nate-serrate, 3-nerved, thin, dark green and strigillose (under a lens) 

 above, paler and tomeutulose especially upon the veins and veinlets 

 beneath, 1 to 1.2 din. long, 4 to 5 cm. broad, attenuate to a caudate 

 apex, rounded and deeply cordate at the base, the sinus narrow: inflor- 



acea rounded-corymbose, together forming a large leafy oval or sub- 

 pyramidal panicle; its branchlets, slender pedicels, and filiform bracts 

 brown-pubescent ; heads very numerous, 4 to 5 mm. long, about 10- 

 flowered ; involucral scales linear, attenuate, subeqnal, 3 mm. long, 



ered with jointed purple hairs and resinous lucid atoms: corolla 

 scarcely 2 mm. long, gradually contracted toward the base, nearly 

 equalled by the simple white pappus : achene dark, minutely pubescent, 

 1 . ■) mm. long. — Collected by C. G. Pringle in Tamasopo Canon, San 

 Luis Potosi, .Mexico, 28 November, 1890, no. 3372. This number was 

 distributed as E. Palmeri, Gray, to which it is obviously related. It 

 differs, however, both in the nature of its indnment and the form of the 

 leaves. The latter are rounded at the base in E. Palmeri while in 

 /-,'. longifolium they are deeply cordate. E. JUicaulc, Sch. Bip., is also a 

 nearly related species, but its heads are conspicuously racemose, which is 

 not the case here. 



Eupatorium lucidum, Ort. Ilort. Matr. Dec. 35 (1797). An ex- 

 amination of authentic material of this briefly characterized species 

 -hows that it is just the plant to which I have recently assigned the 

 name /•,'. Capnoresbium, Proc. Am. Acad. xxw. 331, a name which must 



rdingly sink into Bynonymy. 

 Eupatorium Luxii. Apparently shrubby : branches subterete, stri- 

 ate, covered with a line spreading and verv dark pubescence : lea\ < ■- 



opposite, elliptic-ovate (the upper ovate-lanceolate), acute to acuminate 



eh end, pinuately nerved. •'. to 13 cm. long, half as broad, serrate,
