480 PROCEEDINGS OP THE AMERICAN ACADEMY. 



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

 16 June, 1887, no. 2277. 



Eapatorium Liebmannii^ 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 Prodromus 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-nervetl, thin, dark green and strigillose (under a lens) 

 above, paler and tomentulose especially upon the veins and veinlets 

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

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

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

 pyramidal j5anicle ; its branchlets, slender pedicels, and filiform bracts 

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

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

 covered 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, 

 1.5 mm. long. — Collected by C. G. Pringle in Taraasopo Canon, San 

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

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

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

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

 E. longifolium they are deeply cordate. E. Jilicaule, Sch. Bip., is also a 

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

 not the case here. 



Eupatorium luciduji, Ort. Hort. Matr. Dec. 35 (1797). An ex- 

 amination of authentic material of this briefly characterized species 

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

 name E. capnoresbium, Proc. Am. Acad. xxxv. 331, a name which must 

 accordingly sink into synonymy. 



Eupatorium. Luxii. Apparently shrubby : branches subterete, stri- 

 ate, covered with a fine spreading and very dark pubescence : leaves 

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

 at each end, pinnately nerved, 6 to 13 cm. long, half as broad, serrate,
