C. G. Pringle on the Sierra Madre near Monterey, Nuevo Leon, Mexico, 
16 June, 1887, no. 2277. 
Eupatorium 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 Z. 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. 
Hupatorium 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 tomentulose especially upon the veins and_veinlets 
beneath, 1 to 1.2 dm. long, 4 to 5 em. 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 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, subequal, 3 mm. long, 
covered with jointed purple hairs and resinous lucid atoms; corolla 
scarcely 2 mm. long, gradually contracted toward the base, neatly 
equalled by the simple white pappus: achene dark, minutely pubescent, 
1.5 mm. long. — Collected by C. G. Pringle in Tamasopo Cafion, San 
Luis Potosi, Mexico, 28 November, 1890, no. 3372. This number was 
distributed as Z. Palmeri, 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. . Jilicaule, Sch. Bip., is “7 
nearly related species, but its heads are conspicuously racemose, which 1s 
not the case here. 
Evratorium tucipum, Ort. Hort. Matr. Dec. 85 (1797). An 
amination of authentic material of this briefly characterized species 
shows that it is just the plant to which I have recently assigned sai 
name £. capnoresbium, Proc. Am. Acad. xxxv. 331, a name which must 
accordingly sink into synonymy. : 
Eupatorium Luxii. Apparently shrubby: branches subterete, st" 
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,
