were secured which agree in every detail with the original plant collected 
by Berlandier in the Valley of Toluca, no. 1164. Our plant as well as the 
type shows the inflorescence and the scales of the involucre to be glandular- 
pubescent, a character not mentioned in De Candolle’s description, Prodr.

Eupatorium oreithales. Perennial from a horizontal root-stock : 
roots fibrous, rather stout: stems herbaceous, erect, purple, pubescent, 
5 to 6 dm. high, leafy below, nearly naked above, frequently branching 
at the base: leaves opposite, broadly ovate, obtuse or rounded at the 
apex, subtruncate or short-cuneate at the base, crenate, hirtellous on the 
upper surface, puberulent on the veins beneath, becoming essentially 
glabrous, 2 to 5 cm. long, nearly or quite as broad: petioles pubescent, 
purple, 1 to 38 em. long: heads few, disposed in loose terminal corymbs, 
about 10 mm. high, 50-60-flowered: involucral scales about  2-seriate, 
nearly equal, greenish purple, pubescent, linear-oblong, acute, ciliate, 
about 6 mm. long: corollas white, 4 to 5 mm. long, tubes slender below, 
about equalling the ampliated upper portion, the lobes pubescent on their 
outer surfaces: pappus about as long as the corolla-tube: achenes 3 mm. 
long, puberulent.— Collected by C. G. Pringle, on the Serrania de 
Ajusco, altitude 2,400 m., 28 September, 1896, no. 6563. Nearly related to 
E. Saltivarii, Schz. Bip., but readily distinguished by its broader more 
rotund and crenate leaves, and also by the nearly naked stem and longer 
petioles.

Gnaphalium linearifolium. Annual, becoming somewhat ligne 
below, herbaceous above: stems terete, white-lanate, 2 to 4 mm. in diam- 
eter, simple or branched, 7 to 10 dm. high: leaves sessile, linear-attenuate, 
1 (—3)-nerved, margin revolute, arachnoid-pubescent above, white-tomen- 
tose beneath, later becoming reflexed, 6 to 11 cm. long, about 2 mm. wie 
inflorescence corymbose: heads sessile or nearly so, 6 mm. high ; ae 
lucre about 4-seriate; scales stramineous, the outer ovate-acute, inner 
oblong-obtusish : flowers numerous, perfect flowers about ten: eats 
terete, glabrous. — Collected by C. G. Pringle, on rocky hills se

lum, DC.) ; on the Sierra de San Felipe, at an altitude of 2,150 m, 17
