chotomous ; pedicels filiform, 5 mm. long ; iuvolucral bracts thin, pale 

 green, very unequal, the inner oblong, obtuse, ciliate and minutely 

 puberulent, 6 mm. long, the outer much shorter, ovate-lanceolate, acute, 

 glabrous: flowers about 16: corolla purple, 6 mm. long, considerably 

 exceeding the delicate bright white pappus: achenes glabrous, dark 

 gray, 2 mm. long. — Collected by C. G. Pringle in a wet mountain 

 canon above Cueruavaca, Mexico, altitude 2,000 m., 15 February, 1899,

E. PACACANUM, Klatt, Botanisches Beiblatt zur Leopoldina, 1895, 

 p. 3. Add syn. E. roseum, Klatt. Bull. Soc. Bot. Belg. xxxi. 194 (1892), 

 not Gard. Both of Dr. Klatt's species here mentioned rest upon 

 Pittier's no. 3324. The existence of an earlier valid E. roseum neces- 

 sitates the adoption of Dr. Klatt's second name. 



E. phoenicolepis. Stems terete, probably herbaceous, purplish 

 brown, covered with dense very short glandular sordid tomentum : leaves 

 opposite, ovate, acuminate, cordate with a narrow sinus, serrate, dull green, 

 pulverulent and sometimes bullate above, paler, tomentose and reticulate- 

 veiny beneath, 3-nerved from near the base, 5 to 7 cm. lon^, 2.4 to 4.5 

 cm. broad; petioles 1.4 to 3 cm. long; bracts similar to the leaves ex- 

 cept in their smaller size, extending up into the many-headed opposite- 

 branched round-topped panicle; heads 1 cm. in height, about 18- 

 flowered; bracts of the involucre purple, flat, striate, acutish, very 

 unequal, regularly imbricated in 4 to 5 series, the outer very short, 

 ovate, dark and dull, the inner lighter and somewhat lucid, about equal- 

 ling the flowers: corollas apparently deep purple or crimson, 5 mm. 

 long, equalling the delicate and not very copious pappus : style-branches 

 clavate; achenes 2.2 mm. long, upwardly hispidulous under a lens. — 

 Collected by E. W. Nelson between San Cristobal and Teopisca, Chiapas, 

 Mexico, 4 December, 1895, no. 3475. Types in herb. Gray and herb. 

 U. S. Nat. Museum. A species with the styles and to some extent the 

 involucre of a Brickellia but the achenes of a Eupatorium. It is most 

 nearly related to E. Bigelovii, Gray, which, however, has much more 

 acute scales and smaller leaves not cordate at the base. 



B. photinum. Glabrous up to the slightly pulverulent-puberulent 

 inflorescence, herbaceous, erect, 5 dm. high; stems terete, subsimple, 

 dark purple, with rather long internodes : leaves opposite, ovate or 

 ovate-lanceolate, 7 to 11 cm. long, 3 to 4 era. broad, caudate-attenuate, 

 serrate except near the subacute base, green, glabrous, and somewhat 

 lucid upon both surfaces, 3-nerved from near the base ; reticulate veins 

 slightly translucent; petioles purple, 1.5 to 2 cm. long: heads small,
