Eupatorium Gonzalezii. Apparently herbaceous and to the unas- 

 sisted vision glabrous throughout ; stems terete, green, finely striate, 

 lucid, purple at the nodes, slender ; the younger parts microscopically 

 puberuleut : leaves opposite, long-petioled, deltoid-ovate, obtuse, coarsely 

 crenate-dentate, 3-nerved from the entire abruptly acuminate base, thin, 

 bright green and glabrous upon both surfaces, 4.5 to 7 cm. long, 4 to 

 4.0 cm. broad ; petioles slender, 3 cm. long ; the uppermost leaves ovate- 

 lanceolate, entire, shorter-petioled : heads numerous, about 18-fiowered, 

 small, in compound axillary and terminal cymes ; peduncles and pedicels 

 ascending, obscurely puberulent ; bracts spatulate and mucronate to 

 linear and acute, small ; involucral scales green, striate, narrow, linear, 

 obtuse at the scarious erose and often crumpled apex, a few of the outer 

 considerably shorter, ovate, acuminate, ciliolate : corollas white, glabrous 

 throughout, the greenish white proper tube somewhat exceeded by the 

 pure white throat aud spreading limb : achene dark, 1.3 mm. long, up- 

 wardly hispid on the angles ; pappus pure white, sparse ; the bristles 

 essentially equal, nearly as long as the corolla, slightly connate into a 

 minute cup at the base. — Collected by Professors C. Conzatti aud 

 V. Gonzalez at El Fortin, Oaxaca, altitude 1,600 m., March, 1807,

Eupatorium leonense. Stem 4 mm. in diameter, slightly lignes- 

 cent, pithy, yellowish brown, glabrate ; branches opposite, curved-as- 

 cending, striate, tomentulose, finely pubescent : leaves o^iposite, ovate to 

 deltoid-ovate, long-petioled, thin, coarsely and rather bluntly few-toothed, 

 acutish, abruptly contracted at the entire base to an acuminate attach- 

 ment to the long petiole, finely pubescent when young, nearly or quite 

 glabrate at maturity, 3 to 5 cm. long, nearly as broad, 3-nerved from a 

 little above the base; petioles 3 to 4 cm. long, pubescent: jxjdicels 

 slender, flexuous, green, puberulent ; bracts minute, subulate ; heads 

 rather few in a small round-topped panicle, medium-sized, 8 ram. long, 

 about r2-flowered ; involucre campanulate, loosely imbricated, lance- 

 linear, attenuate, very acute, green, striate, thin, sparingly white-pubes- 

 cent, the outer much shorter : corolla narrowly cylindrical, of essentially 

 uniform diameter throughout its length and without clearly marked 

 throat or proper tube, glabrous : style-branches strongly clavate, yellow ; 

 achenes black, glabrous, lucid, 2 ram. long with conspicuous yellow cal- 

 losity at the base ; pappus white, equalling the corolla. — Collected by
