 golden resinous particles: panicle flat-topped, its slender ascending 

 branches and pedicels (7 to 9 mm. long) grayish-tomentulose; bractlets 

 linear to filiform; heads about 12-flowered, 7 mm. long; involucral 

 scales subequal, oblong, soft-pubescent and pale green upon the outer 

 surface, 3 to 4 mm. long, obtuse : corollas vifhite or at least pale, 4 mm, 

 long, with slender tube somewhat exceeded by the gradually ampliated 

 throat, glabrous : achenes 2 lines long, hispid on the angles, pappus 

 white, equalling the corolla. — Collected by C. G. Pringle on rocky 

 hills near Guadalajara, Jalisco, 26 May, 1891, no. 3718. Distributed 

 as E. scordonioides ? a species with shrubby perennial stems, deltoid- 

 peltate leaves, etc. 



Eupatorium pansamalense. Stem glabrous, rather strongly 

 angled, striate, pithy : leaves opposite or ternate, slender-petioled, 

 rhombic-ovate, caudate-acuminate, acute at the base, mucronate-serrate, 

 thin, pinnately nerved, deep green and nearly glabrous except on the 

 miduerve above, paler and puberulent or tomentulose upon the nerves 

 and veins beneath, 1 to 1.3 dm. long, half as broad ; petioles 2 to 3 cm. 

 long : branches of the inflorescence and filiform pedicels fuscous-tomen- 

 tulose ; heads about 35-flowered, very numerous in a round corymbose 

 panicle ; scales of the involucre in about 3 series, narrowly oblong, acute 

 to acutish, in a dried state stramineous except a central dark brown streak, 

 the more or less narrowed tips thin, erose : corollas slender, without 

 definitely marked throat, glabrous except near the limb : pappus white, 

 equalling the corolla; achenes very small, scarcely 1.4 mm. long, gla-

 sets. E. Tiierchbeimii^ Klatt, difi'ers in having much narrower oblong- 

 lanceolate subcoriaceous short-petioled leaves which are quite glabrous 

 upon both sides, paler beneath, and marked by a fine transverse 

 venulation. 



Eupatorium pinabetense. Shrub with angled and striate glabrous 

 branches : leaves opposite, lance-oblong, acuminate at each end, mucron- 

 ulate-serrate, smooth, green and glabrous upon both surfaces, 1 to 

 1.5 dm. long, 2 to 3 cm. broad, pinnately veined from a strong mid- 

 nerve : smaller branches of the rather dense thyrsoid panicle fuscous-
