essentially sessile base, serrate, 1.8 to 1.8 cm. long, nearly as broad, 
green and sparingly pubescent above, covered beneath by a short soft 
ashy more or less deciduous pubescence, and bearing upon both surfaces 
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 white 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 H. 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 
midnerve 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- 
brous. — EZ. Tuerckheimii, Coulter, Bot. Gaz. xvi. 97 and in J. 
Smith, Enum. Pl. Guat. ii. 95, as to no. 1342, not Klatt. — Collected 
by H. von Tiirckheim at Pansamald, Depart. Alta Vera Paz, Guatemala, 
altitude 1,170 m., April, 1888, no. 1342 of Mr. John Donnell Smith’s 
sets. . Tuerckheimii, Klatt, differs 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, mucrom 
ulate-serrate, smooth, green and glabrous upon both surfaces, 1 1 
1.5 dm. long, 2 to 3 em. broad, pinnately veined from a strong mid- 
nerve: smaller branches of the rather dense thyrsoid panicle fuscous
