Eupatorium anisopodum. Herbaceous perennial: stems terete, 
decumbent, flexuous, irregularly branched, puberulent especially near the 
nodes and under a strong lens, green or purplish tinged, 3 to 5 dm. high: 
leaves ovate or rhombic-ovate, opposite, 2 to 2.5 cm. long, 1.2 to 1.7 em, 
broad, thickish, not punctate, crenate-serrate from the broadest portion 
to the acutish apex, covered above with fine short curved hairs, slightly 
_ paler beneath and appressed-pubescent upon the veins, 3—-d-nerved, sub- 
cuneate at the base to a short petiole (5 mm. in length): bracts ovate- 
lanceolate, acute, 3 to 7 mm. long, the lower petiolate the upper sessile ; 
heads small, 25-30-flowered, 5 to 7 mm. in diameter, not numerous, irregu- 
larly corymbose on pedicels of very unequal length ; scales of the turbi- 
nate-campanuulate involucre pluriseriate, very unequal, the outer short, 
ovate, acuminate, herbaceous, pubescent ; the inner oblong, acute, pale, 
2-3-nerved, ciliolate, sparingly pubescent or glabrous: corolla 2.2 mm. 
long, probably white, glabrous except at the limb where under a strong 
lens puberulent, the proper tube short, considerably exceeded by the 
Subcylindric scarcely ampliate throat: achenes columnar, at length black,

E. pyenocephalum, Coult. in J. Donnell Smith, Enum. Pl. Guat. ii. 94 
(1891), not Less. — Collected by H. von Tiirckheim at Santa Rosa, 
Department Baja Vera Paz, Guatemala, altitude 1,540 m., April, 1887, 
no. 1177 of Mr. J. Donnell Smith’s Guatemalan set. Type in herb. 
Gray. While possessing something the habit of HZ. pycnocephalum, Less., 
this plant is readily distinguished by its very different pluriseriate 
involucre.

cous-puberulent: leaves opposite, deltoid-ovate, acute or subcaudate,
