TROPICAL AMERICAN EUPATORLEAE 65 
As now interpreted, this plant, clearly abundant in western Bolivia 
and adjacent Peru, although nearly related to the Chilean E. glecho- 
nophyllum Less., differs in having slightly larger heads and a peculiar 
incurved and for the most part non-glandular puberulence. The 
leaves are also of a firmer texture. In E. glechonophyllum the in- 
florescence is closely puberulent with very short straight gland-tipped 
hairs and the leaves are thinly membranaceous. Absolutely authen- 
tic material of E. azangaroense has not been available for examination. 
The extension of this species to Santa Marta, Colombia, has not been 
verified. :

Vernacular name (ace. to Mrs. Bandelier) patairuani. 
Here probably belongs E. heptanthum Rusby, Bull. N. Y. Bot. 
Gard. iv. 378 (1907), not Sch.-Bip. Its type, Bang, no. 2037 (N. Y.), 
immature and insect-damaged, has some of its leaves decidedly cor- 
date, but in other respects it appears to agree closely with E. Stern- 
bergianum. 
49. E. longipetiolatum Sch.-Bip. Bushy shrub, 2-2.5 m. high; 
stems’ terete, stoutish, flexuous, pithy, pale-brown, tomentellous; 
internodes 1-7 cm. long; branches spreading and curved, leafy 
chiefly toward the tip; leaves opposite, deltoid-ovate, crenate-ser- 
rate except near the acuminate apex and broad rounded base, firmly 
membranaceous or subcoriaceous, 3-nerved from a point 8-18 mm. 
above the base, pale-green and puberulent above, grayish-tomentu- 
lose beneath; petioles of the cauline leaves 4-7 cm. long, of the 
rameal often only 1-2 em. in length; corymbs compound, terminal, 
strongly convex, together forming a leafy-bracted panicle 1.5-3 dm. 
high and thick; heads 16~-24-flowered, about 8-9 mm. high, 6-8 mm. 
in diameter; involucre turbinate, scarcely half the length of the head, 
little imbricated; scales long-lanceolate, acutish, sordid-tomentellous, 
obscurely 1-nerved or without visible nerving; corollas purple, 4-5 
mm. long, gradually enlarged from the base to the top and without 
sharply marked throat, smooth; achenes 2.2 mm. long, covered with
