graduated, 2-ribbed and 3-nerved, the inner stramineous, acutish, tawny- 
tomentellous toward the tip, the outer oblong, round-tipped, subher- 
baceous, dorsally tawny-tomentellous; corollas slenderly tubular, 
without evident throat, glabrous, 5.5 mm. long; achenes 2.8 mm. long, 
slender, tapering downward, fuscous, upwardly setulose toward the 
summit; pappus-bristles about 30, dull-white, nearly smooth, almost 
equalling the corolla.— Ann. Naturh. Hofmus. Vienna, ix. 356 (1894).

This is one of several widely different plants included by Baker under 
E. sordescens DC., which in its typical form is a pretty well marked 
species of Atlantic Brazil with much smaller (about 25-flowered) heads, 
linear and acute involucral scales, and petioles (as stated by DeCandolle) 
18-2 cm. long. The real E. sordescens seems to be well represented 
by Riedel’s no. 1348 (Gr.) determined by Schultz-Bipontinus. 
31. E. qenianruirot1um HBK. Shrubby; branches opposite, round, 
dark-hispid; internodes 4-6 cm. long; leaves opposite, ovate, narrowed 
from below the middle to an acute point, serrate except toward the 
abruptly pointed base (teeth 1-1.7 mm. high, 4-6 mm. wide, mostly 
acute), feather-veined, membranaceous, above scabrid, beneath hispid 
with minute hairs and closely beset with orange-colored glands, 
the largest leaves about 12 em. long, 5 cm. wide; petiole subterete, 
densely hispid, canaliculate above, 7-10 mm. long; inflorescence a 
trifid very leafy flattish panicle; heads pedicellate, about 10-flowered, 
8 mm. high; involucre campanulate-cylindric, the scales about 16, 
imbricated, but not very strongly or regularly graduated, the mner 
oblong-linear, smoothish, obtuse, the outer somewhat shorter, oblong, 
acutish, hispidulous—— Nov. Gen. et Spec. iv. 127 (1820).— Prura: 
near Ayavaca, Humboldt & Bonpland (Par., phot. Gr.). 
From the photograph in the Gray Herbarium this species appears 
to resemble in habit the variable E. inulaefolium HBK. The leaves, 
however, appear to be more regularly feather-veined, the petiole more 
sharply defined, and the inflorescence more leafy. From the original 
Tacter it is to be inferred that the pubescence is more hispid and of 
darker color. ‘The type-material is immature and until rediscovery the 
Status of this species must probably remain doubtful. 
32. E.vesrrrum Poepp. Erect shrub with terete somewhat flexuous 
leafy branches; pubescence on younger axes, as well as on the midrib 
and chief veins of the leaves short, dense, rusty-velvety; leaves petiolate,
