sursum hispidis basi callosis apice cum disco parvo flavescente pappi- 
fero coronatis; pappi setis albis roseo-tinctis sursum scabridulis 
apicem versus paullulo incrassatis.—Ecuapor: vicinity of Las 
Juntas, J. N. Rose, A. Pachano, & G. Rose, no. 23,179 (Gr., U.S., 
PY}: 
This plant differs from E. pichinchense HBK. in its copiously 
gland-tipped pubescence, much smaller, fewer-toothed leaves, ete. 
From E. glanduliferum Hieron. it may be distinguished by having the 
leaves petiolate and their blades essentially as wide as long. In many 
respects it corresponds pretty closely with the Colombian E. sotarense 
Hieron., but that species, according to Hieronymus, has leaves glabres- 
cent or subglabrescent (while they are here densely and permanently 
pubescent to villous on both surfaces), rounded at the base (while 
here distinctly cordate), and longer than wide. 
E. RoRULENTUM Robinson, Proc. Am. Acad. liv. 255 (1918). This 
species, described from young material with the heads merely in bud, 
has been collected near Laguna de Verjén, Colombia, by Bro. Ariste- 
Joseph, no. B20 (Gr.). From this material, which, agreeing as to 
habit and foliage in all details with the original, is decidedly more 
mature, it is possible to add the following characters to those recorded 
in the diagnosis: heads at length 8-9 mm. high; corolla whitish 5 mm. 
long, sparsely atomiferous, proper tube 1 mm. long, the throat about 
4mm. long, the limb about 0.6 mm. long, the teeth deltoid, acutish; 
mature achenes dark brown, about 3 mm. long.
