speading pubescence of delicate white or purple-jointed attenuate 
hairs; leaves opposite, membranaceous, rhombic-ovate, obtusish to 
(the upper) attenuate at the apex, shallowly 3-7-toothed on each 
side except on the entire cuneately narrowed base, 4-8 cm. long, 
1.5-3 em. wide (often with smaller leaves from undeveloped axillary 
buds), 3-nerved from well above the base, concolorous, essentially 
sessile; corymbs terminal, trichotomous, 3-5 cm. in breadth; pedicels 
0.5-2.5 em. long, curved upward, tomentose; heads about 60-flowered; 
involucre ovoid, the scales broad, rounded and purple-bordered at 
the thin closely appressed apex, sparingly pubescent; the body of

This species is suspiciously close to the little known E. clematitis 
DC. of Peru, which, however, appears to be still more glabrous and to 
have smaller lance-oblong leaves subtruncate rather than, as here, 
rounded at base. 
12. E. mallotum Robinson. Vigorous, somewhat lignescent, 
probably tending to climb, softly tomentose or tomentellous, the 
hairs dense, short, incurved; stems terete opposite-branched; leaves 
opposite, deltoid-ovate, acuminate, entire, rounded or subtruncate 
or even slightly cordate at base, 2-3.5 em. long, 1.4-2.7 em. wide, 3- 
nerved from the very base, grayish-tomentellous above, gray- oF 
canescent-tomentose beneath; petiole densely tomentose, 3-5 mm. 
long; heads 13 mm. long 8 mm. in diameter, about 30-flowered, 
numerous, in rather dense compound flattish-topped terminal 
corymbs; pedicels 6-20 mm. long; involucre at maturity cylindrical
