GLEASON — BOLIVIAN SPECIES OF VERNONIA 
303 
species at once. It should be noted that Hieronymus’ statement that the 
leaves are 1.5 cm. wide is probably a misprint for 1.5 dm. 
Mapiri, Buchtien 1527; above Corendo, White qii; cataracts of the 
Bopi River, Rusby 488; Mapiri, Williams 713 (type of V. digitata).

V. breviramosa Rusby, Bull. N. Y. Bot. G^rd. 8: 123. 1912. 
Material identified as V. cincta Griseb. by Hieronymus can not be 
separated specifically from this common and widely distributed species.

Involucral scales lance-subulate; involucre barely exceeding 10 mm. in 
height, the common peduncle prolonged 1-2 dm. above the leaves. 
Involucral scales broad and obtuse; involucre mostly about 15 mm. 
high. 
Heads solitary or rarely 2 or 3; leaves narrowed to the base, not 
softly tomentose beneath; involucral scales nearly glabrous. 
Leaves linear, long-acuminate, minutely puberulent and con¬ 
spicuously glandular beneath. 
Leaves oblanceolate, obtuse or barely acute, prominently 
reticulate-veined, closely gray-tomentulose beneath. 
Heads several, closely glomerate; leaves rounded at the base, 
oblong-lanceolate, densely and softly ferruginous-tomentose 
beneath; involucral scales tomentose.

27. V. Kuntzei Hieron., Engler’s Jahrb. 22: 678. 1897. 
This well-marked species differs notably from the others of the sub¬ 
section in its glomerate heads, and is referred here with considerable 
hesitation.
