Herbaceous, leafy, sparingly branched above, about 2 m. high, 
the stem densely strigillose. Leaves alternate, gradually reduced 
above, sessile, the lower lanceolate, acuminate, narrowed to the 
base, obscurely serrulate, 3-nerved, strigillose but scarcely scabrous 
both sides, 9-13.5 em. long, 1.7-3.1 em. wide, the upper oblong- 
lanceolate, 4-7 cm. long, 8-10 mm. broad. Peduncles bracteate, 
8-15 em. long; disk 1.2 cm. high, 1.7 em. thick. Involucre 3-4- 
seriate, graduated, the phyllaries lanceolate, acute, below indurated 
and costate, at apex herbaceous, loose, densely hispidulous and cili- 
ate, or sometimes glabrate except for the ciliolate margin. 
about 16, yellow, 1.2 em. long, 3 mm. wide; disk-corollas yellow, 
puberulous at base and apex, 4.8 mm. long. Pales somewhat wid- 
ened at apex, erose, puberulous. Achenes densely sericeous. Awns 
2, twice as long as the 4 fimbriate squamellae. — BRAZIL:

106. V. TUCUMANENSIS (H. & A.) Griseb. Herbaceous ?, more 
or less branched above, bearing 2-11 heads in a narrow cymose 
panicle; stem pale, somewhat sparsely tuberculate-strigillose, 
glabrate below except for the persistent bases of the hairs. Leaves 
alternate, linear-lanceolate, acuminate at each end, mucronate, 
entire or very indistinctly serrulate, very slightly revolute, above 
dark green, subtuberculate-strigillose, beneath distinctly paler 
and evenly but not densely strigillose-pilosulous, the hairs longer 
along the veins (which are more or less translucent), and gland- 
dotted, 8-18 em. long, 2-9 mm. wide, 1-nerved and feather-veined, 
often with short leafy branches in their axils; petioles 1-2 mm. long. 
Heads 1.8-3.5 cm. wide, on striate strigillose peduncles slightly 
thickened below the head, 1.6-7 cm. long; disk 9-(fruit)14 mm. 
thick, 8-10 mm. high, cylindric-campanulate. Involucre 4-5- 
seriate, strongly graduated, 8-10.5 mm. high, with one or two 
bractlets at base similar to the phyllaries; outermost phyllaries 
lance-oblong, 4 mm. long, 1.4 mm. wide, the next series similar but 
longer, the 2-3 inner series gradually much longer and broader 
(up to 3.5 mm. wide), all mucronulate, very strongly indurated 
below, pale and ribbed, with shorter abruptly herbaceous more OF 
less spreading triangular tip, ciliolate on margin, otherwise nearly 
glabrous. Rays about 12, oblong, 3~4-dentate, 9 mm. long, 2.5 mm. 
wide; disk-corollas minutely strigillose chiefly below, 5 mm. long 
(tube 0.8 mm.). Pales mucronulate, sparsely hirtellous above,
