Herbaceous, erect, scarcely branched below the inflorescence, 
0.6—-2 m. high, the stem purplish, striatulate, below sparsely above 
more densely tuberculate-strigose-pilose. Leaves alternate, lance- 
olate to oblong-lanceolate, acuminate, mucronate, at base cuneate 
or rounded-cuneate, regularly serrulate (teeth 5-10 pairs, de- 
pressed, subremote) or subentire, above green, tuberculate-strigil- 
lose, beneath scarcely paler, subsparsely hispidulous, along the 
veins tuberculate-hispidulous, and gland-dotted, 6-9.2 cm. long, 
1-1.9 em. wide; petioles tuberculate-strigose and hispid-ciliate, 
1.5-2.5 mm. long. Heads about 6-9, irregularly cymose-panicled, 
44.5 em. wide, on peduncles 0.5-4 cm. long and densely tuber- 
culate-strigose; disk 11—(fruit)12 mm. high, 12-(fruit)15 mm. 
thick. Involucre 3-seriate, graduated, about 6 mm. high, the 
phyllaries oblong-lanceolate, acute to subacuminate, mucronulate, 
more or less tuberculate-strigillose and strigose, not hispid-ciliate, 
at base indurated, costate, and subglabrate, above herbaceous, 
patent or strongly reflexed. Rays 12, yellow, puberulous and 
gland-dotted on back, 1.6-2 cm. long, 4-6 mm. wide; disk-corollas 
yellow, strigillose below and on the teeth, 4.2 mm. long (tube 
0.7 mm.). Pales subobtuse, mucronulate, strigillose at extreme 
apex, 6.5 mm. long. Achenes black, sericeous, 3 mm. long, 1.1 mm. 
wide. Awns 2, slender, ciliate, unequal, 2-2.8 mm. long; squa- 
mellae about 6, fimbriate, free, 0.3 mm. long. — BOLIVIA:
