23. V. Purpusit Brandegee. Herbaceous (?), 2.5 m. high, the 
stem greenish-fuscous, retrorsely hispid-pilose, tuberculate-stri- 
gillose and somewhat glandular-granulose, the stem and branches 
bearing mostly solitary heads. Leaves opposite below, alternate 
above, ovate or deltoid-ovate, acute to subobtuse at apex, from 
rounded to subcordate at base, shallowly repand-serrate with 
about 5-10 pairs of depressed teeth, 3-nerved, dark green above, 
scabrous, tuberculate-hispidulous and gland-dotted, beneath paler 
or nearly equally green, hispid-pilose along the veins and glandular- 
dotted between them, sometimes subcanescent, 2-7.3 cm. long, 
1.5-6.5 em. wide; petioles more or less densely hispid-pilose, (0.6) 
1-3 em. long. Peduncles 2.7-14 cm. long; heads 1.8-2.5 em. wide; 
disk 7.5-12 mm. high, 13 mm. wide. Involucre 3-seriate, 6-8.5 mm. 
high, slightly graduated, the phyllaries oblong, obtuse to subacute, 
hispid-pilose especially on margin, densely tuberculate and gland- 
dotted, somewhat indurated and ribbed below the middle, herba- 
ceous above. Rays about 12, prominulous on veins of back, 1 cm. 
long, 3 mm. wide; disk-corollas glandular-hispidulous, 5-6 mm.
