36. V. penTaTA (Cay.) Spreng. Herbaceous perennial, panic- 
ulately branched, 1-2 m. high or more; stem slender, usually 
sparsely strigillose or subglabrate, sometimes densely canescent- 
pilose, sometimes hispid. Leaves opposite below, alternate above, 
ovate to rhombic-ovate or rarely narrowly lanceolate, long-acumi- 
nate, from cuneate to truncate at base, tapering into the petiole, 
entire or more often serrulate or serrate, the teeth usually ap- 
pressed but sometimes longer and spreading, green above, from 
lepidote-strigillose (sparsely or densely) to densely rather softly 
pilose with incurved or subspreading hairs with glandular-tubercu- 
late bases, beneath varying from green and very sparsely strigillose 
or hispidulous to subcanescent with fine appressed hairs or densely 
and softly pilose, 3.5-12.5 cm. long, 0.9-8 em. wide; petioles nar- 
rowly margined, tuberculate-hispid or pilose, 0.6-5.5 em. long. 
Heads usually very numerous, cymosely panicled, on naked or 
minutely bracteolate often sharply angled peduncles 3-14 cm. 
long; heads 2.2-3.7 em. wide ; disk 7—(fruit)10 mm. high, 1—(fruit) 
1.4 cm. thick. Involucre 3-seriate, 5-10 mm. high, or sometimes 
longer by the elongated herbaceous tips of the phyllaries, gradu- 
ated or subequal, the phyllaries with ovate to ovate-oblong indu- 
rated costate and vittate body and shorter or often much elongated 
linear or linear-oblong herbaceous apex, loose or appressed, from 
hispidulous to subcanescently appressed-pilose. Rays 10-12,
