Vernonia pluvialis sp. nov. 
Apparently erect and branched only near the top, height 4 
m. or more; stem finely striate, glabrate, or thinly pubescent, 
especially above; leaves spreading, or usually ascending, firm and 
rigid, oblong-ovate to subrhomboid, broadest conspicuously above 
the middle, the principal ones 3-5 cm. long by 1.1—1.9 cm. wide, 
acute, entire and subrevolute, gradually narrowed to an obtuse 
base, minutely puberulent on both sides and glandular-punctate 
below; veins not prominent, sessile or on petioles 1-2 mm. long; 
inflorescence of several short few-headed cymes in the axils of the 
upper leaves, forming a compact leafy panicle; bracteal leaves 
barely exceeding the heads, ovate to ovate-lanceolate; heads 
crowded in clusters of 2-7, or sometimes single, sessile, not at all 
secund, 8- (rarely 5-) flowered; involucre narrowly campanulate 
or subcylindric, 5-7 mm. high, its scales puberulent, well imbri- 
cated in several ranks, the outer ovate-triangular, acute or apicu- 
late, the inner becoming oblong and slightly narrowed to an 
obtuse or rounded tip; achenes densely hirsute, not mature in the 
specimens examined; inner pappus pale brown, 4-5 mm. long on 
the immature achenes.
