56. VERNONIA CORYMBIFORMIS DC. Prodr. 5: 62. 1836 
Erect shrub, divaricately branched above; stem striate, glabrous 
or puberulent; leaves ample, thin, bright-green, elliptic, 8-12 cm. 
lon - cm. wide, acute or subacuminate, entire, narrowed at 
the base, almost glabrous on both sides, prominently veined ; ea 
1-2 cm. long; upper leaves similar but smaller; inflorescence de- 
pressed- hemispheric; involucre obconic- campanulate, 8 mm. ee h; 
linear-subulate, glabrous, more or less ee with purple; imma- 
Type Toealiey and distribution: Mexico. 
To this species Mr. J. M. Greenman has referred the plant de- 
scribed above, Velson gog8&, collected in the state of Jalisco. That 
this identification is correct is by no means certain. De Candolle’s 
description of this species and the following are almost identical, 
the only points of difference being in the pubescence of the leaves, 
and the width and texture of the scales; although these differences 
are by no means striking. So far as can be decided from the de- 
scription alone the plant in question most nearly resembles V. 
corymbiformis. Yt is at once separated from V. Karwinskiana 
by the larger broader leaves and the straight subulate scales. 
57- VERNONIA Karwinsxiana DC. Prodr. 5: 62. 1836 
m. high; stem purple, glabrous to puberulent; leaves 
{, 
firm, ice to oblong, 3-10 cm. long, I. —3 cm. wide, 
scabrous above, pu ubescent beneath, at least on the veins; inflores- 
oblong, tapering to an acute or subacute tip, thin, appressed at base, 
loose and a little spreading at tip. 
Type locality and distribution: Mexico. 
Two forms of distinct leaf-habit occur. In the first the leaves 
are narrowly oblong or elliptic-oblong, tapering at both ends, and 
about five times as long as wide. In the other they are ovate-lan- 
ceolate, abruptly narrowed to an obtuse base, and about three times 
as long as wide. In involucral character they are apparently the 
same.
