The species is closely related to V. angustzfolda, from which it 
is distinguished by the taller and coarser habit, the broad, flat, serrate 
leaves, the proportionately smaller and more irregular corymb, the 
arachnoid involucre, the blunt scales and the more brightly colored 
pappus. In general habit and gross appearance, so far as can be 
shown by herbarium sheets, the two are entirely distinct. It is to 
be regretted that no notes are available on its ecology, since both 
species live together in the same county. 
97. Vernonia concinna sp. nov. 
Stem apparently erect, simple, striate, green, glabrous, § dm. 
high; leaves numerous, thin, divaricate, oblong-linear or narrowly 
oblanceolate, flat, entire or with minute callous teeth, acute, nar- 
rowed to a sessile base, bright-green and glabrous above, paler 
beneath and sparsely pubescent with short white hairs, the principal 
leaves 10-12 cm. long, 0.8-1.2 cm. wide, the upper somewhat re- 
duced; inflorescence ree subumbellate, flattened, 1 dm. across, 
resembling that o . angustifolia; heads about 13-flowered, 1 
little ciliate, triangular-acute or mucronate, the inner oblong-lance- 
olate, the outer narrower, the basal slightly spreading; achenes mi- 
nutely pubescent, 3 mm. long; pappus purplish-tawny, 5-6 mm. long. 
Type: Nash 1759, from Eustis, Lake county, Florida; in the 
herbarium of Columbia University. The same collection is in the 
National Herbarium, numbered 223166. 
Vernonia concinna is also closely related to V. angustifolia, as 
is shown by the shape of the involucre and character of the inflor- 
escence, as well as by its geagraphical distribution. It is abun- 
dantly different in the smooth, flat, lax leaves and the acute scales. 
Some forms of the latter species resemble V’. concénna in the shape 
of the leaves, such as Harle & Baker 1777 already mentioned, but 
they invariably have acuminate scales and scabrous leaves, some or 
all of which are revolute.
