one or more of the preceding characters, but the general habit of 
the plants, coupled with their distribution, clearly indicates their 
relationship. All are coastai-plain species of the southern Atlantic 
coast of the United States, except one endemic in the Bahamas. 
95. VERNONIA ANGUSTIFOLIA Michx. Fl. Bor. Am. 2: 94. 1803 
Chrysocoma graminifolta Walt. Fl. Car. 196. 1788. 
Vernonia graminifolia Mohr, Contrib. U. S. Nat. Herb. 6: 759. 
1901. 
Erect, 5-10 dm. high, simple to the inflorescence; stem striate, 
glabrous, pubescent or short-hirsute ; spite crowded, all narrowly 
near, 5-10 cm. long, with revolute margins, scabrous above, 
sparing'y pubescent bene ; inflorescence ample, rather compactly 
many-headed; involucre campanulate, 6 mm. high; scales gla- 
brous or ciliate, lance-ovate, reddish or purple, appressed or the 
short-acuminate tips slightly spreading; achenes 2-3 mm. long, 
furrowed, pubescent; pappus purplish. 
Type locality: ‘‘in aridis apricis sylvarum Carolinae.” 
Distribution: North Carolina, South Carolina, Georgia, Ala- 
bama, Florida, Mississippi. 
There is considerable variation in foliage and involucre among 
the specimens examine Biltmore 3669° has a narrowly cylindric 
involucre and tawny pappus, but is otherwise like the type. Zarle 
@ Earle 98 from Auburn, Alabama, has the lower leaves flat, over 
a centimeter wide and saliently toothed. The upper leaves are lin- 
ear and revolute. Others from the same place, like Earle ¢& 
Baker rr7z, have lanceolate or narrowly elliptic, entire leaves, 
sometimes I cm. across. They are a little revolute, and since the 
plant differs from the type in no other way it may be regarded as 
a mesophytic or shade form of the species. 
Although the oldest specific name for the species is Walter’s 
graminifolia, the use of the binomial V. graminifolza Mohr is 
antedated by V. graminifolia Gardner, applied in 1847 to a Bra- 
zilian species. 
96. Vernonia dissimilis sp. nov. 
Stem stout, thick, erect, 8-11 dm. high, strone ly striate, gla- 
brous above, pubescent or short-hirsute below; leaves numerous, 
pe oe or ascending, sessile, narrowly lanceolate, 10-15 
—2 cm. e, acuminate oth ends, sharply serrate, 
Tse 
pubescent with short white hairs beneath, pinnately veined with 
conspicuous lateral veinlets; upper leaves gradually reduced in size,
