not unlike the narrow upper leaves of the typical form. Auburn, 
Alabama, Harle & Baker 769, 7 
. Leaves very broadly elliptic or ovate, narrowed below, 
ae and coarsely serrate throughout, 8-9 cm. long, 4-5 cm. 
wide; the inner scales of the involucre often nearly acute. Auburn, 
Alabama, Farle; Farle & Baker 14178. 
4. Leaves narrowly elliptic, acuminate, narrowed at base, sharply 
serrate with low teeth, scabrous above, more or less pubescent 
below, especially on the veins, 5-10 cm. long, 2-3 cm. wide; in- 
florescence large, very lax and irregular. Lee county, Georgia,

Inasmuch as V. ovelifolza is clearly related to V. altissima and 
to V. flaccidifolza, the typical form of the species, as here defined, 
is not that represented by the nomenclatorial type from Florida, but 
rather the fourth form described, growing in eastern Alabama and 
western Georgia.

Erect, 8-15 dm. high; stem glabrous; leaves lanceolate to ovate, 
acuminate, narrowed at the base into a margined petiole, sharply 
and saliently aiee essentially glabrous on both sides; inflores- 
cence flattened, loose, 1-3 dm. wide; heads about 21-flowered; in- 
volucre aia 3.5-4 mm. high; scales all appressed, regu- 
ularly imbricated, glabrous, oblong-ovate, greenish or with a purple 
spot at the obtuse or subacute tip; pappus tawny, 6 mm. long. 
Type locality: ‘* On wooded hillsides, Ringgold, Georgia.” 
Distribution: the lower Appalachian region of Tennessee, South 
Carolina, Georgia and Alabama. 
Related on the one side to V. ovadéfolza and on the other to V. 
altissima, V. flacctdifolia is distinguished from either by its short, 
hemispheric involucre with glabrous, purple-tipped scales. It is 
without doubt the most definitely characterized species of the south- 
eastern states, and is just as distinct from related forms as is V. 
Lindheimert of the southwest.
