STUDIES IN THE COMPOSITE. 279 
purple-dotted or -streaked : leaves numerous, about equalling 
the internodes, 1 to 2 inches long, divaricately spreading or 
somewhat deflexed, of very firm texture, scabrous above, 
minutely rough-pubescent along the veins beneath, generally 
of ovate outline with rounded or else abruptly tapering base, 
coarsely but not deeply crenate-ioothed: heads very many, 
rather loosely cymose; involucres narrow, only about 10- 
flowered, their linear bracts with long 2-striate body and 
short thin tips: corollas with slender tube and narrow- 
campanulate limb about equal: achenes glabrous, black; 
pappus very fine, scabrous. 
Seemingly a very common analogue of E. aromaticum 
along the coast of the Gulf of Mexico from western Florida 
to Louisiana, abundant specimens having been distributed 
by the late Rev. Fr. Langlois, and by Prof. S. M. Tracy; 
those of this collector being represented by his numbers 
5,056, 6,447 and 6,448. It differs from E. aromaticum, its 
correlative belonging to Virginia and regions northward, 
by its larger size, more branched and copiously floriferous 
growth, but especially by its small rigid rough foliage, 
narrower and fewer-flowered involucres, ete. I have duly 
considered the possibilities of its proving identical with E. 
cordatum Walter, a species to be restored. 
E. nknBACEUM. Æ. ageratifolium, var.? herbaceum, Gray, 
Pl Wright, ii. 74. Stems very leafy to the summit, the 
leaves large, thin, ovate-trigonous, 2 to 3 inches long, 
nearly 2 inches wide at base, acute, serrate-toothed, not 
conspicuously veiny: cymes terminal, nearly sessile, partly 
embraced by the uppermost pair of leaves, these being 
scarcely smaller than the others: bracts of involucre lanceo- 
late, in an almost double series, the outer shorter: corollas 
elongated, tubular-funnelform, scarcely exhibiting distinction
