STUDIES IN THE COMPOSITAE. 275 
Known to me only from Indian River, Merrits’ Island, 
Florida, where it was collected 31 July, 1896, by A. H. 
Curtiss, and distributed under n. 5,730. An exceedingly 
well marked species, with villous pubescence, and leaves 
closely simulating those of catnip not only in outline and 
indentation, but also in their softness of texture and pubes- 
cence. 
An interesting though perplexing group of Eupatorium 
species exists in the herbaria under the name of E. ageratoides, 
the type of which, having. been cultivated in Europe long 
before Linnsus, and more than once figured, is not of diffi- 
cult identification. But as much can not be said of certain 
segregates proposed by different authors early in the nine- 
teenth century. Among such are E. urticefolium, Michx., 
E. Fraseri, Poir., E. ceanothifolium, Ell., and probably also 
the still earlier E. cordatum and E. odoratum of Walter. 
In efforts to identify these, and also some like early segre- 
gates of E. aromaticum, I have expended much time and toil 
within the last three years, and I trust with some measure 
of success. The results of such study may be given at 
some future day; but at present I shall offer only some 
names and definitions of species such as I am confident 
have not hitherto been published, at least in this rank. 
E. EURYBLEFOLIUM. Stem 2 to 4 feet high, sparsely dark- 
puberulent, amply leafy to the summit, floriferous branched 
from the middle, the branches with 1 or 2 pairs of reduced 
leaves; all the foliage thin, dark-green, the larger leaves 3 to 
5 inches long, on petioles of an inch, spreading or ascend- 
ing, surpassing the internodes, rather narrowly subcordate- 
ovate, acuminate, mucronulately serrate-toothed, the teeth
