NEW OR NOTEWORTHY SPECIES. 45 
SILPHIUM INcIsuM. Stem 2 feet high, rather slender, with 
a few pairs of reduced opposite leaves; the principal foliage 
radical and large, with elongated-ovate blade 6 or 8 inches 
long (the hirsute petioles nearly as long), coarsely and in- 
cisely though not deeply toothed, sparsely strigose-hispid- 
ulous on both faces; cauline leaves lanceolate, incise-toothed, 
the lower pairs petiolate, the upper sessile: heads in a naked- 
peduncled cyme; involueral bracts oval to ovate, glabrous, 
ciliolate: achenes oval, narrowly winged marginally, but 
the wings abruptly produced at summit into a pair of broadly 
subulate teeth half as long as the body of the achene and 
forming a deep obtusely triangular notch. 
Peculiar species, known to me in a single, but very good 
specimen, preserved in the U.S. Herbarium ; collected near 
Rome, Georgia, July, 1888, by Gerald McCarthy.

PHYLA. 
Loureiro, Fl. Cochin. 66 (1790). Zapania, Lam. i. 58, t. 17 
(1791). Platonia, Rafinesque, N.Y. Med. Repos. v. 352 (1808), 
and Piarimula of the same, Fl. T'ellur. ii. 102 (1836). Species 
of Verbena, with Linnsus and pre-Linnsan authors; of 
Blairia, Geertner; of Lippia, Michx., and many more recent 
works. 
The type of this genus, known for a century or more be- 
fore Linnzeus as Verbena nodiflora, was retained in the Species 
Plantarum under that name. In general aspect the plant is 
more like certain species of Verbena than anything else; but 
this superficial likeness is deceptive. The simplest exami- 
nation of its inflorescence and fruit discloses characters in- 
dicative ofa much nearer affinity to Lantana and Lippia, these 
two representing a verbenaceous type very far removed from 
Verbena itself; for the group of which the last-named is
