SEGREGATES OF RHUS. 129 
veins and the margin; terminal leaflet cuneate-obovate, acute, 
24 inches long, 14 wide, acute at apex, subserrate-crenate above 
the middle; laterals similar, half as large: fruits of middle 
size, granular, hirsutulous but rather thinly so. 
A shrub of middle Georgia, collected by Harper, Ashe and 
others; the type here described being Mr. Harper’s n. 1329 as 
in U. S. Herb., said to inhabit dry woods. It is the only mem- 
ber of the genus on the Atlantic slope which answers to Miller’s 
Toxtcodendron crenatum and Aiton’s Rhus suaveolens by being 
glabrous and its herbage of a sweet odor. Miller, by the way, 
compares its fragrance to that of orange peel. 
In Catesby’s time and later Miller imported plants from the 
Carolinas and Georgia, and not only from the coastal plain but 
from the mountains of the interior. His sweet sumach, it is 
practically certain, must have been this A. suaveolens, Ait. so 
long suppressed. 
S. AROMATICA (Ait.), Small, Fl. This type species of the 
genus was imported into the Kew Garden in 1772, from Carolina, 
through Bartram’s agency. It is said by Aiton to be distin- 
guished from the above by broader leaflets that are not glabrous 
but somewhat pilose. Quite such a shrub is more or less com- 
mon all the way from Alabama to Maryland, over which terri- 
tory it may prove to run into several more or less perfectly 
defined subspecies ; but all I here wish to indicate is, the impor- 
tant fact that both the Aitonian species are southern, even Caro- 
linian. 
It may be well to say at this point, that Marshall’s Rhus 
Canadensis is not referable to either of the above. It may be 
one of the next subjoined species; but it is not possible to 
identify it, no pretense even to a specific character having been 
given by that author. We are told it is Canadian, and that is 
all. 
S. SERRATA. Branches and twigs, even when young and 
growing, glabrous as in S. crenata: petioles pubescent on the 
upper side, as well as both faces of the foliage at all stages, the 
LEAFLETS, Vou. I, pp. 129-144. Nov. 29, 1905.
