SEGREGATES OP RHUS. 12d 



teins and the margin ; terminal leaflet cuneate-obovate, acute, 

 21 inches long, li wide, acute at apex, subserrate-crenate above 

 the middle ; laterals similar, half ae 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 

 Toxicodendron crenatum and Alton'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 R. suaveolens. Ait. so 

 long suppressed. 



8. AEOMATICA (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 Alton 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. SEREATA. 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
