SMILAX ROTUNDIFOLIA CRENULATA Small & Heller, Mem. Torr. 
Club, 3: 17 (1892). 
Grows in similar localities at Tallulah Falls, Georgia, especi- 
ally at the bottom of the deep caiion, as in the forests on Grand- 
father Mountain, North Caroline, the original station.* The 
plants are almost identical with the type and exhibit well the 
principal characters. The lanceolate leaves and the erose-crenu- 
late margins are particularly striking. We now have this form 
from Southwestern Virginia, North Carolina and Northern Geor- 
gia, and may expect to find it at intermediate places along the 
mountains.

There exists in the valley of the Yellow River, about eighteen 
miles east of Atlanta, Georgia, a slender Ce/tis with remarkably 
small leaves and of a diffusely branched habit. In some respects 
it differs from any form yet described, but is nearest to C. rettculata 
Tor rey, a species of the Southern Rocky Mountain region. 
The specimens are so similar to that species that I consider it 
better to place it there than to describe it as new. This form 
agrees very well with Dr. Torrey’s type, differing principally in 
the smaller and acute or acuminate leaves, which do not vary 
much from an inch in length. Those of the type specimens are 
Mostly obtuse and some an inch and a half long. However, we 
have specimens almost identical with mine from Santa Cruz 
‘Valley near Tuscon, Arizona (Pringle), and cafions in the Burro 
Mountains, New Mexico (Rusby). The leaf form of the plant 
under consideration corresponds almost exactly with those collec- 
tions. 
At first I thought this form might be C. pumila, but an au- 
thentic specimen of Pursh’s plant in the Columbia College Her- 
barium shows that it is a form of C. occidentalis.

In the Silva of North America, Prof. Sargent has reéstablished 
and given us a clear conception of this good species. I have 
recently (August 11, 1893) discovered a grove of this plum in the 
foothills of the Blue Ridge between Tallulah Falls and Toccoa
