grows in limited quantities on the south banks of the Yellow River, 
near McGuire's Mill, Gwinnett county, Georgia. I found it in 
company with its near relative, Comandra umbellata. 
MAGNOLIA TRIPETALA L, Sp. Pl. Ed. 2,756. 1763. 
Another species new to the flora of Georgia, apparently never 
found so far southeast of the Blue Ridge. I first encountered 
Some trees at the northern base of Stone Mountain, and later at 
several localities near the mountain. The trees are small and 
slender, and the species does not thrive as it does farther north. 
CRATAEGUS ELLIPTICA Ait. Hort. Kew. 2: 168. 1 787. 
On several occasions, while collecting between Tallulah Falls 
and Toccoa Falls and in the Nacoochee Valley in northern Georgia 
Thave observed numerous groves of Crataegus elliptica growing 
on the barren slopes of low hills, usually above streams, at alti- 
tudes varying from 1000-1 500 feet. After several seasons’ 
study of this form in the field I can see no reason for uniting it 
with Crataegus fiava as a variety, as has lately been done.* Be- 
sides characters in the habit, the leaves, the fruit and seeds, which 
Serve to separate it specifically from Crataegus flava, I find an ap- 
Parent trustworthy distinction in the bark of the trunk. The 
bark of Crataegus flava is black and in high narrow ridges, while 
that of Crataegus elliptica is a light brown and in thin broad scales. 
CRATAEGUS ROTUNDIFOLIA (Ehrh.) Borck. in Roem. Arch 1: Pt. 3, 
87. 1798. 
This species of Crataegus is very common in the southern Al- 
leghanies and extends southward almost to the Gulf of Mexico. 
In 1895 I found it throughout the southern part of Georgia, where 
its favorite situation is the low ridges in the pine barrens, where 
the different species of hardwoods abound. 
CuiFronta MONOPHYLLA (Lam.) Britton, Bull. Torr. Club, 16: 310. 
1889. 
This curious and local plant forms remarkably dense thickets 
in the swamps and districts bordering streams in the vicinity of 
the Altamaha river, especially north of Jesup, Georgia. The
