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 umhellata. 



Magnolia tripetala L. Sp. PI. 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. 1787. 



On several occasions, while collecting between Tallulah Falls 

 and Toccoa Falls and in the Nacoochee Valley in northern Georgia 

 I have observed numerous groves of Crataegus elliptua growing 

 on the barren slopes of low hills, usually above streams, at alti- 

 tudes varying from 1000-1500 feet. After several seasons' 

 study of this form in the field I can see no reason for uniting it 

 with Crataegus flava 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 i: Pt. 3, 



2>T. 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. 



Cliftonia 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
