sink region of Southwest Georgia, and A. pe datum is found in 

 rich shady woods in Clarke county, Middle Georgia. Two Poly- 

 podiums also occur, both of them evergreen. I have found P. 

 vulgare only in Clarke county, at the same place where I col- 

 lected Adiantum ft e datum, probably the extreme limit of the 

 range of both in that direction. P. ftolyftodioides, the only 

 epiphyte fern in the State, is much commoner than P. vulgare. 

 It is not always epiphytic however. In Middle Georgia it shows 

 a decided preference for rocks, though further south, where rocks 

 are scarce, it is always found on trees. In dry seasons the fronds 

 of both species curl up as if dead, but in different manners. In 

 P. ftolyftodioides the edges of the pinnae turn in slightly, the 

 frond becomes conduplicate, and the rachis curves inward. In 

 P. vulgare, on the other hand, the frond becomes involute, and 

 the rachis curves outward. 



The Ophioglossacese are represented by three species. I have 

 found Botrychiian Virginianum and B. ternatum in rich woods 

 in Clarke county, and the latter in Sumter county also. Ofthio- 

 glossum nudicaule, a species of southern range, is also reported 

 from this State. Only one Equisetum, E. robustum, has been 

 reported, but further explorations will probably reveal others of 

 this interesting family. There are two or three species of Ly co- 

 podium in Georgia, all growing in sandy bogs. L. aloftecztroides 

 is locally abundant in Sumter county, mostly in the pine-barrens. 

 L. Caroliniamwi, which at first glance might be taken for a de- 

 pauperate form of the other, grows also in Sumter county, but 

 outside of the pine-barren region. 



Selaginella aftus, representing the Selaginellacese, a pale 

 and inconspicuous little evergreen, fruiting in early summer, 

 creeps along the ground, often forming dense mats, in wet woods 

 and meadows in Clarke county. The interesting but little-known 

 Isoetacese have two representatives in Georgia, both peculiar to 

 the State. Isoetes ?nela?iosftora is known only from Stone 

 Mountain, 16 miles east of Atlanta, where it is said to grow in 

 shallow depressions on the summit. This remarkable mountain 

 is an isolated granite rock rising 600 feet above a comparatively 

 level plateau of about 1100 feet elevation. There is no other 

 mountain within 20 miles of it. Its base is about a square 

 mile in area, and it is said to be the largest mass of solid granite 

 in the world. It is almost bare of vegetation, and forms a very 

 striking feature of the landscape of Middle Georgia. Besides this
