4-)8 Harper: Explorations in Georgia 1904 



Smith suggests that it may be the Grand Gulf, which he finds to 

 overlap a good deal of the Cretaceous and Eocene in Alabama ; 

 but the topography is not exactly that of the Altamaha Grit, which 

 in Georgia corresponds to the Grand Gulf formation in Alabama 

 and westward. Future explorations will probably settle this point. 

 The following plants of special interest were observed In South 

 Georgia in 1 904 : 



Pellaea atropurpurea (L.) Link 



Collected on May 26 on limestone boulders in rich woods in 

 the extreme northern part of Randolph County, about a mile from 



■ 



Grier's Cave (no. 2231), making one more species common to 

 Pigeon Mountain in Northwest Georgia and the Midway Eocene 

 region of Randolph County.* The general aspect of its surround- 

 ings is much the same at both places. No other coastal plain 

 station for Pellaea seems to be known. 



PSpartixa junciformis Engelm. & Gray 



May 



+ 



just outside of the city a quantity of an unfamiHar grass, and on 

 investigating the next day 1 found it to be a Spartina {jw. 218^), 

 with slender erect stems 5 or 6 feet tall, growing in dense tufts of 

 several hundred each. Its inflorescence is most like that of S. 

 jiincifotynis, a species of the Gulf coast, but it can hardly be that 

 or any other described species. The leaves of my plant are con- 

 cave, but not involute when fresh j and there is nothing in the 

 existing descriptions of 5. junciformis to indicate that it grows in 

 such large tufts. (But probably most of these descriptions are 

 drawn entirely from herbarium specimens, as is too often the case.) 

 The habitat of my plant was very unusual for a Spartina, being a 

 sort of combination of cypress {Taxodium imhricariinii) pond and 

 pine-barren stream, though probably only a few feet above tide- 

 water. All the specimens seen were within about a hundred yards 

 of each other.
