ALTAMAHA GRIT REGION OF GEORGIA 289 



Virginia to central Florida and Alabama in the coastal plain, 

 but natural range and habitat unknown. Also in the West 

 Indies. 



The representation of Cyperaceae in our territory is remark- 

 able for the large number of species of Rhynchospora (27 being 

 here enumerated) , the small representation of Scirpus (only one 

 normally belonging to the region, and that rare in the natural 

 state and at the same time not a typical Scirpus), and the 

 moderate number of Carices (16 species and a variety). In these 

 respects the flora of the Altamaha Grit region probably resem- 

 bles that of the tropics more than it does that of the glaciated 

 region, which would not be the case with some other families. 



GRAMINE.E. 

 ARUNDINARIA Mx., Fl. 1: 73. 1803. Reed. 

 A. tecta (Walt.) Muhl., Gram. 191. 18 17. 



Moist pine-barrens, mostly hear branch-swamps; not common. 



IRWIN, BERRIEN (2IQj), DOOLY, COLQUITT. Fl. May. 



The species of Arundinaria are very imperfectly understood, 

 and it is not at all certain that this one is identified cor- 

 rectly, so it is scarcely worth while to attempt to give its 

 whole range. 



What may be another species occurs in some of the muddy 

 swamps and rich woods.
