ALTAMAHA GRIT REGION OF GEORGIA 237 



NYMPHJEACEjE. 

 CASTALIA Sal., in Koenig & Sims, Ann. Bot. 2:71. 1805. 

 C. odorata (Dryand.) Woodv. & Wood in Rees Cycl. 6: — . 

 1808. Water Lily. 

 Not a typical member of our flora, because it seems to require 

 permanent stagnant water. Grows in a pine-barren pond 

 near the Altamaha Grit escarpment in screven, and in an 

 artificial pond (Heard's Pond) just within our southern 

 border in thomas. Fl. April- Aug. 

 Widely distributed in the glaciated region and coastal plain 

 of the Eastern United States, but mostly wanting in the 

 Piedmont region and mountains, or if occurring there prob- 

 ably introduced. (See Rhodora 7 178. 1905.) 



NYMPH^A L., Sp. PI. 510. 1753. 



N. fluviatilis Harper, Bull. Torrey Club 33:234-236, f.2, 1906. 

 "Bonnets." 



In slow-flowing water in small rivers and in swamps of the 

 larger rivers. In the Ogeechee near Rocky Ford and 

 Dover (also at several points north of our territory), in the 

 Ohoopee near Ohoopee and Reidsville, in the Oconee 

 swamps near Mount Vernon, in the Little Ocmulgee near 

 Lumber City, and in the Withlacoochee near Nashville. 

 Flowers in June, and doubtless also somewhat earlier and 

 later. Pretty widely distributed in South Georgia, from 

 Glascock and Crawford Counties to Mcintosh, but not yet 

 known in other states (see original description). 



N. orbiculata Small. Bull. Torrey Club 23 :i28. 1896. 



Known in our territory only from Heard's Pond in thomas 

 County, an artificial pond made by damming up an ordinary 

 branch-swamp. (1178). This happens to be the type- 

 locality, but the species is evidently not native there. (See 

 Bull. Torrey Club 30:331; 32:146. Rhodora 7: 78.) It is 

 native however not far away, in the large lime-sink ponds 

 of Decatur and Lowndes Counties (see Bull. Torrey Club 

 30:331 and errata. 1903; 31 : 14. 1904), and adjacent 

 Florida.
