256 HARPER 



August. Not easily distinguishable from the preceding a short 

 distance away, and certainly more closely related to it than 

 to the following species. Occurs also in the flat country. 



New Jersey to Florida (?) and Louisiana, in the coastal plain. 

 Also in Middle Tennessee (Gattinger). 

 H. nivea (Nutt.) Spreng., 1. c. (Plate XXV, Fig. i.) 



Intermediate and moist pine-barrens; not abundant, bul- 



LOCH {8^2, 954), EMANUEL, TATTNALL, MONTGOMERY, DODGE, 



telfair. Fl. June-July. Also in the Lower Oligocene 

 region in Sumter and Lee Counties, and coastward to 

 Bryan County. 

 Delaware and South Carolina to Florida, Arkansas, and Louisi- 

 ana, nearly confined to the pine-barrens. 

 BURMANNIACEjE. 

 BURMANNIA L., Sp. PI. 287. 1753. 

 B. capitata (Walt.) Mart., Nov. Gen. & Sp. PI. Bras. 1:12. 1824. 

 (See Torreya 1:34. 1901; Bull. Torrey Club 28:470. 1901.) 

 Moist pine-barrens; not rare but very inconspicuous, dodge, 



COFFEE, IRWIN, BERRIEN (66$), DOOLY, WORTH, COLQUITT, 



decatur. Fl. Aug.-Oct. Seems to reach its inland limit 

 near Cordele, at the extreme edge of our territory. 

 North Carolina to central Florida and Louisiana, in the pine- 

 barrens. Also in the West Indies and South America (if 

 the tropical plant is correctly identified). 

 B. biflora L. ought to grow in our territory, but I have never 

 seen it there. Apteria, the related genus, is known at 

 several points in the Upper Oligocene region, just south of 

 our limits. 



IRIDACE^. 

 IRIS L., Sp. PI. 38. 1753. 

 I. versicolor L., Sp. PL 39. 1753. 



Mostly in and near branch-swamps, more rarely around per- 

 manent ponds or in low woods, bulloch, tattnall, 



MONTGOMERY, DODGE, TELFAIR, COFFEE, WILCOX, BERRIEN, 



colquitt. Fl. April-May. Pretty widely distributed in 

 the pine-barrens of Georgia, but not seen in other parts 

 of the state.
