306 HARPER 



In many places it occurs as a second growth (known as "old- 

 field slash-pine") in drier situations than its natural habitat. 

 Perhaps its tendency to become a weed is correlated with 

 the fact that it ranges southward to the tropics (see remarks 

 under Andropogon tener, above). 

 South Carolina to South Florida and Louisiana, in the pine- 

 barrens and coastward. Believed by some to be identical 

 with a species growing in the Bahamas, Cuba, and perhaps 

 other tropical regions. In Georgia it seems to be confined 

 to the Columbia formation, but not quite to the Lafayette.

In our territory almost confined to the swamps of creeks and 

 small rivers. Has been noted in most of the counties. Fl. 

 March-April. 

 Found in nearly all parts of the southeastern United States 

 below 1000 feet above sea-level, and northward in and near 

 the coastal plain to Delaware; but so commonly a weed in 

 old fields that its natural habitat is difficult to determine in 

 some sections.

Plate 12, fig. 2. 



Moist pine-barrens, sand-hill bogs and branch-swamps; com- 

 mon throughout, but not abundant. Noted in every county 

 except Mitchell. Fl. March-April. Invariably associated 

 with the Columbia formation, and can be found almost 

 anywhere in South Georgia, including Okefinokee Swamp 

 but excepting the lime-sink region and the sea islands. Its 

 range terminates abruptly at the fall-line. Most abundant 

 in the flat pine-barrens toward the coast. 



Norfolk County, Virginia (see Torreya 3 : 122. 1903) to central 

 and West Florida, strictly confined to the coastal plain.
