 Carex intumescens 

 var. Fernaldii Bailey 



Carea: Asa^Grayi Bailey.) Map 563. Common, but local, in low rich woods 

 and on banks of creeks and borders of swamps. Widely distributed in the 

 state but generally not found in abundance at any one locality. It is one 

 of the most conspicuous of the sedges and so is apt to be collected more 

 often than some of the inconspicuous species which may be actually more 

 common. 



The form known as var. hispidula shows no geographic segregation and 

 doubtless does not merit even formal recognition. J. K. Underwood, of the 

 University of Tennessee Agricultural Experiment Station, writes that he 

 has observed the same plants which one year had hispidulous perigynia to 

 be perfectly glabrous the next season.

136. Carex louisianica Bailey. (Carex Halei Carey.) Map 566. A 

 southern species which reaches its northwestern limit in southern Indiana 

 where it is infrequent in low open woods, flat woods, and cypress swamps, 

 mostly in the unglaciated area. 



N. J. to Ind., southw. to Fla. and Tex. 



137. Carex lupulina Muhl. (Carex lupulina var. pedwiculata Gray.)
