Carex rugosperma sp. nov. 

 ''Carex umhellata Schkuhr," Mackenzie, Bull. Torrey Club 40: 



551- 1913- 



A careful study of Schkuhr's plate of Carex umhellata has 

 thoroughly convinced me that what he had was the plant with 

 short-beaked perigynia, named Carex ahdita by Mr. Bicknell.* 

 The plant with the long-beaked perigynia is in consequence with- 

 out a name. A specimen collected by me at Tuckerton, New 

 Jersey, in May, 191 1, and in my herbarium, maybe designated as 

 the type of the above species.
