 The President, Dr. Leidy, in the chair. 

 Twenty-four persons present. 

 The following Avere ordered to be printed : 



a list of the carices of pennsylvania. 

 By Thos. C. Porter. 



All the species of Carex contained in this list are represented in 

 the herbarium of Lafayette College by specimens from all the coun- 

 ties named, Avith the single exception of C. Torreyi. It will be 

 observed, that, contrary to the common usage, the county is put first, 

 the particular station next, and then, the name of the collector, in 

 italics. When the latter is wanting, it indicates that the author 

 himself is the collector. 



The order of arrangement and most of the changes in nomencla- 

 ture are taken from the Synopsis of North American Cnrices, by L. 

 H. Bailey, Jr., published in the Proceedings of the American Acad- 

 emy of Arts and Sciences, 1886.
