II. ADDITIONS TO THE LIST OF JAMAICA SEDGES 



In 1907 I contributed an enumeration of the sedges of Jamaica 

 to the Bulletin of the Jamaica Department of Agriculture (5 : 

 Supplement i). Further exploration of that island in the autumn 

 of 1907 and in the spring and autumn of 1908 has disclosed the 

 occurrence of some additional species and the habitat of others 

 which were recorded by me from the statements of other botanists.
