THE FLORA OF COLD SPRING HARBOR AND 

 BOTANICAL RESEARCH 



Opportunities for the systematic botanist are indicated 

 at least in the paucity of records for certain plant groups 

 in the accompanying list, especially the ciyptogams. The 

 records to date include the following main divisions of the 

 plant kingdom, exclusive of the Bacteria, and to this list 

 may be added the records of Jelliffe • ('99-'04) Burnham and 

 Latham ('14-'24) Fish ('25), Bigelow ('22).

Protozoologists have remarked upon the unusual rich- 

 ness of the Flagellate flora of the Cold Spring region, but 

 this has received little attention so far. The American forms 

 should be more comprehensively studied, following the lead 

 of Walton ('15). Additional records for the Dinoflagellates,
