In a white cedar swamp there she observed the newly recognized 

 fern Dryoptcris simulata growing in great masses and abundantly 

 distinct. 



Mrs. Britton spoke also of certain instances of new habit as- 

 sumed by mosses on adopting a new habitat as in a Leptodon 

 usually on trees, latterly found in tufts on dry rocks ; and in case 

 of Porotric/ium Alleglianiaise, at Green Lake, Jamesville, New 

 York, an aquatic form surviving the desiccation of the rock sur- 

 faces, and now assuming the habit of a Climacium. 



Dr. Britton, whose summer was largely given to administra- 

 tive work, secured time for attendance upon the Association meet- 

 ings at Pittsburg, and for prosecution of his studies on the 

 Cyperaceae and th,e Crassulaceae at Kew. Nearly half of the 

 known species of North American Crassulaceae are now growing 

 in Washington or at the New York Botanical Garden, a necessary 

 preliminary to proper descriptive work with these plants. The 

 fleshy foliage and calyx require description from the life, not, as 

 often hitherto, from herbarium specimens. Many of the numerous 

 Mexican Crassulaceae are very local, and known only from one 

 or two localities. 



Discussion followed upon the effects of the prolonged wet 

 weather of the present season, Dr. Hazen remarking upon sedges 

 in Vermont which are usually stiff but this year were very long 

 and decumbent. Edward S. Burgess,

 20 persons present ; Dr. MacDougal in the chair. 



Professor D. S. Johnson, of the Johns Hopkins University, was 

 elected to active membership. 



Two resignations were accepted : Mrs. Francis S. Parsons, 

 Albany, and Miss Mary T. Pitman, Providence. 



The scientific program followed : The first paper presented 

 was by Miss F. A. Mulford, " Remarks on Gcrardia dccemloba, 

 Greene, with exhibition of specimens." The plant was found at 

 Hempstead, Long Island, September 5, 1902. This is the 

 second station for the species ; it was first found by Professor
