observations here recorded 



were made at Rehoboth Beach, Delaware, as a small addition to 

 the increasing collection of data from the Atlantic seacoast. In 

 sequence and nomenclature an attempt is made to harmonize 

 these results with those obtained by Mr. Kearney^ and Dr. 

 Harshberger^, on Ocracoke island and the New Jersey coast, 

 respectively. The Britton and Brown nomenclature is used 

 throughout, with the synonyms from Gray's Manual, where such 

 occur, in parentheses. The list of plants does not claim to be 

 complete, as the work was done during the summer months, and 

 therefore the flowers of many species had disappeared, while 

 other forms had not yet flowered, making identification difficult 

 and at times impossible. Many forms were doubtless over- 

 looked in the one or two visits which limited the opportunities 

 for study In some parts of the field. The algae and fungi were 

 not studied, while the lichens and mosses received the most 

 superficial attention. 



I. GEOGRAPHY. 



The region studied extends from Cape Henlopen to a little 

 over a mile south of Rehoboth, including a tract of land about 

 six and a half miles long, by one-half to one mile in width, lying 

 on the mainland, instead of on a fringing chain of islands, which 

 is the usual condition along the Atlantic coast. The trend of the
