The announced scientific programme consisted of a "Sym- 

 posium of the Flora of Bermuda," introduced by Dr. N. L. 

 Britton. Others taking part in the symposium were Dr. M. A. 

 Howe, Miss Margaret Slosson, Dr. B. O. Dodge, Dr. W. A. 

 Murrill, Mrs. N. L. Britton, Mr, Stewardson Brown, and 

 Professor Charles L. Bristol. 



Dr. N. L. Britton presented a paper on our present knowledge 

 of the Bermuda flora, which will be published in the Journal 

 of the New York Botanical Garden. 



The following abstracts of the other papers presented were 

 prepared by the speakers: 



Dr. Marshall A. Howe spoke briefly of some of the more 

 striking features of the rich and varied marine flora of Bermuda. 

 He remarked that there were probably as many species of plants 

 inhabiting the sea in that region as were found on the dry land. 

 The marine algae of Bermuda are closely related to those of 

 southern Florida and the West Indies, though several species 

 have been described that appear to be endemic to Bermuda. 

 Specimens were exhibited, illustrating particularly the order 

 Siphonales, such as the genera Caulerpa, Halimeda, Udotea, 

 and Penicillus, all of which are well represented in Bermuda. 



Miss Slosson stated that the fern flora of Bermuda, as repre- 

 sented in the herbarium of the New York Botanical Garden, 

 consists of 1.9 species included in 13 genera. One of the genera 

 belongs to the family Osmundaceae and the remaining to the 

 family Polypodiaceae. Two families of fern-allies, Salviniaceae 

 and Psilotaceae, are also represented, each by a single species. 

 The list of species and genera is as follows:

Osmunda 0. regalis, 0. cinnamomea.
