116 BROOKLYN BOTANIC GARDEN MEMOIRS 



listed by Dr. Millspaugh in his "Flora of the Island of St. Croix," as 

 determined by J. B. Ellis and F. D. Kelsey. 18 



Thirty-one species brought by various collectors to Copenhagen, 

 determined by E. Rostrop, are recorded by BjzSrgesen and Paulsen in 

 their "Vegetation des Antilles Danoises." 



Seven species, collected on St. Thomas during the voyage of the 

 "Challenger," are listed by M. J. Berkeley in Journal of the Linnean 

 Society 14: 352. 



These records duplicate each other considerably, indicating a 

 known fungus flora of somewhat over fifty species only. Inasmuch 

 as there must be several hundred species on the islands, a list of 

 fungi is deferred for further mycological field work. 



Algae 19 



"The Marine Algae of the Danish West Indies" is the title of a 

 work, now appearing in parts, in which Dr. F. BpTgesen, of Copen- 

 hagen, is carefully describing and adequately illustrating the seaweeds 

 of these islands. His adoption of the English language in this work 

 makes it immediately serviceable to American students. Volume 1, 

 including the Chlorophyceae (Green Algae) and Phaeophyceae (Brown 

 Algae), was published in 1913 and 1914, and, at the date of writing, 

 the first 240 pages of Volume 2, dealing with the Rhodophyceae (Red 

 Algae) have appeared. Other papers of importance, dealing with the 

 algae of the Danish West Indies, are the following:
