Dr. M. A. Howe, Curator, has cared for the collections 

 of algae and hepatics. He continued his studies and 

 descriptive work in the North American algae, and col- 

 lected algae and other cryptogams in Jamaica and Cuba 

 during the early part of the year and in Panama during the 

 latter part. Dr. Howe continued to serve as editor of the 

 Torrey Botanical Club, having special charge of its Bulle- 

 tin and Memoirs. He also assisted in the nature study 

 course given at the Garden in cooperation with the public 

 schools of the city. 



Dr. W. A. Murrill, Assistant Director, and Mr. F. J. 

 Seaver, Director of the Laboratories, conserved and de- 

 veloped the collections of fungi. (For particulars see the 

 reports of the Assistant Director and the Director of the 

 Laboratories.) 



Mrs. N. L. Britton continued to lend her voluntary aid 

 in the developing of the moss collection. Besides vigor- 

 ously pushing forward the incorporation of the Mitten moss 

 herbarium in the collections, she has had the duplicates 

 of the Mitten herbarium prepared for sending to other 

 institutions as exchanges, and has supervised the prepa- 

 ration of a card catalogue of all the North American mosses 

 enumerated in the "Pflanzenfamilien." Mrs. Britton has 

 named collections of mosses made by herself in both Cuba 

 and Jamaica, and has given critical study to several genera 

 for a forthcoming part of "North American Flora." 



Mr. R. S. Williams, Assistant Curator, has had charge of 

 the collections of lichens. He has cooperated with Mrs. 

 Britton in the development of the moss collection and 

 in the naming of recently acquired specimens and has also 

 done a considerable amount of work on Mexican and Cen- 

 tral American mosses; and the genera Camfylophus, Cam- 

 pylopodium, Dicranella, Dicranum, Oncophorus and Leu- 

 coloma have been monographed, for publication in "North 

 American Flora." Mr. Williams also assisted in the 

 nature study courses at the Garden in cooperation with 

 public schools of the city.
