Moss and Hepatic Herbarium and the Underwood Hepatic 

 Herbarium. 



Six standard herbarium cases, several wall cases, and 

 a book-case were added to the herbarium equipment. 



The rapid and uneven accumulation of herbarium ma- 

 terial necessitated two general movings of nearly all the 

 herbarium specimens and a temporary arrangement of 



Assistance and Investigations 



Dr. Arthur Hollick, Curator, looked after the develop- 

 ment of the collection of fossil plants, and, in connection 

 with the work of determining and labeling the specimens, 

 he prepared and printed several papers on paleobotanical 

 subjects. He continued his studies on the living and ex- 

 tinct flora of Staten Island with special reference to the 

 Cretaceous period, making a complete study of all the 

 local material from Staten Island, Long Island, Block 

 Island, and Martha's Vineyard not previously described. 

 He edited the parts of the Bulletin of the Garden pub- 

 lished during the year, delivered three lectures on the 

 Garden lecture course, and represented the Garden at the 

 Buffalo meeting of the American Association of Museums. 

 Mr. Edwin W. Humphreys continued his voluntary assist- 

 ance as heretofore, and, in addition, prepared a monograph 

 of the genus Buthotrephis. 



Dr. Marshall A. Howe, Curator, cared for the collections 

 of algae and hepaticae. He spent the first part of January 

 in the Canal Zone, Panama, in continuation of the explora- 

 tions mentioned in our last report, giving special attention 

 to the collection of marine algae, and of the lower crypto- 

 grams among the land plants. The herbarium work under 

 his direction has resulted during the year in adding about 

 4,200 mounted sheets, about equally divided between algae 

 and hepatics, to the collections. Dr. Howe also selected 

 over 300 photographic negatives of botanical interest 

 from which enlarged prints for the walls of the Systematic
