fungi sent in have been continued, including numerous 
specimens from Porto Rico collected by Mr. J. F. Steven- 
son. Several students have carried on investigations on 
fungi at the Garden during the year under his supervision 
who are looked to eventually for assistance on North 
American Flora. A number of papers have been published 
during the year. Work on fungous diseases and insect 
pests has been continued (see report of the Assistant 
Director) and one lecture delivered on the latter subject. 
Mr. Percy Wilson, Associate Curator, has devoted con- 
siderable time to determining and distributing West 
Indian plants. In the Bulletin of the New York Botanical 
Garden, issued in June, he published a paper on ‘‘The 
Vegetation of Vieques Island,” in which a comparison of its 
flora is made with that of the adjacent islands of Porto 
Rico, Culebra, St. Thomas, and St. Croix. He has also 
studied and determined for other institutions many speci- 
mens of tropical plants on which parasitic fungi occur. 
Mr. Wilson has continued his supervision of the lantern- 
slide and negative collections, and all photographic work. 
His duties as docent have been greatly increased as a 
larger number of classes for both public and private schools 
are taking advantage of the opportunity of viewing and 
studying the collections under special guidance. The 
Local Flora collection has been greatly increased by the 
addition of many specimens obtained on the various ex- 
cursions of the Torrey Botanical Club, of the Field Com- 
mittee of which Mr. Wilson has been chairman for several 
years. 
Dr. Francis W. Pennell, Associate Curator, active during 
the first half of the year, on leave during the second half, 
continued to have editorial supervision of the Journal for 
the earlier months of the year and continued his studies in 
the figwort family. He made an extensive trip for field 
work on that group, visiting South Carolina, Georgia, 
Florida, Alabama, Tennessee, and Virginia. Dr. Pennell 
published several papers on miscellaneous plants of the
