Dr. Britton exhibited the fourth fascicle of Messrs. Collins, 
Holden & Setchell’s “ Phycotheca Boreali-Americana,” and spoke 
of the value of this work. 
Dr. Britton also called attention to a sedge, Remuiria maritima, 
recently found at Lake Worth, Florida, but having a wide distri- 
bution in tropical maritime regions. 
The announced paper of the evening was then read by Miss 
Alexandrina Taylor, entitled « A Comparative Study of the Su- 
perficial Periderm in a number of species of Salix.” This was ac- 
companied by diagrams illustrating the work. In the superficial 
periderm of these genus there are many variations from that 
selected as the type by Sanio, and the object of this study was to 
see if, by examining a greater number of species, one might not 
be found which might more justly be called the type of the genus. 
The paper was commented upon by Dr. Britton and Dr. Allen.
