Cooperative Plantations 



Because the area still available For planting on our grounds at 

 Hamden is limited, we have continued our plan of giving young 

 seedlings for planting to interested and reliable parties. A mere 

 list of these would cover several pages. In all, we have given 

 away more than 1,500 seedlings during the past year, mostly to 

 landowners in Connecticut, but to some in New York State, New 

 Jersey, and elsewhere. A large proportion of these seedlings had 

 been grown by us from Japanese and Chinese windfalls of 1939. 



During the year we have received assistance in many ways from 

 the Division of Forest Pathology, U.S. I). A., whose cordial co- 

 operation we have enjoyed since we began this work. We are glad 

 to have the opportunity to acknowledge this assistance here.

Flower Structure and the Classification of Dicotyledons 



By Alfred Gundersen 



The past year I have given as much time as possible to the study 

 of flower structures in our increasing collections. Drawings of 

 buds and flowers were continued by Miss Maud II. Purely, staff 

 artist; another color study, Sarraceuia flava, was completed, mak- 

 ing eleven in all. I have given attention especially to plants with 

 basal placentation. also to the families Aristolochiaceae and Stachy- 

 uraceae, and to a comparison ol systems of classification.
