report observations on the characteristics and relative abundance 

 of the particular form or forms that they find at various stations. 

 The writer will be pleased to receive fresh leaves and flowers 

 for comparison with the species and races now growing at the 

 New York Botanical Garden. If branches with flower buds 

 are cut a day before the flowers are to open, slightly dampened 

 with water, and immediately wrapped in paper and enclosed in a 

 pasteboard box, they will keep in rather good condition for 

 several days. Herbarium specimens may be made and while 

 not revealing much regarding flower colors these are excellent 

 for a study of leaf and pod characters. 



It is also planned to extend the cultures at the New York 

 Botanical Garden to include as many as possible of the different 

 races or species found in nature. Plants can be transplanted at, 

 or soon after, the close of the flowering period; the stems can 

 be cut away, most of the dirt shaken from the roots, and the 

 plant wrapped in paper to prevent drying out and shipped as 

 soon as is convenient. A large majority of plants thus treated 

 have lived when transplanted to the experimental plots, if 

 possible, however, three plants of a particular form should be 

 sent to insure against possible death of some. 



The writer will fully appreciate any cooperation which will 

 facilitate the study of these interesting and variable species.
