My dear Professor Bessey:

How about Plums and Cherries? I have been rather hoping
that I should hear something from you about that Sandcherry and also
about the Nebraska Chokecherry which still perplexes me. I am get-
ting anxious about these things as I have to take up the genus next
winter and of course shall have to rely on material gathered this sum-
mer. I want very much to see specimens of the mature fruit and fo-
liage of the form of Prunus Americana which grows in your part of the
country. Can you find anyone who would be willing to send them to
me? I am inclined to think that there are two or three species con-
founded in what has usually been called Prunus Americana and I am try-
ing to clear up the doubts which exist in my mind about this tree.

I venture to ask for your co-operation.

Faithfully yours,
