" Mrs. M. P.," Lynn, Mass., sends a very interesting specimen and says: "I enclose a bud from a Douglas rose growing in my greenhouse. Can you explain why it should grow in such a singular manner? Please answer in the Monthly. The April number is full of good things".

[All the parts of a flower are merely leaves changed to the various floral organs. The rose proves this better than many others, for rose leaves often turn partially to petals, or the petals go back to leaves. In the present case the calyx segments have become perfect leaves, not like the ordinary rose leaves, but lobed like the striped bark maple leaf. We never saw a case just like this.-Ed. G. M].
