  • Question

    These are two plants growing near each other at the edge of a clearing in Lincoln, Massachusetts. The key to Rubus requires flowers. Can anything be said about them without pictures of flowers?

    Answer

    Dear jfc, these blackberries can be identified now, but not from the images provided. We need to know about the primocanes (the first-year vegetative stems, their orientation and their prickles), the leaf undersurfaces (for pubescence), and whether or not stipitate glands are present in the inflorescence. You don't absolutely have to have flowers to identify this blackberry, but more information is needed. Best wishes.
