Rubus allegheniensis Porter
Annotated by Doug Goldman, 2013.

British Columbia: Metro Vancouver, Burnaby, old Kenneth Gordon School, soon to be turned into parkland, 7855 Meadow Avenue. Elev. 6 m
49.197778° N, 122.971944° W,
Thick overgrown lawn in peaty substrate, 5 m from southwest side of fence. Single 1 m high mounded patch 3 x 4 m; fruit mostly sterile, but a very few with 1-3(4) drupelets per berry; fruticanes hidden in mass of primocanes; minute malformed glands present on the new leafy shoot tips and inflorescence; seems intermediate between Rubus armeniacus and allegheniensis. “Myself and one of the other FNA Rubus authors took a look at it separately and immediately we both recognized it as allegheniensis. Everything looks right for it to be that species. The small stipitate glands and slender stems suggest that the origin of that plant is from the southern Appalachians. This is exactly how this species looks in NC, SC, GA, TN, & vicinity.” - Doug Goldman, Nov 20, 2013.
