Origin: Introduced from Europe
selected vouchers: WTU
Notes: FNA9: "No other species of Rubus within our region has leaflets so deeply lobed or dissected. The rare individual bearing relatively unlobed leaflets and perianth parts would appear most similar to R. vestitus, except that it lacks the apically flattened or cupulate glands of that species. Such unusual plants of R. laciniatus would be distinguished from the native blackberries by their cymose inflorescences, unlike the racemose or solitary inflorescences of the natives."
