Norske bjørnebær 6. Sørlandsbjørnebær Rubus ”firmus”
(2021) In Blyttia: norsk botanisk forenings tidsskrift 79(1). p.39-45- Abstract
Rubus "firmus" is a very rare plant in Norway; it is only known from a 500 m long coastal strip nearthe sea- shore in Grimstad, Aust-Agder fylke. The identity of the name R. firmus is obscure, and it is not known whether the original plant is a species or a hybrid; we do not accept this name as correct for the Norwegian plant. The Norwegian plants are not very homogeneous and have the chromosome number 2n = 42. We believe they are the primary hybrid between Rubus caeslus and probably R. norvegicus. This hybrid is abundantly fertile and produces the earliest mature fruits of any Norwegian blackberries.
