I received these Biarums from the late Marcus Harvey. Unfortunately he had not identified the species of either.
The first biarum was grown from seed collected in North East Turkey and the tuber looks like a biarum (Biarum 'NE Turkey').
I have mislaid the details of seed collection for the second Biarum (Biarum 'Pink & White').The tuber of this one looks more like an arum tuber. The small (3.5cm x 8.5cm) flower has an unusual spadix.
Any leads as to the species of either would be much appreciated. ...Regards Ray.
