Stuck on the last three. I wonder if I have a mistake. Here is what I have. Pointers gratefully received.
44a. Mongrel receives a name as badly bred (6) -U-F-T. I guess the mongrel bit means cur at the start, but the rest?
51a A gardener finally put up with volunteers, in these? (8)-R-O-E-A. It looks like a latin plant name?
Thanks in advance.
