Thanks for the advice, I will try that. I would think that any Anubius could hybridise with any other but only by cross pollination of flowers, the same as with the swords. I am down to one small colony of grindals at the moment (out of five) because I gave some away and I found that a good colony will out compete with the mites but when they get run down a bit the mites seem to win. I have very few plants at the moment as they got swallowed up by the shakes and the aftermath. I only have plants in a few terrariums ---no aquariums and the emersed setup is full of other stuff..
