Thanks. I'll need to have many more years of experience and dozens of clones before I can tell the difference. I stare at them again and I can't distinguish the features you described. I am poor at Nep hybrids ID so I think this deficiency has spilled over to Drosera.
I've already done that.
Another question...does D. petiolaris clump more readily? I see that in my plant but for paradoxa, I see only the rare one or two offshoots.
