Ahh, so you haven't moved yet?
I have undulatus - I found this corm rolling around in my 2ft guppy tank that had a couple of weasely roots on it, so I stuffed it in the substrate and bingo - undulatus!
I got it from an ex NZKA member a few years ago and thought it had gone into hibernation or whatever it is and then disappeared, he said it was crispus, but the end of the leaves are too round.
It has sprouted a long thingy without a leaf on it that is running across the top of my tank, so hopefully it may be a pup.
Will send the crypts next week.
