I'm doubting if there's any crispus in it even if it's a hybrid. I would
expect longer submerged leaves than just a couple of inches if there was
some crispus. I do have a few cripus (probably hybrids, picked them up at
an auction several years back) in another tank but they've only produced 1
seed in several years otherwise I'd have used them for this new tank.

Crispus is having a hard time. I've been told by many people it's extinct
in the wild. Whether this is true I don't know but it has been for me
imposible to find. You have to "settle" for lungiplumulosus, capronii
or the live bearing stachysporousd/undulatus. long. looks like
crispus, capronii has radically undulated leaves that look almost
corkscrew.

I've pretty much prepared to get hybrids whenever anyone sells "crispus",
but this purchase was so far off from expected that I'm a wee bit miffed.
I should have known better than to trust that shop with plant IDs though.
It's a large LFS, long established, but definately more into fish and
supplies than plants.

Anyways, I was able to get my digital camera and new machine to talk to
each other successfully today, so here's a few photos:
