Can anyone ID my Pinguicula?

[Rowangreen]

Guess who just happened to be in the region of Columbia Road Flower Market in London... thought I was safe as the only orchids there today were boring noid phals.

But the last stall had a selection of flytraps, and one solitary ping... So I got 2 for the fiver I just happened to have on me!

Then I remembered I'd been thinking of getting some Mexican pings and I'd forgotten to ask what culture it needed...

Anyone identify this so I can work out what it needs? I'm thinking Tina or moranensis, but don't think that's quite right so anyone know it?

Also will they both be OK with a bit of possibly quite hard London water until I can get hold of some distilled?

Should I try and remove dead traps and leaves?

Thanks!
