I think if I could get my hands on some U. nelumbifolia, I'd keep it for myself LONG before I'd put it at the mercy of the University's greenhouse!
And I like the idea of the pygmy drosera. I put some D. nitidula x pulchella long ago, but it was lost when they stopped caring for it. I still have my plants, and they just produced gemmae. I'll have to see if there are any in there that aren't too far developed and put them around there.
