Exchange opuntioids

I have a smaller surplus of cold hardy Maihueniopsis for exchange. They have proven hardy for me to at least minus 19C for weeks of being frozen. Im sure they take it colder down south where there is more winter sun.
Im looking for cuttings or seeds of named locations or cultivars of smaller US opuntioids like polyacantha, aurea, debrechzyi, fragilis etc.

Seeking Pseudotrillium rivale forma reticulatum

Hi,
I know this is a major long shot but I'd love to get my hot little hands on a piece of rhizome or even seed of a heavily silver veined form of Pseudotrillium (Trillium) rivale. I know someone who has managed to tissue culture trilliums so you can see where I'm going with this..... If you've got this baby and are overseas seed is no problem-I have a seed import permit.

I have (if it hasn't drowned) Pseudotrillium rivale "Purple Heart" or Trillium kurabayashii seed (not ripe yet) to trade. I can also most likely scare up some Trillium ovatum seed later this summer.

Crepis incana

Does anyone know a supplier of Crepis incana plants or seed in the US? I've had an enquiry from someone in Maine.
Although I know several people who grow the plant in the UK, the plants rarely make viable seed here. I'm not sure if that is due to lack of summer heat or the need for a second plant. I'll pass on any contacts to the person who contacted me.

Here's a picture of mine at its best last year (picture taken late July 2011)
