Hey Mark, I don't know if I have anything you are interested in, but, if so, I'd love to make some swaps with you.
The thing I'd probably like the most is 28. Phyllostachys nigra IF you could get one with a pretty well developed root system. I got one from you before but it never sprouted any roots. I still have the spot that I planted it in reserved in case I ever got a chance to get another one.
The other things that interest me if you have them available and want to trade are...
8. Neviusia alabamensis
17. Calycanthus x venus
15. Buddleia lindleyana
