Looking to trade for Hemianthus callitrichoides (see list!)

Hi there,

I'm very interested in obtaining a portion of this plant for a mini plant tank I'm setting up. I'm willing to trade what I can for it. I have available:
Crypt. retrospiralis
Crypt Balansae
Aponogeton boivinianus
Hemianthus Micranthemoids
Glossostigma
Bolbitis heudelotii
Riccia
dwarf hairgrass
Crinum calamistratum
or a couple attractive but unidentified natives (grass-like leaves for the midground)
I am also very interested in any aquatic ferns mosses or liverworts that anyone would want to trade for any of the above.

Thanks!
