I have a large air-layered N. maxima 'Broad Peristome' x 'Celebes Striped' to trade:
The most striking feature of this clone is that the peristomes become a deep reddish brown to nearly black when grown in strong light. The plant is 12" tall to the base of the highest leaf. The 6th leaf is opening now and they're 6"+ (not including stem or tendril). It's in a 4" pot and has been off the parent plant for a couple months.
I'm interested in other highland - intermediate species Neps. N. ephippiata is probably at the top of my wish list, but I'll consider any that aren't N. fusca, maxima, sanguinea, or ventricosa. I might trade for non-Neps and non-CPs too.
