Better-Gro recently put these out as bag babies in our local Lowe's. I picked up a few, and have an extra one to trade. It is blooming sized with one new lead growth. Pictures available of the one for trade available on request, (bloom pic below is just for reference, not the one up for trade.) If you've looked at eBay recently, all the walkeriana 'Carmela' are these bag babies and people are trying to charge a fortune for one, so don't pay it, you know how much these cost!

For trade I'm mostly looking for other Cattleya walkeriana forms, cultivars, etc, Cattleya nobiliors, or other cattleya species; intermedia, lawrenceana, violacea, or loddigesii. Seedlings or small divisions are fine, doesn't need to be BS.
