(AKA mini split-leaf Philodendron)

I've been looking for this one for almost a year now. I've googled it, checked online vendors that I know of, and have a saved search on eBay, all of which turned up nothing. I find this a little odd since this is such a nice looking plant that supposedly grows like a weed in cultivation.

If anyone knows where I could find one, or has a cutting they could spare, I'd greatly appreciate it. I'm building a greenhouse this summer and would love to see this plant growing in it.
