Thats a beautiful plant. I've been recently looking for one to buy but they seem to be very rare. I thought about trying to grow one from seed from ebay. I assume they take a very long time to be as awesome as yours. How old is your plant? Did you grow it from seed?

WOW ! MUST HAVE ONE ...haha ! Very nice indeed ! Kind of looks like a turtle shell !

I got this in a trade a couple years ago. Obviously a habitat plant that has been weather beaten.

The common name for this is tortoise plant, but that also includes elephantipes

Cool plant kieth

I found this old tread while I was researching for dioscorea macrostacha, here is a picture of one of this plants at 2013 intercity show in Arcadia California.
