I hav been recently told that this plant, which I have had since 2006/7, perhaps earlier (I actually think I acquired it in 2005 based on my earliest photos of it from way back in the wayback) is one of the most pure unadulterated forms to be currently in existence. Plants in older collections like mine are sometimes that way...over the intervening years they get hybridized, or new forms with morphological differences can emerge out of tissue culture or whatnot. Lately there has been some renewed interest in this plant...they have discovered that plants growing in Panama can have distinct morphological differences just based on which side of a hillside they are growing on, in the same locale! Isn;t that wild?
