btw Paul, I found another ericarum on George Sangiouloglou's website and it says Ex. World Record size. It is 208mm and being sold for $800. (I had no idea it is worth that much.hahaha) I was trying to email him about my specimen but can't get it through. <img src="images/smiley/frown.gif" alt="" border="0" /> Just wanted to tell him about my 214mm specimen. I almost gave it to a friend for $15. If my ericarum is the world record size, i don't what do with it. It will stay in my cabinet for awhile longer probably.   <img src="images/smiley/lol.gif" alt="" border="0" />
