Let Matt know about the roots on the walkeriana. He has been very good about replacements for me, especially if I tell him right away. Also get the scoop on the bean dendrobium's name! I want one of those! (Uh-oh. I seem to be very attracted to dendrobiums but I kill most! I would love to get a moniliforme (used to have 3). What medium do you use? watering?)
