I talked about taking a Cattleya walkeriana apart and here is the result. One pot (lower right) has the visible lead and another (lower left) has the lead I suspected from the condition of one of the pseudobulbs. The picture to the right is a close-up of that lead.
I don't know for sure that any of them will grow but I am going to be optimistic and catalog them all. Then when they do take off I will have some kind of notes. I am always wishing for better notes.
