Thank you Ken & Ursula.
Ursula, the Uncarina may be a decaryi after talking to my expert friend yesterday. We are trying to figure it all out! We took cuttings and photos from each tree and he's showing them to yet another expert tomorrow. Such a mystery. My friend and I are also trying to root some cuttings from the Uncarinas...."they" say it cannot be done...but we are going to prove them wrong! (Or kill our cuttings trying!)
