Thank you Lynn but cultivars from other parts of the world, where to place them and how or just dump them in the Genus and let people worry what on earth is going on? Ziziphus zizyphus leaves are about the size of a big toe nail while Zizphus nummularia leaves are my small finger nail size, maybe your index finger. The one above, the leaves go up to five inches. From now on I am going to carry a steel ruler and hooks, never thought about this aspect.
