Can you add a description to this picture? I'm currently cleaning up my Bursera collection and this reminds me of Bursera. It could be just about any bipinnate tree/shrub from the picture. I will assume this was purchased from a succulent nursery and as such could then possibly be Burseraceae. Rub a leaflet between your fingers. Does this produce a nice medicinal smell? Are the leaves glabrous or are any hairs on the underside? Is the trunk slightly swollen? Does the bark show any signs of peeling. If so, what color is underneath and what color is the peeling bark. For any possitive I.D. you will really need to see flowers and seeds. If any of the above applies this could be B. stenophylla (minus the peeling bark).
