This is another 3-4 sided spiny, columnar Euphorbia, this one from Arabia. It has paired spines, some light green bands up and down the columns, and can form a caudex at its base. Not common in cultivation. Am happy to report after growing this a few years in the ground in southern California inland that it seems a relatively hardy plant (cold tolerant below 30F at least... but not sure yet how much colder... hope I don't find out to tell you the truth).
