Note
One of the most common species of succulent Euphorbia along the northern mountain ranges, variable in habit and robustness. Plants in shade, or on slopes influenced by the mist belt, tend to be taller, developing an obvious central stem with lax branching. Shrubs on drier south-facing slopes become more robust, with wider branches and a stronger spinescence. Spine-length is typically very variable on each branch, but at times of good growth spines can be of equal length, or become almost obsolete at times of little growth. From herbarium specimens the Somali populations appear to be conspecific with plants from the Gobelli Valley, south of Harar in Ethiopia, which are identified in Fl. Eth. Er. 2(2): 342 (1995) as E. nigrispina.
