Species spelling venefica invalid because it does not mean the right thing in Latin... should be venenifica (poison-making) as the Latin word for poison is venenum not venum. The abbreviated spelling would translate to "vein-making".

Closely related to other highly toxic West African succulent Euphorbias, including poissonii and unispina.

Per the International Plant Names Index regarding the spelling Euphorbia venenifica "Brown (in Fl. Trop. Africa 6(1): 562. 1911) cited the name as "Euphorbia venenifica Tremaux ex Kotschy" (an error)."
