Notes
When working out the Tropical African species of Euphorbia I had not investigated those of South Africa, but now that I have done so, I find that all the names above referred to this species certainly belong to one and the same plant. It therefore becomes necessary in accordance with the rule of priority to adopt the name E. inæquilatera, Sond., for this species instead of that of E. sanguinea, Hochst. and Steud., adopted in the Flora of Tropical Africa, because it is the first name for the plant that was published with a description. E. inæquilatera was published in 1850, and although the names E. parvifolia and E. setigera were published by Drège in 1843, they are mere names in a catalogue, unaccompanied by any description, and the name E. sanguinea was not published until 1862, when Boissier gave a description of it, as he then also did of E. parvifolia and E. setigera for the first time.
