Description
Euphorbia grandicornis is a shrub with succulent, spiny stems that reaches a size of 0.5–2 m in height. Small leaves are formed between the spines but later drop off; the stems do the bulk of the photosynthesis. It is much branched from the base, with thorns, the branches 3-angled, erect or ascending, very deeply constricted in segments, subsagittate-ovate or reniform-sagittate, 5–13 cm long and 5 – 15 cm in diameter. The fruit is showy and pops open when ripe. ==Subspecies==
