Euphorbia greenwayi

A small perennial succulent plant, which is clustered at the base. Its triangular section stems have brownish-red needle-like thorns along the ribs. The plant is characterized by the contrast of its green and reddish colors, with lighter streaks in the center and darker shades on the prominent and pointed corners, which make it look like a rainbow. Like the other Euphorbias it blooms with small creamy yellow flowers.
