Euphorbia baionensis

It is a succulent plant, which was found on the Baio mountain in Kenya, hence its name. From the base new cylindrical, green-gary stems emerge, which are completely covered with thick gray thorns. These thorns are of a gray color, and as they grow they tend to become darker, of an almost black color. In spring, its beautiful yellow flowers bloom; there are many of them, and they are arranged along the stems.
