Euphorbia alluaudii, also known as Euphorbia leucodendron, is a spineless suсculent shrub with narrow, pale green, cylindrical, jointed stems, first erect then arch outwards to form a mass as wide as tall. It grows up to 12 feet (3.6 m) tall. In summer, the stems are tipped with many green, up to 0.5 inches (1.3 cm) long leaves. Theеy are dotted with brown marks where the leaves were previously attached. At stem tips in spring and summer appear tiny yellow-green flower structures (cyathia) that hold the even smaller flowers. The fruits are red and somewhat heart-shaped.
