that forms mat-like stands some tall. For much of the year the stems are short, semi-prostrate and densely clad in leaves. At the flowering time in June and July, the stems lengthen and are erect, somewhat limp and often pinkish-brown with the leaves further apart. The leaves are alternate, fleshy and shortly cylindrical with a rounded tip. They are also sometimes tinged with red. The starry flowers form a three to six-flowered cyme. The calyx has five fleshy sepals fused at the base, the corolla consists of five regular bright yellow petals, there are ten stamens, a separate gynoecium and five pistils. The fruit consists of five united, many-seeded follicles. The leaves contain an acrid fluid that can cause skin rashes.
