The leaves are narrowly lance-shaped to elliptic, 7–11 mm (0.28–0.43 in) long and 1.1–1.3 mm (0.043–0.051 in) wide with a small, short point on the tip. The flowers are arranged in clusters in leaf axils near the ends of branches on a peduncle covered with bracts. The petals form a cylindrical tube with the stamens and style protruding above the petal lobes.[2][3]
