The leaves are mostly arranged in opposite pairs along the branches and are linear to lance-shaped but mostly rolled so that they are 3–8 mm (0.1–0.3 in) long and less than 1 mm (0.04 in) wide on a short petiole. The leaves are covered with short, silky hairs. The flowers are pinkish-purple and arranged in rounded groups of three to twelve flowers on the ends of the branches. There are linear to lance-shaped bracts which are 4–7 mm (0.2–0.3 in) long and 1–2 mm (0.04–0.08 in) wide and paired bracteoles at the base of each flower. The floral cup is 3–4 mm (0.1–0.2 in) long and hairy. The sepals are triangular, about 1.5 mm (0.06 in) long and hairy. The petals are oblong to egg-shaped with the narrower end towards the base, about 1 mm (0.04 in) long and there are 50 to 64 stamens in several rows.
