The leaves are linear, 10–18 mm (0.39–0.71 in) long and 0.5–0.7 mm (0.020–0.028 in) wide and sessile or on a petiole up to 0.3 mm (0.012 in) long. The flowers are arranged singly near the ends of shoots on a thread-like peduncle 5.8–6.7 mm (0.23–0.26 in) long, with linear bracts 3.8–4.6 mm (0.15–0.18 in) long. The five sepals are joined at the base, the two outer sepal lobes linear to lance-shaped, about 4.5 mm (0.18 in) long and the inner lobes oblong to lance-shaped and 3.5–3.8 mm (0.14–0.15 in) long. The five petals are egg-shaped with the narrower end towards the base, yellow, 4.3–4.7 mm (0.17–0.19 in) long and there are twelve stamens arranged in five groups around the two carpels, each carpel with two ovules.
