Balaustion multicaule

Balaustion multicaule is a shrub that typically grows to 15–30 cm (5.9–11.8 in) high and has many stems at its base. Its leaves are narrowly egg-shaped to very narrowly egg-shaped with the narrower end towards the base, or linear, about 3 mm (0.12 in) long and 0.5–0.7 mm (0.020–0.028 in) wide with one or two rows of oil glands each side of the midvein. The flowers are about 10–11 mm (0.39–0.43 in) in diameter, the flowers on a peduncle 3–5 mm (0.12–0.20 in) long. The floral tube is 1.7–2.3 mm (0.067–0.091 in) long and 3.0–4.5 mm (0.12–0.18 in) wide and green. The sepals are egg-shaped, about 1 mm (0.039 in) long, 1.6 mm (0.063 in) wide and red and the petals are pale pink, about 4 mm (0.16 in) long, with 18 to 20 stamens. Flowering occurs in October and November, and the fruit is a capsule 3.0–3.5 mm (0.12–0.14 in) long and 4–5 mm (0.16–0.20 in) in diameter.

This species of Balaustion grows in sandy soils in heath and is only known from the Sheoak Rock area, east of Hyden in the Mallee bioregion of south-western Western Australia.
