Stenanthemum yorkense is a species of flowering plant in the family Rhamnaceae and is endemic to an area near York in the southwest of Western Australia. It is a low, spreading shrub with egg-shaped leaves, the narrower end towards the base, and densely crowded, head-like clusters of white, tube-shaped flowers with a yellow centre.
Stenanthemum yorkense is a spreading shrub that typically grows to a height of 10–15 cm (3.9–5.9 in), its young stems densely covered with whitish hairs. Its leaves are grass-like at first, later egg-shaped to broadly egg-shaped, the narrower end towards the base, 8–17 mm (0.31–0.67 in) long and 4–8 mm (0.16–0.31 in) wide on a densely hairy petiole 3–4 mm (0.12–0.16 in) long. There are stipules 5–6 mm (0.20–0.24 in) long and fused for about half their length at the base of the leaf. The flowers are white with a yellow centre, and borne in clusters up to 14 mm (0.55 in) wide. The floral tube is densely hairy, 3.5–4.5 mm (0.14–0.18 in) long, the sepals densely covered with curly hairs and about 1.3 mm (0.051 in) long. The petals are about 0.6 mm (0.024 in) long, and the fruit is spherical and about 2 mm (0.079 in) long and densely hairy.[2][3]
