Seringia undulata

Seringia undulata is a suckering, upright shrub that typically grows to a height of 0.4–1.5 m (1 ft 4 in – 4 ft 11 in), about 0.5–2 m (1 ft 8 in – 6 ft 7 in) wide, and has rust-coloured, hairy stems. The leaves are oblong, 2–7 mm (0.079–0.276 in) long and 2–3 mm (0.079–0.118 in) wide on a petiole up to 3 mm (0.12 in) long with tiny stipules at the base. The edges of the leaves are curved downwards and wavy, the upper surface more or less glabrous and the lower surface densely covered with rust-coloured and white, star-shaped hairs. The flowers are arranged in a cyme about 30 mm (1.2 in) long with 6 to 8 flowers on a peduncle 4–7 mm (0.16–0.28 in) long, each flower on a pedicel 5–10 mm (0.20–0.39 in) long. The flowers are 20 mm (0.79 in) wide and purple with petal-like sepals joined at the base to form a tube with lobes two-thirds the length of the tube. Petals are absent and the stamens have yellow filaments, and dark coloured anthers. Flowering occurs from May to October.

This species of seringia is only known from the Bremer Range area where it grows on roadsides or in sandy or loamy soils over ironstone in the Coolgardie bioregion of inland Western Australia.
