Andersonia pinaster

Andersonia pinaster is a slender, erect, pine-like shrub, that typically grows up to 0.5–1 m (1 ft 8 in – 3 ft 3 in) high. The leaves are twisted, narrowly egg-shaped to almost linear, and 10–20 mm (0.39–0.79 in) long. The flowers are arranged on the ends of branches, hidden by leaf-like appendages until the flowers open, the sepals narrowly egg-shaped, 9.5–14 mm (0.37–0.55 in) long and green. The petals are bright blue and form a narrowly urn-shaped tube 9.5–14 mm (0.37–0.55 in) long with widely spreading lobes 5.8–8 mm (0.23–0.31 in) long with soft hairs that form a tuft at the end of the lobe. The stamens are 6.2–10 mm (0.24–0.39 in) long, the anthers white, 1.3–2.0 mm (0.051–0.079 in) long. Flowering occurs from July to September.^[2][3]

Andersonia pinaster was first formally described in 2007 by Kristina L. Lemson in the journal Nuytsia from specimens collected near Betty's Beach by Greg Keighery in 1986.^[2][4] The specific epithet (pinaster) refers to the habit of mature plants, which resemble a small pine tree.^[2]

This species of Andersonia grows in low heath in Two Peoples Bay Nature Reserve in the Jarrah Forest bioregion of southern Western Australia.^[3]

Andersonia pinaster is listed as "Threatened Flora (Declared Rare Flora — Extant)" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.^[3][5]
