Description
editAndersonia geniculata is a low, spreading or cushion-like shrub, that typically grows up to 5–20 cm (2.0–7.9 in) high and 20 cm (7.9 in) wide. The leaves are twisted, linear or very narrowly egg-shaped, and 7–11 mm (0.28–0.43 in) long. The flowers are arranged in clusters of five to ten in leaf axils, with egg-shaped, leaf-like bracteoles 6–8 mm (0.24–0.31 in) long. The sepals are narrowly egg-shaped, 8–10.5 mm (0.31–0.41 in) long and creamy-white. The petals are white and form an oval to cup-shaped tube 7.5–10.5 mm (0.30–0.41 in) long with linear lobes 4.6–5.8 mm (0.18–0.23 in) long. The stamens are 5.5–8.5 mm (0.22–0.33 in) long, the anthers yellow and oblong, 1.6–3 mm (0.063–0.118 in) long. Flowering occurs from late August to early November.[2][3]
Taxonomy
editAndersonia geniculata was first formally described in 2007 by Kristina L. Lemson in the journal Nuytsia from specimens collected 21 km (13 mi) north of Walpole in 1994.[2][4] The specific epithet (geniculata) means 'with bended knee', and refers to the stamen filaments.[2]
Distribution and habitat
editThis species of Andersonia grows in low sedgeland on the edges of swamps and in open areas in forest, between Manjimup and Walpole, in the Jarrah Forest and Warren bioregions of south-western Western Australia.[2]
Conservation status
editAndersonia geniculata is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.[3]
