Description

edit

Acrotriche lancifolia is an erect, widely branched shrub that typically grows up to 1.5 m (4 ft 11 in) high and wide. The leaves are usually narrowly egg-shaped, sharply-pointed, 6–13 mm (0.24–0.51 in) long and 1.7–3.2 mm (0.067–0.126 in) wide on a petiole 1.0–1.6 mm (0.039–0.063 in) long. The flowers are arranged in groups of 4 to 9 in leaf axils with bracts and bracteoles 0.9–1.5 mm (0.035–0.059 in) long, the sepals 1.4–1.6 mm (0.055–0.063 in) long. The petals are green or greenish-yellow, and joined at the base forming a cylindrical tube 2.5–3.9 mm (0.098–0.154 in) and 1.1–1.5 mm (0.043–0.059 in) wide, with widely spreading lobes 1.0–1.3 mm (0.039–0.051 in) long and 0.7–0.9 mm (0.028–0.035 in) wide. Flowering mainly occurs from July to September, and the fruit is a spherical drupe 2.6–3.1 mm (0.10–0.12 in) long and 2.8–3.2 mm (0.11–0.13 in) wide.[2][3]

Taxonomy

edit

Acrotriche lancifolia was first formally described in 2007 by Michael Clyde Hislop in the journal Telopea from specimens collected in the Parker Range in 2003.[3][4] The specific epithet (lancifolia) means "lance-leaved".[5]

Distribution and habitat
