Pimelea filifolia is a species of flowering plant in the family Thymelaeaceae and is endemic to Arnhem Land in the Northern Territory of Australia. It is an erect herb with thread-like leaves and clusters of pale pink flowers.
Pimelea filifolia is an erect herb that typically grows to a height of 20–45 cm (7.9–17.7 in). The leaves are thread-like, 5–34 mm (0.20–1.34 in) long and 0.2–1 mm (0.0079–0.0394 in) wide. The flowers are arranged in clusters on a peduncle 40–100 mm (1.6–3.9 in) long surrounded by green and purplish, egg-shaped involucral bracts 3.5–7 mm (0.14–0.28 in) long and 2–5 mm (0.079–0.197 in) wide. The flowers are pale pink or purplish white, each on a pedicel up to 2.2 mm (0.087 in) long, the floral tube 4–10.5 mm (0.16–0.41 in) long and the sepals 1.1–1.6 mm (0.043–0.063 in) long. Flowering occurs between February and July. [2]
This species was first formally described in 1990 by Barbara Lynette Rye who gave it the name Thecanthes filifolia in the Flora of Australia from specimens collected by Clyde Dunlop. [2] [3] In 2016, Charles S.P. Foster and Murray J. Henwood changed the name to Pimelea filifolia in Australian Systematic Botany . [4] The specific epithet (filifolia) means "thread-leaved". [5]
Pimelea filifolia grows in sandy soil on sandstone pavement, usually near watercourses, from the far north to near Katherine, in Arnhem Land. [2] [6]
Pimelea filifolia is listed as "least" under the Northern Territory Territory Parks and Wildlife Conservation Act . [6]
