Pimelea stricta, commonly known as gaunt rice-flower,[2] is a species of flowering plant in the family Thymelaeaceae and is endemic to south-eastern continental Australia. It is an erect shrub with narrowly elliptic or linear leaves, and compact heads of densely hairy, creamy-white to yellow flowers surrounded by 4 egg-shaped involucral bracts.
Description
Pimelea stricta is an erect shrub that typically grows to a height of 0.5–1.5 m (1 ft 8 in – 4 ft 11 in) and has glabrous stems. The leaves are arranged in opposite pairs and are narrowly elliptic or linear, 5–35 mm (0.20–1.38 in) long and 1.0–4.5 mm (0.039–0.177 in) wide on a short petiole. The flowers are bisexual and borne in compact clusters of many hairy, creamy-white to yellow flowers, surrounded by 4 egg-shaped involucral bracts 5–13 mm (0.20–0.51 in) and 3–9 mm (0.12–0.35 in) wide. The bracts are medium green, sometimes with a yellowish or reddish tinge. The floral tube is 7–12 mm (0.28–0.47 in) long, and the sepals are 2–4 mm (0.079–0.157 in) long. Flowering occurs in most months with a peak between August and November.[2][3][4][5]
Taxonomy
Pimelea stricta was first formally described in 1854 by Carl Meissner in the journal Linnaea from specimens collected in the Mount Lofty Ranges.[6] The specific epithet, (stricta) means "straight" or "upright".[7]
Distribution and habitat
Gaunt rice-flower mainly grows in open woodland, in mallee or on hills in sandy soils, and is found from north-eastern New South Wales through Victoria to the Eyre Peninsula and Flinders Ranges in south-eastern South Australia.[2][3][4][5]
