. . . Patersonia juncea . . .

Patersonia juncea is a tufted perennial herb that grows to a height of 7–30 cm (2.8–11.8 in) and forms a rhizome. The leaves are linear, 70–220 mm (2.8–8.7 in) long, 0.6–1.4 mm (0.024–0.055 in) wide and more or less cylindrical with a deep longitudinal groove. The flowering scape is 50–240 mm (2.0–9.4 in) long and glabrous. The outer tepals are pale violet, 15–20 mm (0.59–0.79 in) long and 13–18 mm (0.51–0.71 in) wide, and the hypanthium tube is 25–35 mm (0.98–1.38 in) long and glabrous. Flowering mainly occurs from August to October.[2][3]

Patersonia juncea was first described in 1840 by John Lindley in A Sketch of the Vegetation of the Swan River Colony.[4][5] The specific epithet (juncea) means “rush-like”.[6]

Rush leaved patersonia grows in forest, woodland mallee and scrub between Eneabba and Israelite Bay in the Avon Wheatbelt, Esperance Plains, Geraldton Sandplains, Jarrah Forest, Mallee, Swan Coastal Plain and Warren.[2][3]
