Description
Patersonia macrantha is a tuft-forming herb with flat, linear to sword-shaped leaves 180–450 mm (7.1–17.7 in) long and 4–9 mm (0.16–0.35 in) wide. The flowering scape is 220–500 mm (8.7–19.7 in) long, smooth and softly-hairy near the tip, and the sheath enclosing the flowers is elliptic, 43–68 mm (1.7–2.7 in) long and pale brown. The outer tepals are pale violet, egg-shaped with the narrower end towards the base, or elliptic, 30–40 mm (1.2–1.6 in) long and 25–30 mm (0.98–1.18 in) wide. Flowering occurs from January to March.[2]
Taxonomy and naming
Patersonia macrantha was first described in 1846 by George Bentham in Flora Australiensis.[3] Bentham recorded that the type specimens were collected in the Darling Range by Alexander Collie.[4] However, the sheet bearing the type specimens in the Kew Herbarium was inscribed "Armstrong, Port Essington" in W.J. Hooker's handwriting, later crossed out by Bentham with a note "probably Darling Range, Collie (the loose scape was with the Darling Range occidentalis)".[5] The specific epithet (macrantha) means "large-flowered".[6]
Distribution and habitat
This patersonia is widespread in the northern part of the Northern Territory where it grows in forest and woodland.[2][7]

Patersonia macrantha is classified as "least concern" under the Northern Territory Government Northern Territory Government Territory Parks and Wildlife Conservation Act 1976.[7]
