Conostylis dielsii is a tufted
Description
Conostylis dielsii is a tufted perennial, grass-like plant or herb that forms short rhizomes and typically grows to 13–33 cm (5.1–13.0 in) high. The leaves are round in cross-section, 7–330 mm (0.28–12.99 in) long and 0.5–1.8 mm (0.020–0.071 in) wide and
Taxonomy and naming
Conostylis dielsii was first formally described in 1903 by
In 1987, Stephen Hopper described two subspecies of C. dielsii in the Flora of Australia, and the names are accepted by the Australian Plant Census:
- Conostylis dielsii W.Fitzg. subsp. dielsii[7] has leaves 70–155 mm (2.8–6.1 in) long and 0.8–1.8 mm (0.031–0.071 in) wide, the flowering stalk 20–100 mm (0.79–3.94 in) long.[8]
- Conostylis dielsii subsp. teres Hopper[9] has leaves 130–330 mm (5.1–13.0 in) long and less than 1.0 mm (0.039 in) wide, the flowering stalk 10–145 mm (0.39–5.71 in) long.[10]
Distribution and habitat
This species of conostylis grows in low open woodland in sand and gravel between Mingenew, Walkaway and the Arrowsmith River in the Avon Wheatbelt and Geraldton Sandplains bioregions of south-western Western Australia.[2][3] Subspecies teres grows in heath and low open woodland and is restricted to uplands inland from Walkaway in the Geraldton Sandplains bioregion.[10][11]
Conservation status
Conostylis dielsii is listed as "not threatened"[3] but subsp. teres is listed as Threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions,[11] meaning that it is in danger of extinction.[12]
