Austrostipa mollis, also known as the soft speargrass or supple speargrass is a robust, erect tufted perennial speargrass in the Poaceae family. It is native to Australia, and found in Western Australia, South Australia, Victoria, ACT and Tasmania.[1]
It was first described as Stipa mollis by Robert Brown in 1810 from a specimen collected in Tasmania.[2] In 1996 was transferred to the genus Austrostipa.[3]
Description
A perennial erect, robust and tufted grass to 1.4 m tall. Stem nodes have downy hairs. Leaves are tufted at the base of the plant, usually glabrous, and densely hairy above reaching 30-50% of the stem length. Inflorescence up to 30 cm long in a dense panicle. Glumes purplish or green, 16–22 mm long. Lemma 7.5–9 mm long, pale or reddish brown at maturity. Hairs are semi-appressed, 0.6–2 mm long, that spiral and appear white to golden except toward apex. Palea about equal to lemma, with a line of hairs down the centre. Flowers September to December.[4]
Habitat
The plant grows in moist to dry soils, particularly in heathy woodlands. It is frost and snow tolerant and grows in full sun to semi shade.[5] Can be propagated by seed sown in autumn to early winter.[6] Occurs in a wide range of habitats with sandy and/or low fertility soils (e.g. coastal dunes and headlands, slightly saline flats, shrubland and dry eucalypt forest).
