Description

A rhizomic herb growing to 60cm. Leaves are 5 - 12 cm by 4 - 15 mm and somewhat toothed. Lower leaves are stalkless, while the bases of the upper leaves protrude beyond the stem (auriculate). The inflorescence is non-radiate with 5-20 heads of 40-70 florets surrounded by 16-21 bracts. The bracts end in a 'sort of curved spike', which distinguishes the species from S. argutus in the original description.

Distribution

Only one record from NSW, dated 1819, from the "Port Jackson" area, written of in "Sertum Astrolabianum. Voyage de Decouvertes de l'Astrolabe. Botanique 2: 107". The text accompanying the description states "New-Holland which commonly increases at Port Jackson, where Foncenexs disclosed. and a close friend of Gaudichaud." Freycinet was travelling through Bass Strait prior to this, and likely collected the plant there, this could be a source of the record generally listed as "Port Jackson". Additionally, as mentioned in the relevant recovery plan, there was travel between Port Arthur and Port Jackson, and the 'a close friend of Gaudichaud' suggests someone may have given him the specimen while at Port Jackson.
