Other Common Name:



Native to Western Australia, South Australia, New South Wales, Northern Territory, Queensland and Victoria.

Plant Description:

An erect, sparsely hairy, ephemeral herb, 8–30 cm tall, and unbranched or few branched except for the
flower-heads. The mildly stem-clasping, leaves are lanceolate (spear-shaped) to broad-lanceolate, mostly 1–7 cm long and 3–10 mm wide, undivided or irregularly toothed or with 1–6 irregular lobes.

Inflorescence (flower-head) branched. Each 3-3.5 mm diameter flower is actually a composite of female, outer ray florets (‘petals’) and bisexual, inner tubular or disk florets. The whole bell-shaped, composite ‘flower’ is enclosed in an involucre, 3.5-6 mm long, consisting of 7-10 phyllaries. The fruit is a narrow-obloid achene, 1.8-3 mm long and more or less covered in hairs.


Largely confined to the far north-west of the State, growing in seasonally wet areas, such as Gilgai plains and clay pans but also in shrublands and woodlands. Appears to tolerate some salinity.


Similar to Salt Groundsel (
Senecio halophilus) which has until recently been included within the species. Slender Groundsel differs in having a smaller involucre and shorter achene hairs on the disc florets, and is not as salt tolerant.
