Senecio glossanthus (nom français indéterminé)
- Nom local : Slender Groundsel
- Classification (Famille - Genre espèce) : Asteraceae - Senecio glossanthus
- Description : Référence Department of Primary Industries
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.
