Erect herb to 50 cm high, growing annually from a thickened persistent rootstock, with woolly or cobwebbed stems. Leaves scabrous to glabrescent, margins flat to revolute with basal leaves lanceolate to oblanceolate, to 20 cm long, and 20 mm wide and cauline leaves linear to linear-lanceolate, to 20 cm long and 15 mm wide, stem-clasping. Inflorescence large yellow hemispherical daisy head to 40 mm across at terminal of a long coppery stem. Involucral bracts with linear, glandular claws; lamina more or less ovate, scarious, virtually flat, smooth, shiny, apex acute to acuminate; intermediate bracts to 18 mm long, with claws shorter than the lamina; inner bracts long-clawed. Flowering between August and November. Fruits are white fluffy daisy-head. Seeds are cream to brown ovoid to oblong seed to 3 mm long and 1.5 mm wide, covered in small tubercules, with long feather-like pappus at one end. Seed embryo type is spatulate fully developed.
Seed collection and propagation
Collect seeds between October and January. Collect heads that are fluffy. Either pick off the whole heads or use your finger and pull off the seeds from the head. Mature seeds will come off easily. Place the heads in a tray for a week to dry. No cleaning is required if only pure seeds are collected. If heads are collected, then rub the heads gently with your hands to dislodge the seeds. Viable seeds will be fat and hard. Use a sieve to separate the unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. Seed viability is high for this species but can have high seed predation. Seeds are non-dormant, viable seed should germinate readily.
Obligate re-spouter and re-seeder.

In 2020-2021 this species was assessed post-fire in 1 year and 2 year old fire scars. A total of169,800 seeds have been collected & banked for 2 populations inside the 2020 fire scar. Germination screening testing the response to fire cues will be undertaken in 2021.This project was supported by the World Wildlife Fund program.
