It is an ascending or erect annual. The plant normally grows to about 60 cm in height, and is usually simple or few-branched. Inflorescence bracts are papery and golden-yellow in colour.[8] It has thin, fleshy roots with a mean maximum diameter of 2mm.[9]

Seedlings are tolerant of existing adult competition.[10] Its post-fire regenerative strategy is by both seed and sprout.[9]
