It often displays red colouration.

It is a monoecious species with bisexual reproductive units ("flowers"). The several, sessile reproductive units have 2–4 lanceolate, 2–3 mm long involucral bracts, 1–2 stamens with 0.6–1.0 mm long anthers attached to up to 1.5 mm long filaments, as well as 6-20 carpels. The ovoid-trigonous, 0.4 mm long, and 0.2 mm wide fruit with three prominent ribs is indehiscent, or at least in one case dehiscent. The ovoid, 0.3 mm long, translucent seed with a dark apex is smooth. Flowering occurs from April to June.Trithuria lanterna D.A.Cooke. (n.d.). Atlas of Living Australia.
