The genus Typhonium Schott comprises more than 70 species with a vast geographic range, extending from Mongolia through tropical regions of Asia and reaching as far south as northern and eastern Australia.The genus consists of small, seasonal geophytic herbs with a (sub)globose tuber or short rhizome. Leaves vary in number and shape, ranging from simple to decompound with diverse leaflet forms. Inflorescences typically emerge after leaf development on a short or long peduncle. The spathe, ovate to lanceolate, is divided by a constriction below the staminate zone, with a limb often coloured pale to deep purple, rarely whitish or pinkish. The spadix includes a basal pistillate zone, a sterile zone with staminodes, a staminate zone, and a sterile appendix that varies in length, shape, and orientation, from erect to pendulous, narrowly conical to tail-like.
