Bulb broadly ovoid, 2–6 cm diam. Leaves several, linear, flat, 10–50 cm long, 5–10 mm wide, developing as fruits mature. Scape cylindric, erect, to c. 50 cm high. Umbel 20–30-flowered; spathe-bracts 2, one is usually bilobed, 3–6 cm long; pedicels to 50 mm long; flower golden to greenish yellow, sometimes pink near base, tubular in lower 6–12 mm, lobes spreading, ovate, 14–18 mm long; corona 9–12 mm long, yellow or pink, truncate or lobed between stamens; free part of filaments 2-5 mm long.

MuM, MSB. Localised in the far north-west, known only from a single population on the Murray River floodplain west of Merbein, common in drainage systems of the Darling River in New South Wales and Queensland, and the Murray River floodplain in South Australia.

Intergrades between this species and C. purpureum are common along the Murray River, with various colour forms often produced (Lang 2008). Calostemma luteum is sometimes regarded as a synonym of C. purpureum. However, C. luteum can be distinguished by the generally larger flowers with more widely spreading lobes and predominately yellow flower colour, and fewer scape bracts.
