Flowering March-May. Annual or perennial. Native.

One-sided racemes of cream to pinkish flowers on erect above-ground spikes, the calyx 4-lobed and glandular-hairy. Grows from underground rhizomes and has small, fleshy scale-like leaves. Lacks green colouring so cannot photosynthesize. Height 10-20cm.
