Ixia dubia is a cormous perennial that grows to heights varying between 25 cm and 60 cm. Sword-shaped to linear leaves, about five to seven of them, are borne annually. The leaves become up to 50 cm long and 8 mm wide, while leaves of 10 cm by 1,5 mm are also seen.
The flowers grow spirally arranged in a compact spike on a wiry, usually unbranched stem. Three-toothed bracts, pinkish translucent and papery, are visible upon the stem below the flowers in picture. Up to ten flowers may grow upon a stem (Bean and John, 2005; Manning, 2007).
