Slender rhizomatous perennial herb to 37 cm high. Leaves forming tufts spaced along the rhizome, either terete or flat and strap-like, to 300 mm long and 3 mm wide, sheathed at the base with an obvious ligule at the top of the sheath to 5 mm long. Inflorescence an erect spike to 25 cm long, fruiting part at the top to 18 cm long with 20–200 fruits. Fruits are straw-coloured almost globular fruit to 2 mm long, on stalk to 3 mm long with six seed segments (carpels), 3 fertile alternating with 3 undeveloped sterile ones. Seeds are straw-coloured wedge-shaped seed to 2 mm long and 1.5 mm wide, with 3-ridged dorsally when dry, sterile seed segments remaining attached to the stalk when fertile ones have fallen. Seed embryo type is linear.
Seed collection and propagation
Collect seeds between August and May. Collect mature fruits either by breaking off individual spikes or by removing plants that are drying off with fruits that are straw-colour and seed segments coming apart easily. Place the fruit spikes in a tray and leave to dry for 1 to 2 weeks. Then rub the dried fruit spikes with a rubber bung to dislodge the seeds. Use a sieve to separate any unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. From two collections, the seed viability were average to high, ranging form 80% to 90%.
