Plant description
Perennial sedge to 80 cm high, producing slender rhizomes bearing ellipsoid fibrous-coated tubers which give rise to new stems. Stems relatively slender, somewhat trigonous at the top; the remainder cylindrical, the base thickened. Leaves few, narrow, much shorter than the stems. Bracts at least 2 or 3, the lowest usually longer than the inflorescence and often suberect. Inflorescence umbel lax, often thrown to one side; usually simple of few very slender rays; spikelets fairly close together but not clustered; usually 3-8 to each ray, spreading, rich-brown to pallid, linear, to 3 cm long and 2 mm wide, many-flowered. Flowering between August and December. Fruits are brown fruit clusters at top of stems. Seeds are black long triangular seed to 2 mm long and 0.8 mm wide, with a reticulate surface. Seed embryo type is capitate.
Seed collection and propagation
Collect seeds between October and February. Collect fruits either by picking off the mature heads, those turning brown and come-off easily or breaking off whole heads. Place the heads in a tray and leave to dry for one to two weeks. Then rub the heads with a rubber bung to dislodge the seeds. Use a sieve to separate any unwanted material. Be careful, as the seeds are very small. Seeds are yellowish ovoid and hard. 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.
