Ficinia nodosa, a grass-like sedge, grows to roughly 100 cm in height, with its smooth, green-yellow stems spreading up to 200 cm in diameter. The stems themselves grow between 15 to 100 cm in length and 1 to 2mm in diameter. The flowers of Ficinia nodosa appear as brown-orange clumps just below the tip of the stems, with hemispherical spikelets of 7-20mm in diameter sitting underneath a bract. The fruit, found within the flower-heads, are an irregularly shaped dark brown to black nut with a diameter of approximately 1mm. Ficinia nodosa flowers in the summer season of the Southern Hemisphere, between September and December, while the seeds appear for a longer period between November and May. Despite flowering in the summer months, the seedhead is often retained year-round. Ficinia nodosa is distinguished from similar plants such as those of the genus Isolepsis due to Ficinia nodosa’s larger growth patterns and rigid, wooded stems.
