Ficinia nodosa
species of plant
Ficinia nodosa, the knotted club-rush or knobby club-rush, is a rhizomatous perennial in the family Cyperaceae, native to South Africa, Australia, and New Zealand. Widespread in the Southern Hemisphere, Ficinia nodosa grows to between 15 and 220 cm in height.
Although it grows best in sandy, salty soil, the plant grows in a wide variety of environments from coastal sand dunes to alpine regions. F. nodosa’s appearance is characterised by dense clusters of long green stems topped with small, rounded flowers often remaining throughout the year.
Description
Ficinia nodosa, a grass-like sedge, grows to roughly 100 centimetres (39 in) in height, with its smooth, green-yellow stems spreading up to 200 centimetres (79 in) in diameter. The stems themselves grow to between 15 and 100 centimetres (5.9 and 39.4 in) in length and 1 to 2 millimetres (0.039 to 0.079 in) in diameter. The flowers appear as brown-orange clumps just below the tip of the stems, with hemispherical spikelets of 7–20 millimetres (0.28–0.79 in) 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 1 mm. 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. The seedhead is often retained year-round.
Begin with the source’s own compact description: “Ficinia nodosa” is species of plant. The dossier treats that line as a proposition to test through Ficinia, nodosa and species, not as a finished interpretation.
Why this record matters
The phrase “species of plant” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jun 22, 2026. The linked authority identifier is Q5446508. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
