Cyperus javanicus
species of plant
Cyperus javanicus, also known as the Javanese flatsedge, is a sedge of the family Cyperaceae that is native to Indonesia and Australia.
Description
The rhizomatous glaucous perennial sedge typically grows to a height of 0.6 to 1.2 metres (2.0 to 3.9 ft) and has a tufted habit. The plant blooms between January and August producing brown flowers. The culms are obtusely trigonous and densely papillose. The leaves are long and flat on top while folded at the base and around 2 to 13 millimetres (0.08 to 0.51 in) in width. The compound inflorescences have between six and twelve primary rays which are up to 8 cm 8 centimetres (3.1 in) in length./>
Taxonomy
The species was first formally described by the botanist Martinus Houttuyn in 1782 in the work Natuurlijke Histoire of Uitvoerige Beschryving der Dieren, Planten en Mineraalen. Several synonyms have been described including: Cyperus pennatus Lam. in 1791, Cyperus canescens Vahl in 1805, Cyperus javanicus subsp. armstrongii Dunlop in 1987, Mariscus pennatus (Lam.) Domin in 1915, Cyperus ventricosus R.Br. in 1810 and Mariscus albescens Gaudich.
Begin with the source’s own compact description: “Cyperus javanicus” is species of plant. The dossier treats that line as a proposition to test through Cyperus, javanicus 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.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jun 28, 2025. The linked authority identifier is Q3008826. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1782, 1791, 1805 and 1987.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
