Schoenus selinae
species of flowering plant in the sedge family (Cyperaceae)
Schoenus selinae is a species of sedge endemic to the Western Cape Province and western areas of the Eastern Cape Province of South Africa.
Description
Schoenus selinae is species with lateral papery extensions on its inflorescences (flowering stems), and it generally prefers wet mountainous habitats. The inflorescences usually have more than one cluster of spikelets, but when it does have only one spikelet cluster, it can resemble Schoenus pictus. The main differences between the two species is that S. pictus has leaves that arise from the base of its stems, whereas S. selinae lacks this character.
Schoenus pseudoloreus is a second species that resembles S. selinae, but the two differ in that S. pseudoloreus has leaves at the base of the stems, whereas the latter species lacks these leaves.
Other closely related species that lack leaves at the base of their stems and resemble S. selinae are Schoenus lucidus and Schoenus neovillosus. Whereas the culms and inflorescences of S. lucidus and S. neovillosus are partially hairy, S. selinae lacks hairs. Furthermore, the inflorescence bracts of S. selinae have membranaceous paper-like extensions, which are lacking in the other two species.
Similarities also exist between S. selinae and Schoenus rigidus, as both species have membranaceous paper-like extensions associated with their inflorescence bracts. The shape of the inflorescence of S. rigidus is more branched with the paper-like extensions only at the base of the spikelet clusters, whereas these extensions are present along a greater portion of the inflorescence length in S. selinae.
Begin with the source’s own compact description: “Schoenus selinae” is species of flowering plant in the sedge family (Cyperaceae). The dossier treats that line as a proposition to test through Schoenus, selinae and species, not as a finished interpretation.
Why this record matters
The phrase “species of flowering plant in the sedge family (Cyperaceae)” 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 Nov 13, 2024. The linked authority identifier is Q115103979. 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 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
