Definition
Cyperus inaequalis is a binomial name that has been cited in botanical literature as a purported species within the genus Cyperus (family Cyperaceae). Reliable, comprehensive encyclopedic sources detailing this taxon are lacking, and its acceptance in current taxonomic databases is not confirmed.
Overview
The name appears sporadically in older floristic works and herbarium records, suggesting that it may have been described historically, possibly as a distinct species or as a synonym of another Cyperus taxon. Contemporary taxonomic references (e.g., the World Checklist of Selected Plant Families, Plants of the World Online) do not list Cyperus inaequalis as an accepted name, indicating that its status is uncertain or that it may be regarded as a nomenclatural synonym.
Etymology / Origin
- Genus name: Cyperus derives from the Greek “kypere” meaning “sedge,” a common name for members of the family Cyperaceae.
- Specific epithet: inaequalis is Latin for “unequal” or “irregular,” possibly referring to a morphological feature (such as unequal culm lengths, spikelet sizes, or leaf arrangements) observed in the original description.
Characteristics
Accurate morphological, ecological, or distributional information for Cyperus inaequalis is not confirmed. Consequently, specific characteristics cannot be reliably detailed. General traits of members of the genus Cyperus include:
- Herbaceous, grass‑like plants typically forming clumps or colonies.
- Stems (culms) that are often triangular in cross‑section.
- Leaves arranged in three ranks with a sheathing base.
- Inflorescences comprised of spikelets that may be dense or loosely arranged.
Without verified sources, it is not possible to state whether C. inaequalis conforms to these typical features or exhibits distinctive adaptations.

- Taxonomic synonymy – The practice of consolidating multiple names that refer to the same species, relevant for assessing the status of Cyperus inaequalis.
- Botanical nomenclature – Rules and conventions that govern the naming of plant taxa, as governed by the International Code of Nomenclature for algae, fungi, and plants (ICN).
Note
Due to the absence of corroborated, up‑to‑date encyclopedic entries, Cyperus inaequalis is not widely recognized as a distinct, accepted species in contemporary botanical literature. Further taxonomic investigation would be required to clarify its validity and to provide a comprehensive description.
