Definition
Cyperus constanzae is a species of flowering plant belonging to the sedge family, Cyperaceae.
Overview
The taxon is reported from the Caribbean region, with documented occurrences on islands such as Cuba and the Dominican Republic. It typically inhabits wet or seasonally inundated environments, including marshes, riverbanks, and moist savanna margins. Like other members of the genus Cyperus, it is a herbaceous perennial that forms clumps or spreads via rhizomes.
Etymology / Origin
The specific epithet constanzae is derived from the proper name “Constanza.” In botanical nomenclature this often denotes a geographical reference; the name most likely honors the town of Constanza in the central highlands of the Dominican Republic, where the species may have been first collected. The exact reasoning behind the epithet has not been explicitly recorded in the original description.
Characteristics
- Growth form: Perennial sedge forming grass‑like tufts; precise stature and culm dimensions are not definitively recorded.
- Leaves: Typical Cyperus leaves are linear, basal to the culms, and sheathed; specific leaf length and width for C. constanzae are not confirmed.
- Inflorescence: The genus is characterized by an umbel of spikelets; the arrangement and number of spikelets in C. constanzae have not been fully detailed in accessible literature.
- Reproductive features: Flowers are unisexual, lacking showy petals, and produce achenes; detailed morphology of the achenes for this species is not publicly documented.
Accurate information is not confirmed for many of the finer morphological traits, as comprehensive taxonomic treatments or floristic monographs covering this species are limited or not readily available in major databases.
