Definition
Cyperus kappleri is a species of flowering plant in the sedge family, Cyperaceae. It belongs to the genus Cyperus, which comprises perennial, grass‑like herbs commonly referred to as flatsedges.
Overview
-
Taxonomic classification:
- Kingdom: Plantae
- Clade: Tracheophytes
- Clade: Angiosperms
- Clade: Monocots
- Order: Poales
- Family: Cyperaceae
- Genus: Cyperus
- Species: C. kappleri
-
Discovery and description: The species was formally described in the early 20th century by botanists studying tropical American flora. The original publication details are limited in publicly available sources; however, the name is recognized in botanical databases such as The Plant List and Tropicos.
-
Geographical distribution: Reported occurrences of Cyperus kappleri are primarily in northern South America, including regions of Venezuela, Colombia, and Brazil. It is typically associated with moist, low‑land habitats such as riverbanks, seasonally flooded savannas, and wet forest margins.
Accurate information is not confirmed regarding the full extent of its range or its precise ecological preferences. -
Conservation status: No assessment has been published by the International Union for Conservation of Nature (IUCN) for this species; therefore its conservation status remains undocumented.
Etymology / Origin
The specific epithet kappleri is a patronym honoring a person bearing the surname Kappler, likely a collector or botanist who contributed specimens or knowledge of the plant. The exact individual commemorated is not definitively recorded in the taxonomic literature.
Characteristics
- Growth form: Perennial herbaceous sedge forming clumps or spreading via short rhizomes.
- Culms (stems): Typically erect, slender, and triangular in cross‑section, characteristic of many Cyperus species.
- Leaves: Linear, grass‑like, arising from the base of the culm; the leaf sheaths are closed.
- Inflorescence: An umbel of several to many spikelets arranged at the apex of the culm; spikelets are usually laterally compressed.
- Flowers and fruit: Small, wind‑pollinated flowers lacking showy petals; fruit is an achene (nutlet) with a hard coat.
- Ecology: As a wetland‑associated sedge, it contributes to soil stabilization and provides habitat for aquatic invertebrates.
Detailed morphological measurements (e.g., culm height, spikelet length) for C. kappleri are not widely published; therefore precise diagnostic characters are unavailable in the current literature.
