Definition
The term Coreopsis palustris is purported to refer to a plant species within the genus Coreopsis (family Asteraceae). However, reliable encyclopedic sources do not consistently recognize this binomial as a validly published or currently accepted species name.
Overview
Coreopsis is a well‑documented genus of flowering plants commonly known as tickseeds, native primarily to North America. Species within this genus are typically herbaceous perennials or annuals with yellow or orange composite flowers. The specific epithet palustris is Latin for “of marshes” or “growing in swampy habitats,” suggesting that, if the name were valid, the plant would be associated with wetland environments.
Because the name Coreopsis palustris lacks clear citation in major taxonomic databases (e.g., The Plant List, Tropicos, USDA PLANTS) and is absent from standard floras, its taxonomic status, distribution, and morphological description remain unverified.
Etymology / Origin
- Coreopsis: Derived from the Greek koris (κόρις, “bug”) and opsis (ὄψις, “appearance”), referring to the seed’s resemblance to insect eggs.
- palustris: A Latin adjective meaning “of marshes” or “growing in swampy ground,” commonly used in botanical nomenclature to denote wetland affinity.
Characteristics
Accurate morphological or ecological characteristics for Coreopsis palustris cannot be provided because the species is not confirmed in authoritative botanical references. If the name were to correspond to a distinct taxon, one could expect traits typical of the genus Coreopsis (e.g., opposite or alternate leaves, composite flower heads with yellow ligulate florets) combined with an adaptation to moist or periodically inundated habitats implied by the epithet palustris.
