What does hydrophyte mean?
A hydrophyte is a plant that grows in water or in a permanently waterlogged environment. The term includes submerged plants, such as pondweeds and water lilies whose leaves or stems remain below the surface, as well as floating and emergent species. Hydrophytes have specialized adaptations that help them cope with an aquatic life, including reduced supporting tissues, flexible leaves or stems, and specialized gas exchange. The word is most common in botany, ecology, and habitat management, where it is useful for distinguishing plants adapted to wet environments from ordinary terrestrial vegetation. In less technical contexts, aquatic plant or water plant may be used instead. Understanding hydrophytes is important for identifying wetland communities and describing the vegetation of ponds, lakes, marshes, and slow-moving rivers.
nounA plant that grows in water, typically with adaptations for an aquatic or waterlogged environment. Hydrophytes may be submerged, floating, or emergent and are rooted in the substrate or free-floating.
- A plant adapted to living in water or a waterlogged habitat, including submerged, floating, and emergent plants.
"Water lilies and pondweed are common hydrophytes in freshwater habitats."
"The lake's shallow edges support a rich community of hydrophytes."
"Botanists identified the submerged hydrophyte as a new species."
The regular plural is hydrophytes.
"Several hydrophytes grow along the marsh's edge."
A hydrophyte is a plant that has turned life in water into a specialized survival strategy.

Where does hydrophyte come from?
The word combines the Greek hydro- meaning “water” with the combining form -phyte, from Greek phyton, meaning “plant.” The term developed in botanical and ecological usage to refer specifically to plants adapted to aquatic habitats. Its components are also found in related scientific words such as phytoplankton, while the paired contrast is with xerophytes, plants adapted to dry conditions.
How hydrophyte is actually used
Hydrophyte is primarily a scientific and ecological term. In general writing, aquatic plant is often more accessible. The related adjective is hydrophytic.
Easily confused with hydrophyte
A hydrophyte grows in water, whereas an epiphyte grows on another plant or object for support without taking nutrients from it.
