A helophyte is a plant that grows in marsh, partly submerged in water, so that it regrows from buds below the water surface.Fringing stands of tall vegetation by water basins and rivers may include helophytes. Examples include stands of Equisetum fluviatile, Glyceria maxima, Hippuris vulgaris, Sagittaria, Carex, Schoenoplectus, Sparganium, Acorus, yellow flag, etc.

Helophytes are plants that are adapted to live partly in water and partly above substratum and free from water. They are commonly found in wetlands and marshes.
Adaptations of Helophytes:
1. Root Adaptations: Helophytes have special root adaptations that enable them to absorb nutrients from both water and soil. Some of these adaptations include:
- Pneumatophores: These are specialized roots that grow vertically from the submerged stems of the plant and extend above the water level. They are filled with air spaces that allow oxygen to diffuse into the submerged roots.
- Adventitious roots: These are roots that grow from the stem or leaves of the plant and help to anchor it in the substrate.
2. Stem Adaptations: Helophytes have stem adaptations that help them to stay upright in the water and support their leaves and flowers. Some of these adaptations include:
- Floating stems: Some helophytes have stems that float on the surface of the water, allowing their leaves and flowers to be exposed to air and sunlight.
- Erect stems: Other helophytes have stiff, upright stems that rise above the water level and support their leaves and flowers.
3. Leaf Adaptations: Helophyte leaves have adaptations that allow them to survive in both wet and dry conditions. Some of these adaptations include:
- Hydrophobic surfaces: Some helophyte leaves have a waxy, water-repellent surface that prevents them from becoming waterlogged.
- Thick cuticles: Helophyte leaves may have thick, waxy cuticles that help to prevent water loss and protect them from desiccation.
- Stomata: Helophyte leaves have stomata that enable them to exchange gases with the atmosphere, allowing them to photosynthesize even when submerged in water.
Examples of Helophytes:
1. Cattails: Cattails are tall, reed-like plants that grow in marshes and wetlands. They have long, narrow leaves and a distinctive brown, cylindrical flower spike.
2. Water lilies: Water lilies are floating aquatic plants with large, round leaves and showy flowers. They are often found in ponds and slow-moving streams.
3. Bulrushes: Bulrushes are tall, grass-like plants that grow in wetlands and along the edges of lakes and streams. They have long, narrow leaves and a distinctive brown flower spike.
