A graminoid is a grass, or grass-like plant. The leaves are typically blade-shaped, and the flowers are plain by human standards.
- True Grasses – Poaceae
- Sedges, bulrushes – Cyperaceae
- Rushes- Juncaceae
- Cattails – Typhacea
Not botanist completely agrees on what a graminoid is for instance some exclude the cattails for instance. Graminoids grow pretty much everywhere other plants do on land; from hot deserts, to wetlands, forests, tundra and of course grasslands. Most graminoids are pollinated by the wind and distribute their seeds by dropping them next to the parent plant. There are always exceptions to the rule in nature though.
Many if not most of the most numerous emergent wetland species are graminoids: Phragmites, wild rice, burreed and tussock sedge are just a few examples. Without graminoid wetlands and other ecosystems would be very different.
