Besides their similar morphology, graminoids share a widespread occurrence and often dominance in open habitats such as grasslands or marshes. They can, however, also be found in the understory of forests. Sedges and rushes tend to prefer wetter habitats than grasses.
The word graminoid is derived from Latin grāmen 'grass; herb', with the suffix -oid denoting '-like; resembling, characteristic of'.
