Clematis is a terrestrial plant and its fruits are dispersed by wind. Clematis fruits show persistent hairy styles which help in dispersal by wind.
Typha is a terrestrial plant and its fruits are dispersed by wind. Long, thin, slender hairs are present on one end of its fruit which help in dispersal by wind.
Elm is a terrestrial plant. Elm seed pericarp is free from testa which forms a wing like structure. This structure helps in seed dispersal.
Nymphaea is also called as water lily. Seeds of Nymphaea can float on water as they possess aril which contains air between seed coat and embryo. Such air cavities are required for floating of seeds and fruits.
