What kind of seeds have hair?

Seeds with hair, often referred to as "hairy seeds," typically belong to certain plant families such as the Asteraceae (daisy family) and some species within the Fabaceae (legume family). These hairs, or trichomes, can aid in wind dispersal, helping the seeds float or cling to animals. Examples include dandelions, which have fluffy, hair-like structures called pappus that facilitate wind dispersal. Additionally, some legume seeds may have fine hairs that assist in attachment to soil or other surfaces.
