i suggest by wind. cz it is light and is small. i agree it does not have a wing-like structure but most of its features came to be same as seeds that disperse by wind.
water
Mature seeds are often very dry and need to take in water, before cellular metabolism and growth can resume. Seeds need enough water to swell and break the seed coat.

YES! The waxy coat of the water hyacinth leaves is waterproof and covers a spongy parenchyma tissue. Together with its swollen stem, which is filled with more spongy parenchyma tissue, it makes the plant float.

No , Seeds can germinate only by imbibing water. Oil come in the way for water permeation across the seed coat.
The parent plants want the seeds to go away from the parent plants so that their genes don't compete. That is why they will blow around or catch on a animals coat.
Seeds are dispersed by various agents like wind , water, animals and humanbeings.Winged seeds like drumstick and maple are carried by wind.Light seeds of grasses or hairy seeds of aak and hairy fruit of sunflower get blown away with wind to far away places.Some seeds are dispersed by water.These fruits or seeds ususlly develop floating ability in the form of spongy or fibrous outer coat as in coconnut.Some seeds are dispersed by animals, especially spiny seeds with hooks which get attached to the bodies of the animals and are carried to distant places.Examples are Xanthium and Urena.Some seeds are dispersed when the fruits burst with sudden jerks.The seeds are scattered far away from the parent plant. This happens in the case of castor and balsam. [Written by Rini Sebastian]

seed coat
Yes bean seeds are provided with very hard and impervious seed coat. Water enters in it through micropyle only. If the seed coat is removed (skinned), the hydrophilic proteins inside will absorb water at a faster rate.
Plants have an outer coat to protect the plant inside and keep it moist?
Sand, rasp, or nick the seed coat. Soak in water overnight, then plant.
