These are called achenes, and each achene is an individual fruit containing a single seed.
Above the ground she stores it in drupe and pome and berry, nut and nutlet and achene, and below the ground in rootstock and rhizome, corm and tuber, pumping them full with strokes quick and strong in these grand climacteric days of the summer.
Fruit: A small achene tipped with long feathery white bristles
Fruit a trigonous, biconvex, or biconcave achene; seed with straight or curved embryo and copious endosperm.
This structure allows dispersal of the achene, a single seed produced by each female flower, to other sites by clasping to the hairs, or feathers, of any animal (or hairy tramper) passing by.
Fruit is red to brown achene with soft white hairs that helps in wind dispersal.
