Goat's beard seed. A parachute-borne seed leaves the seedhead of a goat's beard or Johnny-go-to- bed-at-noon plant,Tragopogon sp. Each individual seed is attached to a parachute of fine hairs,known as a pappus,which is lifted from the seed head and carried away by the wind. This type of seed dispersal is typical of the Compositae,the family of plants to which the goat's-beard belongs | |
