When ripe and ready to fly, the brush-like or fluffy Linzia glabra fruits are held together at the base by the involucre. It is from here that the bristles radiate, all of about the same length.

These bristles are greyish white, the involucres beige with brown-tipped bracts that will release the fruits on the wind in dispersal for the seeds to start a new life somewhere (iNaturalist; http://pza.sanbi.org).
