Glochids
Glochids (Greek glochís ) are fine, bristle-like thorns that are barbed and easily peel off when touched. Glochids are typical of the plant genus of Opuntia ( Opuntia ). They can also appear in large groups. An example of this is the species Opuntia microdasys .
The stalked barbs on the surface of the buoyant microspore balls in Azollaceae are also referred to as glochids.
