1. (Bot.) A trailing branch which is disposed to take root at
   the end or at the joints; a stole.
2. (Zo["o]l.) An extension of the integument of the body, or
   of the body wall, from which buds are developed, giving
   rise to new zooids, and thus forming a compound animal in

   Bryozoa, and social ascidians. See Illust. under
