 It is possible that this may be an introduced plant on the west coast of Mexico as well 

 as elsewhere. I have seen it only in the immediate vicinity of towns where it is 

 almost invariably found in the hedges that line streets and roads. The fruit is exceed- 

 ingly viscid, adhering to everything with which it comes in contact, so that it might 

 easily be carried about by animals brushing against the plants or otherwise. The 

 viscidity is retained by the fruits for a very long time in herbarium specimens.
