The fruits of various species of Zizyphus are largely eaten in the 
Orient, particularly those of the jujube (Z."Jujuba). 
Some of the woody climbers belonging to this family are respon- 
sible in the tropics for the impenetrable jungle of vegetable ropes or 
lianas which must be cut apart before a path can be made. In the 
West Indies and on the Florida Keys, Gouania Domingensis is an 
example. The photograph (Fig. 142) shows the clusters of small flow- 
ers and the tendrils by which the plant climbs. Throughout our South- 
ern States the supplejack (Berchemia volubilis) is conspicuous in swamps, 
its slender rope-like stems possessing a wonderful degree of tenacity.
