The Actinidias hold somewhat the same position in the vegetation of the 
Far East that the brambles do in this country—that is to say, they provide a 
large part of the shrubby growth in wood borders and in hedges, in districts 
in which they abound, climbing over small trees when occasion offers or 
forming large straggling bushes on the hill-sides. Their long weak shoots 
do not, however, as in the case of the brambles, hook themselves on to their 
supports by means of thorns, they rather elbow their way by means of short 
divergent side branches until they find access to the light above them. Аз in
