with effective white variegation and valuable also for

WEEPING. The pendulous trees of special value in 

 the garden are the Weeping Birch (Betula alba pendula 

 Toungi), Cut-leaved Weeping Birch (B. a. lacinata pendula), 

 Weeping Thorn (Cratagus Oxycantha pendula), Weeping 

 Ash (Fraxinus excelsior pendula), American Weeping 

 Willow (Salix americana pendula), a quite small tree with 

 elegant greyish leaves. Kilmarnock Weeping Willow 

 (5. caprea pendula), a handsome form with large leaves and 

 the Camperdown Weeping Elm (Ulmus campestris pendula). 

 For small gardens the Weeping Birch, the Kilmarnock 

 Weeping Willow and the Camperdown Weeping Elm 

 are preferable, while the Weeping Ash is the best when 

 it is desired to form a living arbour.
