146. Oxydendrum arboreum (L.) DC. Sour Wood. 



A small tree with shiny, pointed, elliptic leaves 

 which have a decidedly sour taste. The small, white, 

 sweet-smelling flowers are formed on finger like race- 

 mes which are grouped at the ends of branches in 

 summer. They remind one of Lily of the Valley 

 and make a very attractive centerpiece with ferns. 

 Bees seek them and from them make the esteemed 

 sour-wood honey. The tree is scattered plentifully 

 through most of our woods from the mountains (un- 

 der 4000 feet) through the Piedmont, then retiring 

 to bluffs of streams and descending to the coast
