COKNACEAE 267 



About 50 species in the northern hemisphere. The bark, leaves and 

 fruit are used in medicine for their astringent and tonic properties. The 

 genus is highly ornamental. A large number of species have an inflores- 

 cence accompanied by showy petal-like bracts which makes the tree 

 extremely attractive in bloom. The brightly colored stem and twigs of 

 some shrubby species render them desirable as decorative subjects.
