 species. The affinities are with the Juglandaceae, 

 which Order includes the Walnut. 



They are found in Temperate and Tropical Asia, 

 South Africa, and North America. 



They are shrubs or trees, some having a glandular,

 being achlamydeous. The male flowers possess two 

 to sixteen stamens, sometimes monadelphous, the 

 anther-stalks being attached to the base of the bract,
