Family PlNACEAE. Conifer Family. 



An ancient family of relatively few chiefly evergreen genera 

 and species, but these widespread and often very numerous in 

 individuals forming conifer forests of large extent and furnish- 

 ing the principal "soft woods" of temperate regions. Largely 

 employed for windbreaks and evergreen effects ; characteristically 

 trees, but likely to occur in shrubby form.
