genera have a few valvate or peltate scales on a depressed axis. 

 Ovules erect, two or more, seldom one. 



Among the Cupressmeee we rarely find lofty trees as under 

 Abietinese. The Cupressineas are all evergreen (the " deciduous 

 Cypress," Taxoclium distichum, which in former days was 

 termed a Cupressus, does not belong to this tribe, but to the 

 Taxodie^e), and none of them have the leaves arranged in whorls, 

 as is the case with the Pines. A greater part of the species are 

 natives of warm climates, and of the genus Cupressus itself 

 only a few species are really hardy in Northern Europe. The 

 common Juniper alone is indigenous to Northern Europe.
