Pinus Bungeana is a very distinct species readily recog- 
-nised in old examples by its white flaking bark; when 
young, however, the bark is dark smoky-brown with dull 
greyish patches where it has flaked off. It is specifically 
most nearly allied to P. Gerardiana, Wall., from which it 
is distinguished by its whiter bark, rather shorter and 
somewhat stouter leaves, and male catkins that form a 
compound terminal spike instead of being clustered below 
the apex of the branchlets. These two species, with 
P. chihuahuana, Engelm., and P. Lumholtzii, Robins. & 
Fern., form a small group which the late Dr. Masters looked 
upon as distinct from the other species of the genus owing 
to the deciduous leaf-scales and the leaves in bundles of 3 
with minutely serrulate margins.
