resin canals, and fine serrations on the edge of the leaf. Branchlets with more or less white powder. Male cones are light reddish yellow, clustered in the lower part of new branches, female cones are light reddish purple, solitary or clustered in two to three clusters. The cones are dark brown yellow or light brown yellow when mature, they dehiscent at maturity, seed scales usually thin, seed winged. The bark is orange-red, cracked into irregular scale-like pieces. Heartwood reddish brown, sapwood light reddish yellow. The height of the tree is . The crown can reach .
"The distribution of ''P. densiflora'' in China has the following pattern of variation: the more northward it is distributed, the needles are relatively shorter, the white powder on the branchlets is sometimes less obvious or partly obvious, and the color of the cones is lighter. It is light brown yellow".
The
