Abstract

Pinus sylvestris var.mongolica,P.densiflora and P.tabulaeformis were Pinaceae,Pinus,Sect.Pinus of Subgen.Pinus.Their common characteristics were: two leaves in a fascicle,persistent sheath,two vascular bundles in needle-like leaf,but there were great differences on morphological features,internal structure of needle-like leaf and bio-ecological characteristics.According to these differences,three kinds of pine trees could be accurately identified.
