Abstract:This paper shows that warty layers are not easy to be seen,or appear occasionally on the corner of inner surface of tracheids in Subgenus Haploxylon(Softpine)except Section Parry Mayr.but appear commonly on the inner surface of tracheids and the surface of pit border and pit chamber in Subgenus Diploxylon(Hardpine).It is an important characteristic of identification among subgenera,genera,and families in conifers.It is very easy to separate the warty layer from the neighboring layer,the inner layer or the outer layer of secondary wall in the part of pit border,and the inner layer of secondary wall. Warty layers are appeared clearly in the inner surface of tracheid and parts of pit in Pinus bungeana of Subgenus Haploxylon.It is very different from the other species of Haploxylon pines which have their own features.The author has made a systematic study and suggested to establish a new Subgenus Parry based on its gross and anatomical characteristics,ultrastructure,morphology of tree,and some aspects of chemotaxonomy.
