摘要

In the present study, micromorphological and anatomic characteristics of 3 Pinus L. taxa (Pinus henryi, P. massonianaand P. tabulaeformis) were compared. These taxa have both endemic and limited distribution in China. For themicromorphological studies, the pollens were examined using light microscopy (LM) and scanning electron microscope(SEM). For the anatomical studies, needle anatomy characteristics of the 3 taxa were studied. After the studies, newcharacteristics of corpus exine ornamentation had been found. Spiny on the regulate of corpus exine is presented in P .henryi while baculate on the rugulate of corpus exine is existed in P. tabuliformishave. However, there is not ornamentationon rugulate in P. massoniana. The features of pollen size, corpus exine ornamentation, number of microperforations,cappula ridges are significant to distinguish the 3 taxa. Number of resin canals, stomatal rows, epithelial cells and sheathcells, dimensions of cross section, dimensions of resin canals and width of needle are also important in separating these taxa.These studies give taxonomic support for recognizing P. henryi as an independent species closely related to P. massoniana.

TabulaeFormis）的微观和解剖学特征。这些分类群在中国有流行和有限的分销。对于实例研究，使用光学显微镜（LM）和扫描电子显微镜（SEM）检查花粉。对于解剖学研究，研究了3个分类群的针解剖特征。在研究之后，发现了语料库的新特征。在p.henryi中呈现出肠道细胞的调节的刺在p.heNryi上搅拌在p. tabulificishave中的诱惑中。然而，没有植物在P. Massoniana毒毒性。花粉大小的特征，毒品胶囊装饰，微型次数，爪子脊的数量很重要，以区分3个分类群。树脂管数，气孔排，上皮细胞和鞘纤维，横截面的尺寸，树脂运河的尺寸和针的宽度在分离这些分类时也很重要。这些研究为识别p. henryi作为密切相关的独立物种提供分类管理。到P. Massoniana。
