摘    要:对香青属Anaphalis所有两亚属、两组以及8个系,共19个种1个变种的叶片形态进行了研究.结果表明,香青属属下不同亚属和不同系之间叶片形态特征具有一定差异,而叶形、叶缘和叶脉特征在种间存在交叉;拟鼠麴亚属的单型种粘毛香青的维管束特征不同于香青亚属;在香青亚属中,球苞组3个系代表种的叶片木质化程度比珠光组4个系代表植物为高;珠光组的香青系和球苞组代表植物叶片的维管束两侧至表皮细胞之间,具有厚壁细胞或厚角细胞.

关 键 词:香青属  叶片  形态特征  解剖结构

Abstract:Leaf morphology and anatomy of nineteen species and one variety of Anaphalis,representing both subgenera,two sections and eight series,were investigated using light microscopy.The results showed that subgen.Gnaphaliops and subgen.Anaphalis differed in the characters of leaf base,while leaf shape,edge and vein were obliquitous among species.The characters of vascular bundle of A.bulleyana in subgen.Gnaphaliops differed from those in species of subgen.Anaphalis.Within subgen.Anaphalis,leaves of sect.Anaphalis held more lignified elements than those of sect.Margaripes.Leaves of sect.Margaripe ser.Sinicae and sect.Anaphalis bore one to several layers of sclerenchyma and collenchyma cells between vascular bundle and epidermis.
Keywords:Anaphalis  leaf  morphological characters  anatomical structure
