摘要/Abstract

摘要： 利用光学显微镜和扫描电镜观察了猪笼草[Nepenthes mirabilis（Lour.）Druce]变态叶的表皮特征。结果表明：（1）叶片、瓶状体和瓶盖表面均具气孔器和星状毛，表皮细胞形态相似；（2）瓶盖下表皮和瓶状体下部内表皮密布腺体；瓶盖下表皮的腺体圆形并平覆于表皮上；瓶状体下部内壁腺体由“头部”和“外被”组成，并隆起于表皮上；（3）瓶状体口缘由纵向的细棱组成，细棱之间具袋状横纹；（4）瓶状体上部的内表皮平滑，表面形成拒水蜡层。

Abstract: Epidermal features of the modified leaf of Nepenthes mirabilis were observed with a light microscope and a scanning electron microscope（SEM），respectively. The results were as follows：① Stomata and stellate trichome were presented in the epidermis of leaf，pitcher and pitcher lid，and shape of all epidermal cells was similar. ② The round glands existed densely in lower epidermis of pitcher lid，while glands，as“head”and“cover”，humped in inner epidermis of bottom pitcher. ③ The peristome of pitcher consisted of longitudinal ribs，and corsswise bursiform markings occurred among the ribs. ④ The inner epidermis of upper pitcher was smooth and coated with a water-resistant wax layer.

Key words: Nepenthes mirabilis, leaf epidermis, gland, micro morphology
