猪笼草叶的形态解剖结构研究

对猪笼草 (N epenthes mirabilis)叶进行形态、解剖学的观察和研究 ,结果表明猪笼草的叶是一种变态的单身复叶。其基部的两个侧生小叶与总叶柄合生 ,总叶柄顶端扩大反卷为瓶状体 ,瓶状体一侧也有 2片附生小叶 ,顶生小叶与总叶柄连接处有关节 ,关节上还有 2～ 5片退化的小叶

Studies on the anatomical structures of the leaf of Nepenthes mirabilis (Lour.) Druce

WT5”BZ] The results of its morphological and anatomical observation and studies on the leaves of Nepenthes mirabilis (Lour.) Druce indicate that its leaves are a kind of metamorphosis unifoliates; with a symphysis of rachis and two lateral leaflets at the base. The tip of rachis enlarges and turns back into flask like body, on one side of it growing two leaflets, and the tip growing leaflet changes its form into the cover of the flask; There are joints where the cover joins the flask like body; and on the joints there are still two to five (2～5) reduced leaflets.
