In species of Apium, Eryngium and Humulus, the cuticular membrane of the petiole could be resolved into two parts, of which the inner one appeared amorphous and after staining appeared to be penetrated by an electron-dense reticulum, whereas the outer layer showed a lamellate structure consisting of electron-dense and electron-transparent plates, 50-80 Å in thickness. These layers are considered to correspond with the cuticular layer and the cuticle proper, respectively. In species of Abutilon and Rumex the cuticle proper did not exhibit the lamellate structure. In the leaves of Eryngium the outer lamellated structure was present in the cuticle of both young and mature leaves. Both the lamellate and non-lamellate types of the cuticle proper increased in thickness with age of the specimen. The results are discussed in relation to earlier investigations.
在芹菜属、刺芹属和葎草属的物种中，叶柄的表皮膜可分为两部分，其中内层呈无定形，染色后似乎被电子致密的网状物穿透，而外层则呈现出由电子致密和透明的板组成的层状结构，厚度为 50-80Å。这些层被认为分别与表皮层和角质层相对应。在苘麻属和酸模属的物种中，角质层没有表现出层状结构。在刺芹属的叶子中，外层层状结构存在于幼叶和成熟叶的表皮中。角质层的层状和非层状类型都随着标本年龄的增长而增厚。结果与早期的研究有关。
