Leaf architecture of simple leaves (a) and dissected leaves (b) of A. thaliana and C. hirsuta respectively. The simple leaf consists of a single entire leaf blade and a petiole. The architecture of a dissected leaf is more complex. The leaf blade is divided into terminal and several lateral leaflets, which are arranged along the main axis, which itself consists of the terminal rachis, inter rachis and the petiole. The petiolules connect the rachis and the lateral leaflets
