Abstract
On the basis of morphological characteristics, liverworts have been divided into the Marchantioid group or “complex thalloids”, and the Jungermannioid group, which comprises two morphological subgroups, “simple thalloids” and “leafy hepatics”. These groups have been defined in the hierarchy of most classification schemes and have long been viewed as natural phylogenetic units (167, 732). The recent molecular phylogenetic studies have brought new insights to the systematics of liverworts and have greatly modified this morphology-based concept (337, 665). The new classification of the Marchantiophyta proposed by Crandall-Stotler and coworkers (168, 169) is presented in Table 1.1. Each underlined genus has been studied chemically previously.
