Systematics of Cheilolejeunea (Spruce) Schiffn. (Lejeuneaceae) in Continental Africa and its Ecological Significance in Conservation of Kakamega and Budongo Rainforests

  • The genus Cheilolejeunea (Spruce) Schiffn. (Lejeuneaceae, Jungermanniopsida) is represented by 23 species in continental tropical Africa. The morphological characters such as features of the stem, leaf, lobule and perianth traditionally used to separate the taxa at both species and generic level have been found to be unstable. The species are variably ranked in several subgenera including Cheilolejeunea (Spruce) Schiffn., Euosmolejeunea Schiffn., Strepsilejeunea (Spruce) Schiffn. and Xenolejeunea Kachroo & Schust. Although the genus has never been monographed, there are a few regional taxonomic accounts for America, Australia and China. A comprehensive revision of Cheilolejeunea species is lacking in Africa where the existing studies are based on single subgenus and sub-regional flora or checklist compilations, which are sometimes without identification keys. This study revises the taxonomy of Cheilolejeunea and the closely allied genus Leucolejeunea A. Evans, in continental Africa based on morphological data analysed using phenetic and phylogenetic methods.
