Résultats taxonomiques de l´éxpédition Bryotrop au Zaire et Rwanda : 30., bryophytes épiphylles (récoltes de E. Fischer)
- The author provides an annotated list of epiphyllous bryophytes collected by Dr E. Fischer in Kivu and Rwanda. Most of them belong to the Lejeuneaceae, but some other hepatics and mosses are also represented. A total of 101 hepatics and 17 mosses are reported. In this very important material, 13 new species and 2 varieties for science or for Africa were found: Cololejeunea cardiocapioides , C. fischerii , C. heterolobula , C. kahuziensis , C. lobulolineata , C. pseudo-obliqua , C. pseudo-pusilla , C. sphaerocarpa , C. tenui-parietata , C. tribracteata , Diplasiolejeunea cyanguguensis , C. gradsteinii , Harpalejeunea fischerii , Cololejeunea harrisii Pócs var. magna, and Drepanolejeunea symoensii (Vanden Berghen) Grolle var. minor. Some observations and ideas are given for Cheilolejeunea, in preparation for a future monograph of the genus in Africa and the Mascareno-Malagassy region. Drepanolejeunea , based on the author’s analysis is relatively depauperate in Africa (where some of the species are South East Asian taxa). The study of the genus was complicated because of the use of perianth characters in taxonomical delimitation. However, perianths are seldom encountered and are very variable. In Cololejeunea , the author builds on his earlier works on the genus in different regions and particularly in Madagascar. Some taxa were insufficiently defined and the author tries to separate the different species. The application of subgenera in Cololejeunea remains difficult. For example, C. platyneura is a member of the subgenus Taeniolejeunea, but may be confused with members of subg. Cololejeunea.
