Abstract
ABSTRACT Introduction. Syrrhopodon wallisii Müll.Hal. [≡ Mitthyridium wallisii (Müll.Hal.) H.Rob.], whose primary type material in B was destroyed during the Second World War, is lectotypified from among surviving original material, and its controversial interrelationship with its close relative M. crassum (Broth.) H.Rob. is investigated. Methods. Nomenclatural and taxonomic investigation was carried out with reference to bryological literature and herbarium material, including type specimens. It involved the microscopic investigation and analysis of leaf morphology in both historical and recent collections. Key results and conclusions. Mitthyridium wallisii is lectotypified with a specimen in the herbarium of E. Hampe (BM000662478). Based on morphological evidence, the Malesian moss taxa M. wallisii and M. crassum are likely to be distinct entities with the status of species.
期刊介绍：
Journal of Bryology exists to promote the scientific study of bryophytes (mosses, peat-mosses, liverworts and hornworts) and to foster understanding of the wider aspects of bryology.
Journal of Bryology is an international botanical periodical which publishes original research papers in cell biology, anatomy, development, genetics, physiology, chemistry, ecology, paleobotany, evolution, taxonomy, molecular systematics, applied biology, conservation, biomonitoring and biogeography of bryophytes, and also significant new check-lists and descriptive floras of poorly known regions and studies on the role of bryophytes in human affairs, and the lives of notable bryologists.
