New Records for the Bryophyte Flora of Vietnam, 5

Abstract

In November 1998, guided by Prof. Trấn Ninh we revisited the Tam Đảo mountain range, extensively researched by him before. Since than it was converted into a National Park, with areas stretching to three provinces, Vĩnh Phúc, Thái Nguyên, and Tuyên Quang. The previous collections indicated that many more novelties can be expected from there. As a result, we collected 38 epiphyllous liverwort species. Among these 6 were new to the flora of Vietnam: Cololejeunea fructu-marginata, C. papillosa, C. spathulifolia, Colura bisvoluta, Lejeunea dipterota and Microlejeunea sechuanensis. One species is new to science: Cololejeunea dinhensis. Furthermore, Cololejeunea rotundilobula proved to be a new synonym of Cololejeunea sigmoidea.
