BRYOPHYTES FROM THE FIJI ISLANDS, VI The genus Cololejeunea Raddi (Jungermanniopsida), with the description of seven new species

摘要

The recent investigation of the Fiji Islands in the Pacific revealed many new records and the kno wn number of Cololejeunea species was raised from 10 to 38. One out of these fell in synonymy and another proved to be a new species. Altogether eight taxa are described here, as new to science: Cololejeunea bifalcata, C. blepharophylla, C. crateris, C. konratii, C. pacifica, C. saroltae, C. schmidtii var. acutepapillosa and C. tuiwawana. Hie aim of this paper, apart from the description of new species,includes the redescription of Cololejeunea polyantha and the lectotypification of Lejeunea polyantha (on which C. polyantha is based), and to provide a key for all the 43 species recently known from the Fiji Islands. Some new insular records are also added and finally a phytogeographical analysis on the Fijian Cololejeunea flora is made.
