During our visit to the Tam Đảo National Park in 1998, with the guidance of Prof. Trần Ninh, we collected a peculiar Bazzania species unknown from Vietnam before. This species, with its incurved, fragile leaf apices and deeply dissected underleaves proved to be new to science. This paper provides its illustrated description. [ABSTRACT FROM AUTHOR]

The genus Diplasiolejeunea is added to the liverwort flora of India from the Kerala part of the Western Ghats reporting two species: Diplasiolejeunea cavifolia Steph. and D. cobrensis Gottsche ex Steph. The genus is known from tropical Asia with eight species. Among them Diplasiolejeunea cavifolia is widespread, but still the genus was not yet recorded from India. [ABSTRACT FROM AUTHOR]

A liverwort collection by Bence Pócs from the Venezuelan Guayana resulted in 31 species of liverworts, including Cololejeunea bencei new to science and C. cardiocarpa, C. obliqua, C. platyneura, C. schusteri, C. verwimpii, Lejeunea pulchra and Plagiochila crispabilis new to Venezuela. The distribution and differentiation of C. schusteri is discussed. [ABSTRACT FROM AUTHOR]

Drepanolejeunea clavicornis and D. friesii were previously synonymised with D. physaefolia or all of them with D. vesiculosa. In the meantime, Drepanolejeunea vandenberghenii was described from the same species group, as new. In this paper many African specimens are compared with the original descriptions of the above species. Morphological investigations of these and their distributional patterns suggested that the former synonymisation was not justified. In addition, a new, rheophytic species from the same group: Drepanolejeunea vanderpoortenii, is described, as new to science. As a result, from the taxa related to Drepanolejeunea vesiculosa, now six species are recognised from Africa, including its Indian Ocean islands. For these 6 morphotaxa an identification key is provided. The results need confirmation by a future molecular analysis. [ABSTRACT FROM AUTHOR]

Examination of about one hundred unidentified Colura specimens resulted in new distributional data of eleven uncommon species, C. australiensis, C. bicornis, C. calyptrifolia, C. crispiloba, C. cristata, C. heimii, C. humbertii, C. imperfecta, C. obesa, C. rhynchophora, C. saroltae and a new species of sect. Colura from Madagascar, C. cataractarum. [ABSTRACT FROM AUTHOR]

After the examination of the Cryptogam collection in the Herbarium of the University of Science, Vietnam National University Ho Chi Minh City (PHH), 25 species proved to be new to Vietnam, including one hornwort and 24 liverworts. Among them, four genera: Denotarisia Grolle, Gongylanthus Nees, Leiomitra Lindb. and Lepicolea Dumort. are new records for the country. Diagnostic characters and illustrations are given for some taxa, as well as locality notes and habitat descriptions are provided for each collecting area. [ABSTRACT FROM AUTHOR]

Zoopsidella grahamii sp. nov., related to the Australasian Z. caledonica, is described from the Andes of Central Peru (Oxapampa Province) and southern Ecuador. It is distinguished from Z. caledonica by the smaller plant size, much lower number of lobe cells and different leaf shape, and by the much more elongate perianth mouth lobes consisting of a row of 6-7 narrowly rectangular cells. Riccardia gradsteinii sp. nov., from the same general area in Peru as Z. grahamii, is unique among all dendroid species of the genus by the broad, frilled wings of the main axis, being split into complicatedly bent and strongly crispate scales.
