New liverworts from the Peruvian Andes, II. Zoopsidella grahamii and Riccardia gradsteinii (Marchantiophyta)

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

Southern Thailand bryophytes II

Abstract The collection of epiphyllous bryophytes in the lowland rainforests of Phang-Nga province and in the neighbouring Phuket and Surat Thani provinces resulted in 54 liverwort and one moss species, of which 14 are new records for the bryoflora of Thailand. Epiphyllous bryophyte assemblages from nine localities are evaluated for species richness and beta diversity, as well as for their phytogeographical status

New or little known epiphyllous liverworts, XXII. Reinerantha (Lejeuneaceae), a genus new to Venezuela

Reinerantha foliicola was recently described as a new epiphyllous genus and species in the Cololejeuneinae subtribe of the liverwort family Lejeuneaceae, from the montane rainforest region of Ecuador. A second locality of this unusual plant was detected in Venezuela in a rich Andean montane rainforest near Mérida, at an elevation of 2,300 m

Epiphyllous Liverworts from Batanta Island (Indonesia, West Papua) III

The epiphyllous liverwort collection was continued after the Covid pandemic in 2023 at the low and medium elevations of Batanta Island in the tropical rainforest belt by the entomolo-gist Tibor Kovács and his colleagues, which were identified by Tamás Pócs. The collection resulted in 35 species of which 9 liverworts proved to be new to Batanta Island along the species already known from the previous collections: Cheilolejeunea trapezia, Cheilolejeunea vittata, Cololejeunea schmidtii, Cololejeunea tenella, Colura herzogi, Drepanolejeunea cyclops, Leptolejeunea maculata, Microlejeunea punctiformis , and Radula javanica . Further three taxa are new even to science: Cololejeunea tiberii, Cololejeunea touwii subsp. batantae subsp. nov. and Drepanolejeunea levicornua var. incurviloba var. nov., which were described and illustrated by macro and microphotos. One previous identification was corrected. The results of 7 years of collecting activity resulting in 48 epiphyllous liverwort taxa known from Batanta Island are summarised

New records for the liverwort and hornwort flora of Vietnam, 1

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

Notes on four new and noteworthy records of Lejeunea from Meghalaya, India

Four species of Lejeunea viz., L. discreta, L. kashyapii, L. mehrana and L. parva are reported here for the first time from Meghalaya. Of which, Lejeunea kashyapii and L. mehrana are endemic, earlier reported from Sikkim only. The taxonomic description and illustrations of all are provided in present communication

Steppe woodlands with Tatarian Maple (Aceri tatarici-Quercetum pubescentis-roboris) on the great Hungarian plain and its neighbourhood. An unfinished synthesis with supplementary notes

This paper presents the so far only partially published research material of the late Bálint Zólyomi on one of his major fields of interest, the forest steppe vegetation. The phytosociological tables presented here were found in his bequest indicating that he was going to publish a grand synthesis on this topic, which, however, has not come true. Since no written text accompanied the original tables, a historical overview and a short explanation to the tables are also provided
