Based on herbaria specimens and especially on samples recently collected in the area, a revision of the hornwort genera Dendroceros and Megaceros in the African archipelago of São Tomé e Príncipe is presented. The four resulting species are described and illustrated, with comments on their distribution and ecology. A new species of Dendroceros is proposed, D. paivae C. Garcia, Sérgio et Villarreal sp. nov., which is distinguished by delicate thallus, long and slender capsules, distinct spore ornamentation and a particular epiphyllous ecology, growing closely adherent to living leaves. The new hornwort is rare and localized but abundant where found. Also the presence of Dendroceros crispatus Nees in Africa is confirmed. The genus Megaceros is reported for the first time from São Tomé e Príncipe, corresponding to the second report from Africa of M. flagellaris (Mitt.) Steph. A key to the Dendrocerotaceae from São Tomé e Príncipe is presented.

Nine species of mosses collected from Doi Suthep-Pui National Park are reported new to Thailand. Of these, Rhachithecium is a new generic record for the moss flora of Thailand. Notes on the ecology, morphology, taxonomy, and distribution of new records are included. Fissidens flaccidus Mitt. var. percurrens Wongkuna is described as a new variety from Thailand.

A sterile liverwort inclusion in a piece of Miocene amber from the Dominican Republic is described and assigned to the extant genus Lejeunea. The inclusion resembles a complex of extant American Lejeunea species (L. angusta, L. aphanes, L. cladogyna, L. urbanii) that share autoecy, a small size, and ovate to obovate leaf lobes with rounded apices. A definite assignment to one of these species is impossible due to inacessibility of several diagnostically relevant characters such as perianths and oil bodies. The inclusion is clearly different from the extinct Lejeunea palaeomexicana; hence at least two different Lejeunea species occured in the Miocene of Middle America.

Twelve genera, 37 species, and three varieties of Ptychanthoideae are known in Thailand, including four new records, Archilejeunea kiushiana (Horik.) Verd., Lopholejeunea soae R.-L. Zhu & Gradst., Schiffneriolejeunea polycarpa (Nees) Gradst., and Schiffneriolejeunea tumida var. haskarliana (Gottsche) Gradst. et Terken. Thysananthus aculeatus Herzog is excluded from Thailand. A key, brief descriptions and selected illustrations for the species of Ptychanthoideae of Thailand are provided.

Dicranum viride (Sull. et Lesq.) Lindb. has been found on the southern versant of the Pyrenees (Irati Forest, Navarra). This is the only Iberian locality of this threatened species. In this area the species was only known from Pyrénées-Atlantiques and HauteGaronne in the French versant. Its habitat on the new locality has been studied, comparing to other places in France and Germany where the species is known to occur. In Irati, D. viride prefers the north-facing upper base — lower trunk parts of beech trees, median to large in diameter, and it is usually accompanied by Pterigynandrum filiforme and Hypnum cupressiforme var. cupressiforme. The species is proposed to be included in the Red List of Iberian Bryophytes as “Vulnerable” (VU).

Aneura maxima (Schiffn.) Steph. (Aneuraceae, Marchantiophyta) is reported for the first time from Romania. The specimens were collected from the Lacul Tătarilor Peatbog, near Făgăraş Mountains and lad Valley, Apuseni Mountains. The nearest localities of this species are in the Slovak Republic and Poland. Therefore, this new record shows an expansion of this species' range towards South-East Europe. Habitat preferences and distribution map of the plant in Europe are given.

A scanning electron microscope study of leafy liverworts revealed the presence of surface wax in Lejeunea flava (Lejeuneaceae), Mytilopsis albifrons (Lepidoziaceae), Dinckleria pleurata and D. fruticella (Plagiochilaceae).

During an investigation on the bryophytes of Darjeeling and its neighbouring areas Polytrichastrum formosum (Hedw.) G.L. Smith has been identified from Sandakphu region, which is being reported for the first time from Indian territory. The plants of this species are distinctly characterized by its large, robust size; tomentose stem part below, usually unbranched or bifurcate lower region of stem; lanceolate, serrulate leaves; prominent costa, and numerous lamellae (3–4 cells high, uniform) covering ventral surface in cross section of leaves.
