The sporophyte of Hymenodon tenellus is newly described. Comparison of types and further specimens allows to clarify the identity in New Caledonia of Bryum daenikeri and Macromitrium serpens and assign them respectively to B. pancheri and M. tongense. Four new species of liverworts: Andrewsianthus chimbuensis, Lejeunea stenodentata, Plagiochila integrilobula and Radula lingulata and new localities of Mitthyridium flavum and Trichosteleum stigmosum are reported.

Based on a recent small bryophyte collection from the western escarpment mountains of Yemen in the vicinity of Ibb (Ibb Governorate), 36 mosses are reported, among them 11 new to the bryoflora of the country. Gemmabryum nanoapiculatum (Ochi & Kürschner) Kürschner comb. nov. is collected for the first time since the type collection. Beside some hygrophytic taxa, growing in the vicinty of water pools and runnels, most of the recorded species belong to drought adapted, xerophytic taxa and fit into the expected bryophyte spectrum for the Arabian Peninsula. Together with pantropical and Afromontane species they indicate a common floral history and past and present migration routes.

Aloina bifrons (De Not.) Delgad. is recorded for the first time in France in the Limagne, Puy-de-Dôme department, Auvergne region. This is a significant northward extension of the species' known range. It grows there on sunny marlaceous lime with gypsum traces on a south-facing steep slope. The French habitat differs significantly from the situation recorded in other parts of the Mediterranean and Irano-Turanic areas, where Aloina bifrons is a typical inhabitant of gypsum soils with a rich assemblage of Xeropottioid elements.

Author citation of four species names in Lembophyllum Lindb. is rectified. Their authorship was incorrectly ascribed to S.O. Lindberg because of the misinterpretation of citations using “ex” and “in”. The following names should correctly be ascribed to E.G. Paris who published them in 1896 in Index bryologicus: Lembophyllum clandestinum (Hook.f. et Wilson) Lindb. ex Paris, L. cochlearifolium (Schwägr.) Lindb. ex Paris, L. divulsum (Hook.f. et Wilson) Lindb. ex Paris and L. vagum (Hornsch. ex Müll.Hal.) Lindb. ex Paris. Lembophyllum sect. Rigodiella (E.B.Bartram) Ochyra et Bednarek-Ochyra, comb. nov. is the correct name for the superfluous sectional name L. sect. Looseria (Thér.) Tangney.

The Mediterranean liverwort flora of the surroundings of Santiago, Central Chile, has been little studied. This paper reports 21 species from the area, including one species new to Central Chile (Cephaloziella divaricata), 9 new to the Metropolitan region (Cephaloziella divaricata, Clevea spathysii, Fossombronia sp., Frullania pluricarinata, Lejeunea globosiflora, Leptoscyphus expansus, Lethocolea radicosa, Riccardia sp., Targionia hypophylla ) and 6 new to Quillota province (Clasmatocolea vermicularis, Clevea spathysii, Gongylanthus dusenii, Lethocolea radicosa, Lunularia cruciata, Symphyogyna circinata). Taxonomic notes are provided on selected species of particular interest. Most of the species grow terrestrially; Frullania pluricarinata and Lejeunea globosiflora occur epiphytic on bark in dry Mediterranean forest. Riccia is the most species-rich genus in the area. Three Riccia species, R. crystallina, R. nigrella and R. trichocarpa, have characteristic disjunct ranges, occurring in Mediterranean and subtropical regions of the northern and southern hemisphere but not in the Tropics. Oil bodies are newly reported for the endemic Gongylanthus dusenii and Lejeunea globosiflora; the latter species is fully described and illustrated for the first time.

A history of the discoveries and descriptions of species of the broadly conceived genus Racomitrium Brid. in the Southern Hemisphere in 1800-1850 is briefly outlined. Dryptodon crispulus Hook.f. et Wilson and D. rupestris Hook.f. et Wilson are the two earliest described species in the Southern Hemisphere, from the Campbell Islands south of New Zealand and Isla Hermite in the Cape Horn area in southern South America, respectively, which are still accepted in modern moss taxonomy. The taxonomic and nomenclatural history of these species is discussed and it is proved that the authorship of their names in Racomitrium should be ascribed to “(Hook.f. et Wilson) Wilson”, not to “(Hook.f. et Wilson) Hook.f. et Wilson”, as commonly used in the bryological literature. The problem of the valid publication of Bucklandiella crispula (Hook.f. et Wilson) Bednarek- Ochyra et Ochyra is briefly considered and Dryptodon rupestris Hook.f. et Wilson is lectotypified.

For the first time, the bryological flora of the Vatican City State has been studied. Research concentrated in particular in the area of the Vatican Gardens, and led to the identification of 121 taxa of bryophytes (14 liverworts and 107 mosses), among which one liverwort and nine moss species are new reports for the Lazio Region. Particularly interesting among these species is the presence of Tortula bolanderi (Lesq. & James) M. Howe, the first report for the Italian peninsula. The study is of considerable floristic and biogeographical importance, and contributes significantly to the knowledge of a territory that until now had been unexplored from the bryological point of view.

Sciuro-hypnum sichuanicum Ignatov & Hedenäs, a rare species previously recorded in China, has been newly reported in the Japanese Alps. A description of the species based on Japanese samples, some ecological and conservational notes, as well as a comparison table among this species and some similar species of the same genus have also been provided.

An annotated check-list of the bryophytes of the Serra de Sintra is presented, based on a compendium of bibliographic records, on the revision of the material stored in Lisbon University herbarium (LISU) and Coimbra University herbarium (COI), as well as on the collections made by the authors during field work in 2011, 2013 and 2014. A total number of 279 taxa were recorded, out of which 5 taxa belong to Anthocerotophyta, 87 to Marchantiophyta and 187 to Bryophyta. Threat status in Portugal for taxa subject to conservation concern is also provided. The dominance of oceanic species on the other chorological types, as well as a remarkably high density of taxa per km² compared to other mountain regions in the Iberian Peninsula, is highlighted.
