The present guide to bryologically interesting regions in Germany was prepared for a bryological fieldtrip during the XIV Botanical Congress, Berlin 1987 and deals with the following regions: Fichtel Mountains (Fichtelgebirge), Black Forest (Schwarzwald), the Alps and the Allgäu (Alpen und Allgäu), and the Wettersteingebirge (Bavarian Alps).

The Azores are of bryological interest in many respects: They are young volcanic islands with an age between 4 mio and 40.000 years, are situated in an hyperoceanic environment favouring bryophyte growth, the bryophyte flora is composed of European, Neotropical, African and subantarctic elements, there are about as many bryophyte species as flowering plants, the islands have a comparably high rate of endemic species (on single Azorean islands, all Azorean islands or the Macaronesian islands), and the bryophyte flora gives an impression of the bryophyte flora of continental Europe during Tertiary, since many species such as Echinodium spp. or Andoa berthelotiana, known as fossils from the Tertiary of continental Europe, survived here the glaciation periods and got extinct in Europe.

A guide to bryological hotspots in Europe : [Part 2: The Rur Valley, Eifel Mountains, Germany]
(2005)
The Rur valley is situated in the extreme west of Germany in the western part of the Eifel Mountains, close to the Belgian border. The Rur valley harbours several interesting, mainly bryopyhtes. Most of the interesting species are aquatic species. Very obvious is the oceanic element, which is represented by species such as Platyhypnidium lusitanicum, Hyocomium arnoricum, and Isothecium holtii.

Madeira is bryologically insofar very interesting, as it harbours (like the other Macaronesian Islands) relics of the bryoflora of the Tertiary of continental Europe. Originated in the Tertiary at various times, these volcanic islands were mainly colonized from Europe. Whereas many species got extinct in Europe during the glaciations of the Quaternary, these elements were able to survive in these islands. So we are faced there with an ancient bryoflora, especially in the laurel forests, amongst other phytogeographic elements, mainly mediterranean species.

A list of all liverworts and mosses reported from the Maltese Islands with references has been compiled from the literature, which includes 23 species of liverworts and hornworts as well as 96 taxa of mosses. The list is completed by the results of a bryological fieldtrip in March 2008. During this trip, 14 species of liverworts and 40 species of mosses were collected, of which Cephaloziella baumgartneri, Didymodon luridus, Fissidens gracilifolius, Fossombronia echinata, Funaria pulchella, Riccia cavernosa and Weissia fallax are new to Malta. This raises the number of species known from the Maltese Islands to 23 horn- and liverworts and 100 mosses.

An updated list of the mosses of the Inner Seychelles is given based on the previous literature and collections of the first author in 2008. It includes data on the frequency of species as well as distributional data for the individual islands. The moss flora of the islands is characterized. Campylopus brevirameus Dixon is regarded as synonym of C. julaceus ssp. arbogastii (Renauld & Cardot) J.-P.Frahm. Brachymenium dicranoides, Bryum alpinum, Campylopus flaccidus, C. flexuosus, Ectropothecium brachycladulum, E. chenagonii and E. perrotii are reported as new to the Seychelles. Garckea flexuosa, Syrrhopodon involutus and S. prolifer are reported as new to La Digue, Bryum leptospeiron, Brachymenium exile and Calymperes afzelii as new to Praslin.

Field observations of mixed tufts demonstrate that Hpynum cupressiforme s.str. (excl. imponens, jutlandicum, andoi etc.) consists of several different genotypes which are no modifications. Within a study of herbarium material, the specimens were sorted into different phenotypes, for which names were applied from the literature. Within Hypnum cupressiforme, an expression with straight leaves (var. brevisetum Schimp.) was distinguished as well three with hamate leaves (var. uncinulatum Boul., var. cupressiforme and var. plumosum Mart.), which are differentiated by the size, number and form of alar cells and serrate viz. entire leaf tips. Var. subjulaceum is tentatively regarded as alpine variety of Hypnum lacunosum, var, filiforme is regarded as modification based on the oberservation of transitions.

Contribution to the bryophyte flora of India: the Aralam
Wildlife Sanctuary in the Western Ghats
(2009)
The bryophyte flora of the Aralam Wildlife Sanctuary in the Western Ghats of India is catalogued for the first time. The catalogue consists of 116 taxa (89 mosses, 27 liverworts), of which two are new for India (Plagiochila singularis, Vesicularia dubyana), 21 species are newly reported for Peninsular India (Clastobryopsis planula var. delicata, Barbella chrysonema, Brachymenium leptophyllum, Brachythecium rutabulum, Cololejeunea longifolia, Cyathodium tuberosum, Dicranella amplexans, Didymodon vinealis, Duthiella wallichi, Fabronia assamica, Haplocladium microphyllum, Himantocladium cyclophyllum, Homalia trichomanoides var. trichomanoides, Isopterygium serrulatum, Leskea perstricta, Lopholejeunea kashyapii, Leptotrichella assamica, Macromitrium turgidum, Rhynchostegium hookeri, Splachnobryum assamicum, Thamnobryum siamense) and another 14 species are new for Kerala State (Atrichum pallidum, Chionostomum rostratum, Claopodium prionophyllum, Cololejeunea lanciloba, Cyathophorum adiantum, Dicranella divaricata, Entodontopsis wightii, Fissidens pellucidus, Glossadelphus glossoides, Isopterygium lignicola, Leucodon secundus, Neckeropsis exserta, Plagiochila bischleriana, Timmiella anomala). The species Jungermannia obliquifolia has also been reported as a taxon new to India (Nair et al. in press (a) from this area.

The Moss Flora of Mauritius
(2009)
The mosses reported from Mauritius were compiled from the literature and are listed with localities and references. Included are collections by the first author made in 2007 on the island. Barbula indica, Campylopus flavicoma, Racopilum ayresii and Ectropothecium chenagonii, Groutiella tomentosa, Schlotheimia ferruginosa and Trichostomum crispulum are reported as new to Mauritius. The list includes 238 species. A short survey of the bryological exploration of the island is given.
