Two computer data bases were formed: reference base «Prodromus» including the nomenclature forest syntaxa and experienced geobotanic releves «Forests of European Russia». Ecological, coenotic and floristic analysis of broadleaved-coniferous forests mostly corresponding to association Rhodobryo rosei – Piceetum abietis Korotkov 1986 was conducted with these bases. Releves (305) from South taiga and broadleaved-coniferous subzone were used. The analysis revealed complex syntaxonomy, bo­real-nemoral character and wide distribution ass. Rhodobryo-Piceetum from central European Russia. Ecolo­gical comparison of this association with some no­men­clature types of broadleaved-coniferous communities in East Europe was carried out. Preliminary prodromus for Euro­pean Russian mixed forests is suggested. Role of ecologi­cal, succession and regional factors was shown for dif­ferentiation of syntaxa.

A New Species

Treinta estaciones en el Parque Nacional El Kala (Noreste de Argelia) fueron objeto de un inventario florístico que se centró en el estudio de la ecología de geófitos bulbosos y tuberosos. La flora se caracteriza por una alta proporción de taxones raros y/o endémicos, entre ellos, 6 especies son endemismos algero-tunecinos pertenecientes a la familia Orchidaceae. En este trabajo, se da a conocer la presencia de una nueva especie para la flora argelina, Ophrys fusca subsp. lupercalis. Los análisis multivariantes revelaron, ciertas variables ambientales que determinan la distribución de los geófitos. Los lugares de interés son particularmente sensibles a las amenazas, particularmente las de origen antrópico. Thirty stations at the El Kala National Park (North Eastern Algeria) were the subject of a floristic focused on the study of the ecology of bulbous and tuberous geophytes. The floristic analysis was used to draw up a checklist of 67 species belonging to 36 genera and 14 families, among of which 19 species a high proportion of rare and/or endemic taxa; among them six signed taxa are endemic to algerian-tunisian mainly represented by family of Orchidaceae. In this work, we recorded the presence of a new species for the Algerian flora which is Ophrys fusca subsp. lupercalis. Multivariate analyses revealed certain environmental variables determining the distribution of geophytes. The visited sites show an alarming vulnerability and subject to threats, particularly anthropogenic ones.

The study area comprises two mountain groups – Wielka Racza and Pilsko – situated in western part of the Beskid Żywiecko-Orawski Range in Polish Western Carpathians. The flora of this area includes 111 species of liverworts and 2 species of hornworts. 81 species of liverworts and 2 species of hornworts were found in the area of the Wielka Racza group, 108 species of liverworts and 2 species of hornworts – in the area of the Pilsko group. The species new for the Polish part of the Beskid Żywiecki Range were found (27), as well as for the whole Range including the Slovakian part (22) and for the Western Beskids (2). Moreover, 20 species rare in the Western Beskids as well as 11 species rare in the whole area of the Western Carpathians were recorded. 6 species regarded as threatened in the Polish flora occur in the study area. Four of them belong to the category of endangered species (E):<em> Fossombronia wondraczekii, Frullania tamarisci, Porella baueri</em> and <em>P. platyphylla</em>, the remaining two belong to the category of vulnerable species (V): <em>Geocalyx graveolens</em> and <em>Metzgeria conjugata</em>. A particular attention should be payed to the species threatened on European scale: <em>Lophozia ascendens</em> (R category), <em>Porella baueri</em> (T) and <em>Scapania parvifolia</em> (T). The floristic analysis of habitats covered by liverworts as well as habitat groups of liverworts and habitat preferences of particular species arę presented in the paper. The phytogeographic characteristics of the flora is also given, including vertical and horizontal distribution of liverworts in the study area.

Abstract The floristic investigation of the Ionian island of Kalamos resulted in the addition of 275 specific and infraspecific taxa, which are reported here, to a present total of 502 taxa. For each newly recorded taxon local distribution and habitat types are presented. Convolvulus pentapetaloides and Malcolmia graeca subsp. hydraea are reported for the first time from the Ionian islands. Some of the new records concern rare taxa in Greece or regional endemics, which are, therefore, chorologically significant, such as Alkanna corcyrensis, Stachys ionica, Heptaptera colladonioides. A brief description of some of the vegetation types of the island is given. The results of floristic analysis and phytogeographical aspects demonstrate the pronounced Mediterranean character of the island’s flora.

The charophytes (Charales, Charophyta) from south-eastern South Australia and south-western Victoria were studied on the basis of collections from 56 waterbodies, 39 of which included charophytes. Chara globularis var. globularis (Thuillier) Wood, C. globularis var. virgata (KÜtzing) Wood, C. fibrosa var. fibrosa (Agardh ex Bruzelius) Wood, C. fibrosa var. acanthopitys (Braun) Wood, C. hookeri Braun, C. preissii (Braun) Wood, Lamprothamnium macropogon (Braun) Ophel, Nitella ignescens García, N. ungula García, N. lhotzkyi (Braun) Braun, N. aff. lhotzkyi, and N. congesta (Brown) Braun were recognised. An identification key for these species makes determination possible. A brief characterisation of the environment where the charophytes were found is provided, as a first approximation of the ecological requirements of Australian charophytes. At this stage their distribution can be mainly related to salinity, with charophytes living in fresh to hypersaline conditions (0.0–58.0 g L–1). Special attention is put on L. macropogon, a euryhaline calcifying species, which has the broadest distribution in the area. The floristic analysis shows endemism, dioecism and a high diversification of non-calcifying taxa as the main characteristics of the charophyte flora analysed.
