Opis:
Although intraspecies researches within the black pine (Pinus nigra Arnold) have a long tradition, the intraspecies taxonomy, classification and chorology are still unclear. Among the numerous reasons that have caused this situation the most important are: the absence of a study that would completely cover the whole range of this species, the impossibility of connection of results of the existing detailed studies of certain areas, and the high variability of traits which have been used so far. Since the characteristics of the molecular systematic techniques could make possible the research free of the mentioned shortages, the intention of this study was to determine the relationships among nine populations of black pine using the random amplified polymorphic DNA (RAPD). The obtained results were compared to the recent results of the morphological and anatomical analysis of the leaves of the same populations. The RAPD results clearly divided the Croatian populations from populations of Austria (subsp. nigra) and Turkey (subsp. pallasiana), while among Croatian populations, as in previous study, the existence of several groups (subsp. illyrica, subsp. dalmatica and transitional population between them) was noticed. It is assumed that the optimisations conducted in this study will finally make possible estimating the relationships on the level of the whole range of the black pine and the classification based on molecular traits that are probably less dependent on environmental influences than it has been the case with the characteristics mostly used so far.

Information on Potamogeton hybrids, their identification, taxonomy, ecology and distribution has not been sufficiently recognised yet. Based on characters of P. x salicifolius (= P. perfoliatus x P. lucens) from a new locality in Poland - the Gatno lake (the Kaszuby Lakeland in NW Poland) - general comments on Potamogeton hybrids identification are introduced. The description of P. x salicifolius morphology from the Gatno lake are presented. Analysis of quantitative morphological characters of these specimens provided new information on variability of this taxon. The distribution map of P. x salicifolius in Poland, the original draft of P. x salicifolius based on specimens from the Gatno lake and the table with comparison of P. x salicifolius and the characters of parental species are also provided.

Opis:
The leaf epidermis of 36 taxa (species, subspecies, varieties and cultivars) of the genus Ficus (subgenera Ficus, Synoecia, Sycomorus, Pharmacosycea and Urostigma) was observed under LM and SEM. Characteristics of the epidermis are of particular taxonomic as well as phylogenetic interest because they differ conspicuously between species. The differences are especially prominent in the size and shape of epidermal cells, the shape of cell walls, peristomatal cuticular rim, the distribution and position of stomata, lithocysts, hydathodes, trichomes, and the types of wax, cuticle and trichomes. Results of this study provided data on new qualitative and quantitative traits of the leaf epidermis in the selected taxa, and confirmed the classification suggested by Berg (1989).

Opis:
The location of stomata and the structural details of exostome teeth and endostome segments are among the most important taxonomic features used for identifying Orthotrichum species. Certain species pairs (e.g. O. stramineum vs. O. pallens; O. pumilum vs. O. stellatum) are distinguished based on the presence or absence of hair on the vaginula. The authors have shown that this feature is not always appropriate for species identification. Some specimens of O. affine, O. anomalum or O. speciosum were found to have a hairy vaginula, although this feature is not included in their description. The confusion with species determination was resolved in a subsequent DNA analysis of the specimens. The reliability of this character is briefly discussed in the paper.

Opis:
Pollen grain of 16 species and three hybrids of the genus Amygdalus L., representing two subgenera and two sections distributed in Iran were examined by light and scanning electron microscopy. All pollen grains are tricolporate. The shape of grains varies from subprolate through prolate. Regarding outline, in polar view, pollen grains are triangular-circular and in equatorial view, elliptic. Regarding sculpturing of exine, the frequent type like many members of family Rosaceae is striate with or without perforations that can be subdivided into three subtypes: type I (A-B), type II (A-B) and type V. In three species, A. trichamygdalus, A. spinosissima and A. orientalis, exine sculpture type is completely different. In the first species is rugulate, in the second species is reticulate and in A. orientalis, it is gemmate-perforate. Ornamentation of ridges (muri) in the striate sculpture is parallel to ectocolpus. Number of perforations in tectum, diameter of them, striae intervals and the thickness of ridges varies among studied taxa. The striae have different depth and slope. Results showed that among pollen grain characters, shape is useful character solely for separating of taxonomic ranks in Iranian Amygdalus specially in subgeneric or section level.

Opis:
Hormotila ramosissima Korš., a very rare in the world and poorly known species, have been found in peat bogs of Lower Silesia. The growth stages typical of this species but unknown so far, have been described and illustrated. It was found that this species has many features in common with the representatives of Volvocales, Tetrasporales, and chlorococcales. The regularly observed zoospores and hemizoospores, which accompanied the various developmental stages of that species, showed an internal structure of Chlamydomonas-type. Studies on Hormotila ramosissima were based on live material collected in ample quantities from peat bogs. The collected in this way repeatable and abundant data allowed to discuss problems concerning morphology, reproduction and development, as well as consider the taxonomic position this species.

Browne (Cladoniaceae) carried out by the author in the region of Spitsbergen in 2002 as well as taxonomical work and revision of herbarium material, collected during several earlier Polish polar expeditions to this part of the Arctic. As the result not reported so far from the island species Cladonia stygia (Fr.) Ruoss, C. trassii Ahti, C. verticillata (Hoffm.) Schaer. have been determined. Besides, the presence of very rarely recorded taxa C. crispata var. cetrariiformis (Delise) Vain., C. merochlorophaea Asahina and Cladonia symphycarpia (Flörke) Fr. is confirmed and their new localities are given. Furthermore, the presence of C. coccifera s.str. is also substantiated.

Opis:
This paper presents the results of a floristic study focusing on taxa representing the genus Gomphonema in Kobylanka stream, situated ca 30 km NW of Kraków. Species belonging to the genus Gomphonema Ehr. were very frequently observed diatom taxa in the material studied. Amongst 272 diatom taxa recorded in the studied material, 13 belong to this genus. Some of them are widespread and often found in Poland; others such as Gomphonema micropus Kutz. and G. sarcophagus Greg. are rarely or for the first time reported from the Kraków-Częstochowa Upland. G. brebissonii Reichardt, G. lagerheimii A. Cl. and G. parallelistriatum Lange-Bert. and Reichardt are new to the Polish flora. Identification of the diatom flora was based on light (LM) and scanning electron microscopy (SEM). Morphological characters and dimensions of frustules were measured for all taxa reported. Ecological requirements, remarks on distribution, and photographic documentation are also given.
