Opis:
The available phytosociological data and original observations were used for preparing a list of plant communities with Sorbus torminalis on its natural sites in Poland. The community context of its sites showed a wide range: from pine-oak forests (alliance Dicrano-Pinion) and oak forests (Quercetalia robori-petraeae, Quercetalia pubescenti-petraeae) to oak-hornbeam forests (Carpinion) and beech forests (Fagion). Oak-hornbeam forests (Carpinion) are the most frequent communities with S. torminalis in Poland. Despite this, oak forests (especially the open thermophilous forests of Quercetalia pubescenti-petraeae) seem to be the most suitable sites for growth and reproduction of this light-demanding tree species. Some remarks on S. torminalis conservation in the community context were also presented as its passive protection in some forest reserves has proved to be ineffective or even harmful.

Opis:
The paper presents the proposal of a strategy of conservation of genetic resources of wild service tree (Sorbus torminalis) in Polish forests. Some results of the recent studies on distribution, resources and genetic variability of wild service tree in Poland that make a scientific base of the programme are presented. Both in situ and ex situ methods should be applied in conservation of genetic resources of S. torminalis. Conservation affords should first to be focused on forest management oriented in favor of wild service tree (e.g. logging intervention, competition control, preparing of favorable sites for new establishments). Further, in situ measures should include selection of conservation areas (natural gene reserves) and preserving trees of the best quality (protected genotypes). These objects would provide seeds for new establishments and to feed populations of small size. The genotypes of the selected earlier preserving trees (about 250–300) would be protected in ex situ conservation objects – seedling and clonal seed orchards. These plantations would also provide seeds needed for future establishments. The genotypes of endangered populations or single trees of S. torminalis could be preserved in the Forest Gene Bank in Kostrzyca.

Opis:
The results of the study on morphological variation of fruits and seeds of a rare forest tree species Sorbus torminalis (L.) Crantz in Poland are presented and discussed. The ripe fruits were collected from 13 localities widespread within the range of the species. Fruits and seeds were measured according to 13 morphological traits. The biometric data were subjected to multivariate statistical analysis in attempt to define intra and inter populational variation. Most of the fruit and seed traits are significantly correlated and are characterized by moderate level of variation. Traits describing size and shape are higher variable in seeds than in fruits. High level of variation within examined populations was ascertained. The average among population component of variation was only 23.99%. Though the differences between sampled populations are significant, almost no geographical pattern of this differentiation was detected. The biological significance of some of fruit and seed features is discussed in the paper. Examining the collected material a single fruits with 5–6 seeds were found what suggests the presence of three carpels in gynoeceum, a number not previously reported in the species.

Opis:
This paper presents the results of the study on morphological variability of leaves of a scattered tree species Sorbus torminalis (L.) Crantz) in Poland. The leaves from short- and long shoots were collected from 17 localities widespread within the range of the species in Poland. Leaves were measured according to 15 morphological traits. The biometric data were subjected to multivariate statistical analysis in attempt to define variability between local populations. Most of the leaf traits are significantly correlated and are characterised by moderate level of variation. The average among population component of variation was 32.82% and 27.46% for leaves on short- and long shoots, respectively. The differences between sampled populations are significant, but only a weak geographical pattern of this differentiation was detected. Clinal type of variation was ascertained in two traits. Leaf traits which discriminate best the studied populations are also indicated. It was proved that leaves on short shoots differ markedly in shape and size from those of long shoots. Leaves on long shoots are steadier, but morphological trait values are less correlated. The study also confirmed the occurrence of individuals with leaves characteristic for S. torminalis var. perincisa Borbas et Feck and S. torminalis f. mollis Beck in a few Polish populations.

Opis:
A study on achene macro- and micromorphological characters of the following five Polish species of the Senecio jacobaea group was carried out by LM and SEM: S. aquaticus (var. aquaticus and var. barbareifolius), S. erucifolius (subsp. erucifolius and subsp. tenuifolius), S. jacobaea, S. paludosus, and S. subalpinus. The achenes differed in several characters, but the most distinctive differences concerned their indument, especially the length and morphology of hairs. The study clearly shows that two morphologically similar species, S. jacobaea and S. erucifolius, which are often confused can be easily distinguished based on the morphological characters of achenes. Additionally, we showed differences between the achenes of S. erucifolius subsp. erucifolius and subsp. tenuifolius, the two taxa which were not distinguished in floristic studies and herbarium collections from Poland. The key to determine Polish species of the Senecio jacobaea group, based on the morphological characters of achenes, is also given.
Rodzaj Senecio L. (Asteraceae; Senecioneae) jest obszernym i taksonomicznie skomplikowanym taksonem, obejmującym od 1000 do 3000 gatunków, zgrupowanych w około 150 sekcjach. Sekcja Jacobaea, według różnych autorów, obejmuje od trzech do 15 gatunków. Badaniami objęto niełupki pięciu rodzimych dla Polski gatunków rodzaju Senecio, należących do sekcji Jacobaea: S. aquaticus (var. aquaticus i var. barbareifolius), S. erucifolius (subsp. erucifolius i subsp. tenuifolius), S. jacobaea, S. paludosus, S. subalpinus. Do obserwacji cech makro- i mikromorfologicznych niełupek wykorzystano mikroskop świetlny stereoskopowy (LM) oraz skaningowy mikroskop elektronowy (SEM). Obserwowane niełupki różnią się szeregiem cech, jednak najważniejsze różnice dotyczą stopnia owłosienia oraz długości i morfologii włosków. W pracy wskazano cechy pozwalające na odróżnienie dwóch często mylonych gatunków – S. jacobaea i S. erucifolius oraz taksonów wewnątrzgatunkowych w obrębie tego ostatniego. Artykuł zawiera również klucz do oznaczania rodzimych gatunków rodzaju Senecio, należących do sekcji Jacobaea, oparty na cechach niełupek.

The observations included the course of leaf development, leaf coloration and leaf fall as well as flowering, fruit ripening and fall. Sixteen phenophases were taken into account. The differences in timing and duration of S. torminalis phenophases from year to year, between two sites and among trees within the same site are pointed out and discussed.

Trees and shrubs of the Polish part of the Eastern Sudety Mts. The contemporary woody flora of the Polish part of the Eastern Sudety Mts. is comprised of 217 taxa of trees and shrubs, including 153 native and 64 alien species (together with 24 and 5interspecific hybrids respectively). Among them, 31 native species and 48 anthropophytes were recorded for the first time and 5brambles were new for the flora of Poland. 25% of native species were found on many new localities. Only 4 taxa recorded in the literature were not found (Juniperus communis subsp. alpina, Rosa inodora, Rubus bifrons and Sorbus aucuparia subsp. glabrata).

Opis:
Hoary ragwort Senecio erucifolius L. (Asteraceae) is a perennial herb with Eurasiatic distribution. The species occurs rarely in most of Poland, with centre of distribution in its SE part. The paper presents the distribution and conditions of occurrence of Senecio erucifolius in the Western Pomerania (NW Poland) with reference to intraspecific taxa. Eight localities of the species were listed and described: three presently existing localities (four populations), two localities not confirmed at present and three incorrect localities. All presently existing populations of Senecio erucifolius represent subsp. erucifolius. The populations are rather small and they are the components of three plant communities: community with Calamagrostis epigejos, association Arrhenathereteum elatioris and association Tanaceto-Artemisietum. Hoary ragwort should be recognised as an endangered species of the Western Pomerania.
