Historia terenu Arboretum Bramy Morawskiej [History of the area of the Moravian Gate Arboretum]
Paweł Kojs, Waldemar Szendera, Wiesław Włoch
The Arboretum of Brama Morawska in Racibórz was founded on the 1st May 2000 on the base of municipal forest “Obora” in result of the cooperation between Town Racibórz and the Department for Conservation of Biodiversity of the Upper Silesia (Botanical Garden – Centre for Biological Diversity Conservation of the Polish Academy of Sciences). Natural value of Arboretum is associated with the forest communities, which persisted due to the extensive forest management (the lack of clear cuttings and protection of natural stand). Rich biodiversity of Arboretum is also associated with the close vicinity of Brama Morawska, which is a natural path of migration of plant and animal species. Biodiversity of Arboretum is influenced by local, mild microclimate. Due to its great natural values forest “Obora” has been included within Landscape Park “Cysterskie kompozycje krajobrazowe Rud Wielkich” since 1992. The area of Arboretum is also an element of ecological corridor of Upper Odra, with international significance.

Naturalne zbiorowiska leśne Arboretum Bramy Morawskiej [Natural forest communities in the Moravian Gate Arboretum]
Jan Duda, Aleksandra Rusin, Paweł Kojs, Wiesław Włoch
The Arboretum of Brama Morawska was founded on the base of the Municipal Forest “Obora”, which was never in its history deforestated or strongly deformed by the intensive forest management. For these reasons natural forest communities are well preserved. The largest area is covered by the oak-hornbeam forest (Pol. = grąd), which deserves special conservation in the plain Plaskowyż Rybnicki. In the area of Arboretum two types of the oak-hornbeam forest can be distinguished: the low oak-hornbeam and high oak-hornbeam forest. Undergrowth of the oak-hornbeam forest is characterized by the high ratio of covering and abundance of species. On the small area (3% of the area of the Arboretum, on the muddy, marshland soil, with the high level of ground water, there is formed the community of the riverside forest, with alder and ash, Circaeo-Alnetum. On similarly small area, with stagnating waters, the alder carrs are formed. Forest communities in the central part of Arboretum are typical for mixed forest.

Flora naczyniowa na terenie Śląskiego Ogrodu Botanicznego (w budowie) w Mikotowie-Mokrem [Vascular flora in the area of the Silesian Botanical Garden (under construction) in Mikołów-Mokre]
Mirosława Berger
The flora of the area of the Silesian Botanical Garden in Mikołów-Mokre comprises more then 650 species of vascular plants, among which there are 20 strictly protected species, 7 partially protected species, and 6 species proposed for protection; 7 species are very rare in the area of the Upper Silesia, and 21 are enrolled in the Red List of Vascular Plants of the Upper Silesia. Mentioned above species occur in their natural habitats, so conservation of their habitats requires special care in the area of the Botanical Garden. Special attention should be paid to such very rare species as: Orchis mascula, O. pallens and Gentianella ciliata, which form the community of unestablished syntaxonomical position.

Badania nad rozmieszczeniem i generatywnym rozmnażaniem cieszynianki wiosennej (Hacquetia epipactis (Scop.) DC.) [Studies on distribution and generative propagation of Hacquetia epipactis (Scop.) DC.]
Jan Duda, Jerzy Puchalski, Waldemar Szendera
The stands of Hacquetia epipactis, described in literature of the administrative district Racibórz were critically reviewed. On the four cited stands this plant is extinct; only four stands of this forest geophyte survived. On the right side of the Odra river there are two natural stands of Hacquetia, seriously endangered. For the mentioned reasons the et Torts to work out the method of generative propagation of Hacquetia from seeds and seedlings collected from natural stands were made. As well, the efforts of reinstating the plants cultured ex situ to their natural stands were made. Generative propagation of Hacquetia epipactis ex situ does not narrow down the genetic pool of the local population, and the genetic pool of the whole population of this species, endangered nearby Racibórz.

Historia badań nad Rubus glivicensis (Sprib. ex Sudre) Sprib. na Górnym Śląsku [History of studies on Rubus glivicensis (Sprib. ex Sudre) Sprib. in the Upper Silesia]
Waldemar Szendera, Wiesław Włoch
Individuals of Rubus glivicensis for herbarium were collected during the period 1989-2000. The investigated area was divided into 497 squares, with the side length 5 × 5 km, according to the methodological assumptions of ATPOL program„ The area of investigation was established within the outline of the Upper Silesia, modified in respect to the boundaries proposed by the Department for Cultural Heritage of the Upper Silesia. Within this area there are included 22 mezoregions of central part of Southern Poland, belonging to the historical boundaries of the Upper Silesia. Ten-year research resulted in the approval of the occurrence of R. glivicensis (Sprib. ex Sudre) Sprib. on 253 stands within the investigated area.

Rosa rugosa Thunb. i jej odmiany – cenne róże parkowe w kolekcji Ogrodu Botanicznego – Centrum Zachowania Różnorodności Biologicznej [Rosa rugosa Thunb. and its varietes – appreciated shrub roses in collection from Botanical Garden – Center for Biological Diversity Conservation of the Polish Academy of Sciences]
Marta Joanna Monder
There are 12 varietes of roses which are hybrids of Rosa rugosa Thunb. planted in the roses collection of Botanical Garden – Center for Biological Diversity Conservation of the Polish Academy of Sciences. Like many other varietes of this origin they are very cold hardy, not susceptible to mildew and blackspot, they also don’t require any special soil. On account of high tolerance of urban conditions, little amount of cultivation treatment, attractive, often fragrant flowers and decorative hips, they can be successfully used in urban greenery on exposed places, as shrub and ground cover roses. The arrangement of roses varietes in groups presented in the article should make easier getting to know them better and their selection.

Jacek Marcinkowski, Mirosława Kamińska
The systematics of genus Iris was the subject to many changes and is very complicated till now. Nowadays the genus Iris contains only species with the typical rhizoms. Over 200 species occur on the northern hemisphere. The cultivars of hybrid origin called bearded irises make 90% of irises cultivated in the garden all over the world, about 80% in the case of the collection in our garden. The rest, species and some of their varieties are presented in the table.

Rodzaj Echinodorus Rich. – uwagi do taksonomii gatunków [The genus Echinodorus Rich. – remarks on the taxonomy of species]
Ryszard Kamiński
In 1975 Karel Rataj published results of his investigations on genus Echinodorus; he specified 47 species, 21 varieties and 4 hybrids of burheads. Nearly 20 years later Haynes & Holm-Nielsen revised this genus again, specifying only 25 species and 5 subspecies. They diminished number of taxa by more than 50%, in spite of the fact that 4 new species from natural localities and 6 species of unknown origin (sic!) had been described in the meantime. In the opinion of the Author of the present paper Rataj’s systematic is too broad, on the other hand the new division seems to be too general in some cases. It concerns especially the polymorphous species E. uruguayensis Arechav. and the little burheads previously belonging to the subgenus Helianthium (Engelm.) Fassett, section Tenelli Fassett. The Author’s conclusions are based on results of cultivation of these taxa. Several dozen plant micropopulations of different provenance (plants of Rataj’s collection being dominating group) were cultivated in differentiated conditions in basins and aquaria of the Wrocław University Botanical Garden. Observations on behaviour of cultivated plants and comparison of plants from particular experiments have given a basis for the following conclusions.

Zadania dla polskich ogrodów botanicznych w zakresie ochrony roślin w skali europejskiej zgodnie z Konwencją Berneńską [The tasks for Polish botanical gardens in the areas of plant species protection on European scale according to the Bern Convention]
Jerzy Puchalski, Halina Galera
Bern Convention from 1979 is an important document for the protection of European flora and fauna species. According to revised Appendix I from 1997 500 vascular plant species occurring in European countries should be protected, as well as their natural habitats. In Polish flora 35 vascular plant species are listed in Appendix I of the Bern Convention. Among them 30 were totally protected by law act from 2001 . The majority of Bern Convention species occurring in Poland (28) were described in the last edition of Polish Red Data Book (Kaźmierczakowa, Zarzycki 2001). Also 3 other species could be treated as endangered. The species: Dianthus nitidus, Gladiolus felicis and Najas flexilis became extinct. Marsilea quadrifolia occurs only in botanical garden collection. It is recommended that Polish botanical gardens must put more attention to ex situ conservation of Bern Convention plants. Besides living plant collections also seed banks could be used as supplementary conservation technique.

Halina Galera, Jerzy Puchalski, Wiesław Gawryś
In this paper information about plant species protected according to Bern Convention (European flora endangered species) cultivated ex situ in the Polish botanical garden was given. Among 35 vascular plant species of Polish flora 18 of the them (51%) were collected by 11 botanical garden. Generally plants introduced into botanical gardens originated from their natural localities. In the case of Dianthus nitidus, extinct in Polish localities, plants were obtained from foreign sources. It is necessary to put more efforts for ex situ conservation of the remaining 17 species from Bern Convention Appendix, especially concerning 2 species not protected in Poland by law: Campanula patula subsp. abietina and Myosotis praecox.

The search for plant polyprenols: screening Polish rare and endangered species [Poszukiwanie poliprenoli roślinych: przegląd polskich gatunków rzadkich i zagrożonych]
Urszula A. Golas, Olga K. Mozgowa, Anna Gasek, Wiesław Gawryś, Roman Muranyi, Ewa Swiezewska, Tadeusz Chojnacki
The long chain polyprenols were shown to be rather uncommon constituents in leaves of several herbaceous plants and of shrubs and trees classified as rare and endangered species. From among the over 100 studied species of vascular plants representing over 50 systematic families in only few of them the accumulation of long chain polyprenols was observed. The types of accumulated polyprenols mixtures were similar to the mixtures characteristic for members of Rosaceae family or for many gymnosperms (Swiezewska et al., 1994).The accumulation of polyprenols composed of 10,11 and 12 isoprene residues was rare in this group of plants. A new type of polyprenol mixture was found to be characteristic for leaves of some species belonging to Graminae (e.g. Melica ciliata)„ They contain a group of polyprenols composed of 14 and 15 isoprene residues as dominating prenologues and a large number of longer chain molecules composed of several tens of isoprene residues. The polyprenols of Graminae occur in the form of carboxylic esters and account for up to ca. 2% of leaf tissue. The results of this search suggest no correlation between the vulnerability of a species and accumulation of polyprenols.

Ogrody botaniczne Sri Lanki [Botanical Gardens of Sri Lanka]
Krzysztof Świergosz
Sri Lanka is situated close to the south-eastern tip of India and has about 65 000 square kilometres. About 75% of total area are lowlands, mountains covering the,. central part of island. The highest peaks reach 2000-2524 m a.s.l. About 3500 flowering plants grow as native, but many new species have been introduced from China, Malaysia, Africa, Ethiopia, Central and South America by travellers and gardeners who have been changing the native flora of this small country for at least two thousand years.
