Staphylea pinnata occurs in Europe, mainly in central and SE areas, and in Asia Minor. In Poland it has a few dozen localities in the Carpathians, plus scattered localities in other regions of southern Poland. The aim of the article was to summarise records on its traditional use in Poland. In some places of its occurrence Staphylea used to be a revered shrub, with many uses. Its hard seeds were used...
In recent years some authors have reported the occurrence of Mahonia aquifolium in Polish forests and started to focus on this species as a potential plant invader in our native plant communities. The authors of this paper have found 5 sites with hybrid Mahonia aquifolium × M. repens. Based on these results we regard successful ornitochory of this species as quite common. It proves a major role of...
Old Common Oaks (Quercus robur L.), often connected with myths and legends, are the largest trees occurring in Central Europe. The present paper describes twelve largest girthed specimens of the species growing in Poland. Authors, based on their own measurements and researches, prepared a ranking list of these unique trees and estimated their health condition. Moreover, their exact localizations in...
Botanic Garden of the Jagiellonian University hosts an old collection of currants and gooseberries. Detailed documentation from the time of Edward Janczewski (1846-1918), who expanded the collection for his work on taxonomy of the genus, is preserved at J. Dyakowska Botanical Museum. It includes list of specimens, maps and microscope slides. Herbarium sheets preserved at the Jagiellonian University...
A new cultivar of maple with very peculiar leaves is described and illustrated. A plant originated spontaneously among the seedlings of Acer platanoides used as rootstocks in an ornamental nursery, Krzywaczka. Probably this type of growth and shape of leaves resulted from gene mutation.
Natural range of the Yellow Azalea Rhododendron luteum Sweet (Azalea pontica L.) includes the Caucasus, Asia Minor, Volhynia and SE rim of the Alps (Slovenia). There is also a natural locality of this species in Poland, in Wola Zarczycka near Leżajsk. The plant was discovered in 1795 in Volhynian Polesia by an eminent gardener Dionizy Mikler, and its popularity grew thanks to the Botanic Garden affiliated...
In 42 rural parks studied in years 1999 and 2000, and subsequently in years 2006 and 2007, 262 taxa and culta of trees and shrubs were recorded. The major constituents of tree stand are native deciduous trees. Rarely encountered are the following taxa: Abies concolor ‘Violacea’, A.procera, Araucaria araucana, Cedrus libani, Chamaecyparis lawsoniana, Ch. nootkatensis, Ch. pisifera, Ginkgo biloba, Juniperus...
The list of 46 self-sowing alien woody plant taxa in Rogów Arboretum is presented, which is an expantion of the list from 1992 when the first article on spontaneous regeneration of alien tree and shrub taxa in the Arboretum was published. Most of species described are rather infrequently found in Polish collections and are known to produce self-seedlings not capable of sexual reproduction, however...
new cultivar of Japanese Cedar is described and illustrated. It originated from seeds received in 1961 from Gadow Arboretum (E Germany) and was propagated by cuttings in 1978 and 1985. The maternal tree in Rogów was killed by frosts during severe winter of 1986/87. The newly described form differs from the type in having very short needles.
For several years, authors of the present paper have been observing specimens of cypresses of the genus Cupressus planted in Szczecin and its vicinity and within the area of the agglomeration of Gdańsk, Gdynia and Sopot as well as in some botanical gardens and arboreta. The work is a collection of materials from long-term observations and a moderately complete study on cypresses grown in the northern...
Presence of plant species, associated with ancient forests (continuous existence >200 years) can be used for assessing woodland biodiversity. The aim of this study is to specify which plant species, included in the ancient forests plant species list, can indicate old woodlands in parks and what plant features are characteristic for certain habitat types. Richest in ancient forest plant species...
The Glinna Dendrological Garden, established in 1880, is situated in north-western part of Poland, in mild climate (USDA Zone 7). In 1938 the collection included 55 species of trees and shrubs, in the post-war period the garden was partially abandoned and neglected, the number of species, often very valuable and big trees, decreased to about 35 taxa. Results of 40-years activity in the garden, under...
The paper describes 11 new woody cultivars selected in Botanical Garden PAS in the years 1977-2009. The new cultivars include: seedlings of Picea pungens found in Podzamcze Nurseries with shoots and needles similar to Picea abies ‘Virgata’; plants selected from seedlings of Carpinus betulus ‘Pendula’ of very variable shapes, from depressed shrubby forms to tall trees with shapely pendant shoots; new...
Polish Dendrology Society was founded in Lvov in 1924 thanks to initiative of Dr. Szymon Wierdak, professor of forestry in the Lvov Technical University. Presidential work of Dr. Wierdak was supported by several friends and colleagues, including some other botanists and dendrologists from Lvov – Stefan Makowiecki, Tadeusz Wilczyński and Antoni Wróblewski. Pre-war activity of the Society was mostly...
There is increasing number of trees dying in large urban agglomerations. The problem is mostly pronounced in the case of street trees. In Polish cities, apart of pollutions generated by traffic, an important factor that causes death of trees is high salt concentration as a result of winter salt application for de-icing of streets. The aim of the study was to assess the growth of limes (Tilia cordata)...
The work analyses the condition of forty nine trees in Świdnica (in the Lower Silesian Voivodship). The listed trees in this town belong to eighteen species, half of which are native and half foreign to our flora. The vast majority are angiosperms. The majority of the listed trees at Świdnica are English Oak (Quercus robur), the rarest examples include Common Ash (Fraxinus excelsior), Silver Maple...
Military archives of the French Army at Vincennes retain many documents of the Napoleonic war. Some of these documents relate to Poland and Lithuania. The military intelligence reports have sometimes been subject to the forests. The article presents the analysis of three of these documents. The two reports on the forests of Lithuania and a forestry part of a report of General Sokolnicki. These documents...
