Recent changes in sylvicultural practices in Central Europe have created forests with closed canopies, and tree species preferring open and sunny forests have declined in area and abundance. This led to increased isolation of populations of many rare insect-pollinated, fleshy-fruited species with a naturally scattered distribution. To gain insight into the regional population dynamics of such s...

Sorbus torminalis (WILD SERVICE TREE) is described and illustrated. It a species relatively isolated from its relatives, but role as parental taxon of hybridogenic noted. Notes on usage, cultivation propagation are included.

Abstract Triassic limestone areas of Thuringia are well-known for their richness hybrids between S. aria and torminalis (subgenus Tormaria ). Those have been originally described as endemic taxa (i.e. Sorbus heilingensis, isenacensis However, the former endemics recently synonymized with S . × decipiens ( Karpatiosorbus hybrida (Bechst.) Sennikov & Kurtto) due to diploidy putative sexuality...

Rowan species (genus Sorbus L., Rosaceae Juss.) are widespread in the Northern Hemisphere under different climatic and ecological conditions. Recent molecular-phylogenetic studies confirmed that genus L. is polyphyletic must be divided into segregate genera. Accordingly, native for Ukrainian flora domestica torminalis (L.) Crantz., having very distant morphological features of vegetative genera...
