Abstract

Allium sect. Codonoprasum represents an evolutionarily young and rapidly radiating group ofbulbous geophytes, with a significant proportion of polyploids and minor morphological differencesbetween species. In the last 20 years, dozens of new species have been described from the Mediterranean.However, very little new information has been obtained on most of them since their description, especiallyin terms of cytogenetic, molecular and distribution data. Allium goumenissanum is a recently describedspecies of this section, known only from three nearby localities in northern Greece. During the last 10 years,we collected population samples of an unknown species of this section from the southern Balkans, whichseemed to be representative of A. goumenissanum. A variety of methods (cytogenetic, molecular,morphological and micromorphological) were used to compare the populations of an unknown species withthe morphologically similar species A. goumenissanum and A. stamatiadae. AFLP, ITS sequencing andgenome size analyses showed that all populations of the unknown species were in fact A. goumenissanumdistinct from A. stamatiadae. The characterization of the morphology and reproduction of A.goumenissanum is completed, and micromorphological and anatomical characteristics of the leaves of bothspecies are newly published. The distribution of A. goumenissanum, based on new data, now includes amore extensive area of north central Greece, and the species is found as a new taxon for Bulgaria.

Abstract

The Poláchovy Stráně -Výří Skály Natural Monument is a well-known but insuffi ciently explored locality of calciphilous and thermophilous fl ora in the submontane landscape of northern Moravia. A total of 305 vascular plant taxa were found during the botanical survey, out of which 20 are included in the national red list of endangered species. The occurrence of Cypripedium calceolus, Gentiana cruciata, Moneses unifl ora and Neotinea ustulata is of particular importance. From a phytogeographical point of view, the area is noteworthy for co-occurrence of some thermophilous and montane species, both growing here on their local elevation limits. Vegetation of the natural monument consists mostly of seminatural or artifi cial woods, with only remnants of valuable beech and hornbeam forests. Even cultivated spruce forest however appeared to be suitable for some endangered species, including several calciphytes. Mesophilous meadows and pastures also signifi cantly contribute to the species richness of the natural monument, which is a result of an ongoing traditional farming. [ABSTRACT FROM AUTHOR]

Abstract

This article summarizes historical and recent records of Field Cudweed in Olomouc. In the urban area, this species is bounded to permanently disturbed habitats, as railways, tram lines and city grasslands. Its populations may be endangered by application of weedkillers or intensive mowing of the grasslands. The most promising populations occur in the botanical garden and in Fort Radikov. New findings of the species in the city may be expected. [ABSTRACT FROM AUTHOR]
