Do ploidy level, morphology, habitat and genetic relationships in Alpine Vaccinium uliginosum allow for the discrimination of two entities?
Evolutionary processes such as recurrent origin of polyploids and enhanced gene flow among polyploids make polyploid complexes taxonomically highly intricate. One such complex is the mostly diploid and tetraploid cloudberries (Vaccinium uliginosum L. s.l.), which are not only one of themost frequent...

Evolutionary processes such as recurrent origin of polyploids and enhanced gene flow among polyploids make polyploid complexes taxonomically highly intricate.

Surprisingly, in spite of its ubiquity there is very little information on variation in ploidy level, habitat and morphology of V. uliginosum s.l. across the Alps and in adjacent areas; also the taxonomic status of V. uliginosum s. str. and V. gaultherioides is controversial.
