Abstract

Dandelions (Taraxacum) of the section Erythrosperma were studied in Moravia, Czech Republic, where both sexual diploid and apomictic polyploid species occur. Diploid species T. erythrospermum grows in the warmest part of southern Moravia and is confined to natural dry grasslands, whereas some apomictic species have ranges extending up to the submontane regions and prefer ruderal habits. Altogether, 21 apomictic types were found repeatedly but only seven were identified as previously described species: T. arcuatum, T. danubium, T. lacistophylloides, T. parnassicum, T. plumbeum, T. proximum and T. scanicum. Descriptions, notes on variation and distribution in Moravia, dot maps and pictures are given for eight species.
