摘要：

An introduction is presented to a taxonomic evaluation of rich cultivated and herbarium material of the genus Taraxacum from the Caucasus. Sources of the material, a survey of localities, and a preliminary account of the sections and species groups of Taraxacum described from the Caucasus are given. The introduction is followed by a monograph of T. sect. Porphyrantha, a section shown (contrary to the original conception and some literature data) to be endemic to the Caucasus. Six new species are described belonging to the section divided in two subsections, subsect. Porphyrantha and subsect. Haemantha, viz. T. pseudoporphyranthum, T. vepallidum, T. haemanthum, T. ignivomum, T. eutinctum and T. deminutum. Lectotypes are selected for T. porphyranthum BOISS. and T. pseudoroseum SISKIN.
