Taraxacum krasnoborovii Krasnikov (1997: 279)

Kirschner, Jan, Štěpánek, Jan & Buryy, Vladimir V., 2025, Towards a revision of Taraxacum sect. Borealia (Compositae, Crepidinae) in Siberia and the continental Far East, with special reference to the dandelions of the Altai and Kamchatka, Phytotaxa 679 (1), pp. 1-147 : 141

Taraxacum krasnoborovii Krasnikov (1997: 279)

Type:—[ RUSSIA] Prov. Altai, distr. Kosch-Agacz, jugum Czichaczevi, ad fontes affluxionis sinistrae fl. Tekelju ..., 28 Jul 1981, A. Krasnikov & N. Sidorenko ( NS, n. v., currently missing) .

According to the rather laconic description, T. krasnoborovii is characterized by subtubulous florets, blackish, oblong-ovate outer phyllaries with distinct horns (“corniculis falcatis magnis”), presence of pollen, leaves runcinatepinnatipartite, long purplish petioles, and light greyish stramineous, spinulose achenes with a relatively short cone. In the absence of the original material, we conclude that it probably belongs to T. sect. Borealia.

Excluded names

There is a long list of the members of a widely understood section Ceratophora in Tzvelev (1992). The list includes, for instance, members of T. sect. Mongolica ( T. coreanum , T. mongolicum ), several species of T. sect. Stenoloba ( T. multisectum , T. mongoliforme , T. stenolobum , see Kirschner & Štěpánek, 2011b) or a number of members of T. sect. Arctica (see below); other, rather unclear species are also often found among “ Ceratophora ” ( T. heterolepis , T. woroschilovii etc.). We do not treat these records separately, and refer the reader to the new Checklist of Vascular Plants of Asiatic Russia ( Chepinoga et al. 2024), with a revised sectional concept.
