[EN] The genus Rhaponticum in East Asia has always been a taxon for discussion. Rhaponticum carthamoides from East Siberia comprises three subspecies: carthamoides, chamarensis and orientale. Even though they differ in morphology, they do not have isolated areas. Rhaponticum satzyperovii was recently described and its author pointed out its affinity with Rh. uniflorum. Plant height, stem indumentum, and radical and stem leaf dissection were signaled as the diagnostic characters. Our present study on living and herbarium specimens of Rh. satzyperovii shows that the diagnostic characters are not consistent. The species area was also claimed to be an argument for considering Rh. satzyperovii a distinct species. This area covers the south of the Primorye Province in the Far East of Russia with some locations in the adjacent Jewish Autonomous Region and in China. In our study, the area of Rh. satzyperovii is found to be within the area of Rh. uniflorum and thereafter they turned out to have no disjunction. In East Asia, Rh. uniflorum is characterized by a wide range of morphological variability. We suggest that Rh. satzyperovii should be included within Rh. uniflorum without any taxonomic rank.
[ES] discutido. Rhaponticum carthamoides del Este de Siberia incluye tres subespecies: carthamoides, chamarensis y orientale. Aunque difieren en su morfología, sus áreas no están aisladas. Rhaponticum satzyperovii fue descrito recientemente y su autor señaló su afinidad con Rh. uniflorum. Los caracteres diagnósticos fueron la altura de la planta, el indumento del tallo y las divisiones de las hojas basales y caulinares. Nuestro estudio de plantas vivas y muestras de herbario de Rh. satzyperovii muestra que los caracteres diagnósticos no son consistentes. El área de distribución también se argumentó para considerar Rh. satzyperovii una especie diferente. El área cubre el sur de la provincia de Primorye en el extremo Este de Russia con algunas localidades en la adyacente región Autónoma Judía y en China. En nuestro estudio hemos visto que el área de Rh. satzyperovii está dentro del área de Rh. uniflorum y por lo tanto no cabe hablar de disyunción. En el Este de Asia, Rh. uniflorum se caracteriza por un amplio rango de variabilidad morfológica. Proponemos que Rh. satzyperovii se incluya en Rh. uniflorum sin ningún rango taxonómico.
