Saussurea × media (Asteraceae), a new natural hybrid between S. parviflora and S. controversa
Nordic Journal of Botany, Volume 2026, Issue 11, November 2026.Saussurea × media Yusupovsky and E.Pjak (Asteraceae), a new nothospecies from the Altai‐Sayan Mountains, is described and illustrated. In this study, we sequenced the internal transcribed spacer of nuclear ribosomal DNA and the chloroplast intergenic spacers rsp16‐trnQ and ycf4‐cemA to verify the hypothesis of hybridization between Saussurea parviflora

Nordic Journal of Botany, Volume 2026, Issue 11, November 2026.The circumscription of the Paleotropical dioecious and species‐rich genus Timonius Rumph. ex DC. nom. cons.has long been based on a restricted combination of morphological features, namely valvate corolla aestivation and drupes bearing multiple, free, single‐seeded pyrenes. Previous studies, focused on different taxonomic problems in tribe Guettardeae,
