| Note | Many Japanese authors believe that Synurus deltoides (Aiton) Nakai (syn. Carduus atriplicifolius Trévisan; Centaurea atriplicifolia (Trévisan) Matsumura; Cirsium atriplicifolium Fischer; Cirsium ficifolium Fischer; Onopordum deltoides Aiton; Rhaponticum atriplicifolium (Trévisan) de Candolle; Serratula atriplicifolia (Trévisan) Bentham & Hooker; Serratula atriplicifolia (Trévisan) Bentham & Hooker var. incisolobata Miyabe & Miyabe; Serratula deltoides (Aiton) Makino; Serratula deltoides (Aiton) Makino var. palmatopinnatifida Makino; Silybum atriplicifolium (Trévisan) Fischer; Stephanocoma atriplicifolia (Trévisan) Turczaninow ex Ledebour; Synurus atriplicifolia (Trévisan) Iljin; Synurus deltoides (Aiton) Nakai var. incisolobatus Kitamura; Synurus palmatopinnatifidus (Makino) Kitamura; Synurus palmatopinnatifidus (Makino) Kitamura var. indivisa Kitamura; Synurus palmatopinnatifidus (Makino) Kitamura var. indivisus Kitamura) occurs in Western Japan, Korea and China, and that Synurus pungens (Franchet & Savatier) Kitamura occurs mainly in Northeastern Japan
and is not a synonym of Synurus deltoides (Aiton) Nakai. However Missouri Botanical Garden's W3TROPICS regards Synurus pungens as a synonym of Synurus deltoides. This issue should be resolved by DNA analysis. |
