Taxonomy
Georg Friedrich Kaulfuss distinguished the genus in 1824 based on samples of S. cyatheoides acquired by Adelbert von Chamisso in 1821. Chamisso had been serving as the naturalist for a Russian scientific expedition led by Otto von Kotzebue aboard the vessel Rurick.[2] Kaulfuss named the genus after Joseph Sadler (1791–1849), a Hungarian naturalist who studied European ferns.[2]
