Sadleria is a genus of six species of ferns in the family Blechnaceae, all endemic to Hawaii.[1]

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]

Species

As of July 2025, the Checklist of Ferns and Lycophytes of the World accepted the following six species:[3]

  • Sadleria cyatheoides Kaulf. (amaumau fern or rasp fern)
  • Sadleria pallida Hook. & Arn.
  • Sadleria souleyetiana (Gaudich.) Moore
  • Sadleria squarrosa (Gaudich.) T.Moore
  • Sadleria unisora (Baker) Rob.
  • Sadleria wagneriana D.D.Palmer & Flynn

The Halemaʻumaʻu crater on Kīlauea is named after S. cyatheoides.
