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

Contents

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 that studied European ferns. [2]

Species

As of December 2019, the Checklist of Ferns and Lycophytes of the World accepted the following species: [3]

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

<i>Phegopteris</i> Genus of ferns

Phegopteris is a genus of ferns in the family Thelypteridaceae, subfamily Phegopteridoideae, in the Pteridophyte Phylogeny Group classification of 2016. They are known collectively as the beech ferns. Species are native to Asia, North America and Europe.

<i>Lycopodium</i> Genus of vascular plants in the family Lycopodiaceae

Lycopodium is a genus of clubmosses, also known as ground pines or creeping cedars, in the family Lycopodiaceae. Two very different circumscriptions of the genus are in use. In the Pteridophyte Phylogeny Group classification of 2016, Lycopodium is one of nine genera in the subfamily Lycopodioideae, and has from nine to 15 species. In other classifications, the genus is equivalent to the whole of the subfamily, since it includes all of the other genera. More than 40 species are accepted.

<span class="mw-page-title-main">Blechnaceae</span> Family of ferns

Blechnaceae is a family of ferns in the order Polypodiales, with a cosmopolitan distribution. Its status as a family and the number of genera included have both varied considerably. In the Pteridophyte Phylogeny Group classification of 2016, the family has 24 genera, and excludes genera placed in the separate family Onocleaceae. The family is divided into three subfamilies, including Blechnoideae s.s. Alternatively, the entire family may be treated as the subfamily Blechnoideae s.l. of a very broadly defined family Aspleniaceae, and include genera others place in Onocleaceae.

<i>Adenophorus</i> Genus of plants

Adenophorus is a genus of ferns in the family Polypodiaceae, subfamily Grammitidoideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). The genus is endemic to Hawaii.

<i>Woodwardia</i> Genus of ferns

Woodwardia is a genus of ferns in the family Blechnaceae, in the suborder Aspleniineae of the order Polypodiales. Species are known as netted-chain ferns. The genus is native to warm temperate and subtropical regions of the Northern Hemisphere. They are large ferns, with fronds growing to 50–300 cm long depending on the species. The fossil record of the genus extends to the Paleocene.

<i>Blechnum</i> Genus of ferns in the family Blechnaceae

Blechnum, known as hard fern, is a genus of ferns in the family Blechnaceae, subfamily Blechnoideae, according to the Pteridophyte Phylogeny Group classification of 2016. Two very different circumscriptions of the genus are used by different authors. In the PPG I system, based on Gasper et al. (2016), Blechnum is one of 18 genera in the subfamily Blechnoideae, and has about 30 species. Other sources use a very broadly defined Blechnum s.l., including accepting only two other genera in the subfamily. The genus then has about 250 species. In the PPG I circumscription, the genus is mostly neotropical, with a few southern African species.

<i>Sadleria cyatheoides</i> Species of plant

Sadleria cyatheoides, commonly known as amaumau fern or ʻamaʻu, is a fern species in the family Blechnaceae, in the eupolypods II clade of the order Polypodiales, in the class Polypodiopsida. It is endemic to Hawaii and inhabits lava flows, open areas, and wet forests on all major islands up to an altitude of 1,676 m (5,499 ft). Reaching a height of 0.9–1.5 m (3.0–4.9 ft) and a trunk diameter of 7.5–10 cm (3.0–3.9 in), ʻamaʻu resembles a small tree fern. Kīlauea's Halemaʻumaʻu is named for this species.

<i>Doodia</i> Genus of ferns

Doodia is a genus of ferns in the family Blechnaceae, subfamily Blechnoideae, in the suborder Aspleniineae. It is named after Samuel Doody (1656-1706), an English botanist. Distribution of the genus includes parts of Australia and New Zealand.

Georg Friedrich Kaulfuss was a professor at Halle. He described the pteridophytes collected by Adelbert von Chamisso, and he named the fern Cibotium chamissoi after him. The genus Kaulfussia is named for Kaulfuss.
