Callistopteris
''Callistopteris'' is a fern genus in the family Hymenophyllaceae. The genus is accepted in the Pteridophyte Phylogeny Group classification of 2016 (PPG I) but not by some other sources, which sink it into a broadly defined ''Trichomanes''. Taxonomy The genus ''Callistopteris'' was erected by Edwin Copeland in 1938. Its status, like other genera in the family Hymenophyllaceae, remains disputed.

Hymenophyllaceae
The Hymenophyllaceae, the filmy ferns and bristle ferns, are a family of two to nine genera (depending on classification system) and about 650 known species of ferns, with a subcosmopolitan distribution, but generally restricted to very damp places or to locations where they are wetted by spray from waterfalls or springs. A recent fossil find shows that ferns of Hymenophyllaceae have existed since at least the Upper Triassic. Description They often appear as very dark green or even black clumps and may be mistaken for a robust moss or liverwort. The rhizome is usually thin and wiry and the fronds variously pinnate with a single strand ("nerve") of vascular tissue. As in most ferns, young fronds have circinate vernation. In most species, the frond, apart from the vascular tissue, is only a single cell thick, and they do not have any stomata. The cuticle is also greatly reduced or absent, leaving filmy ferns very susceptible to desiccation where a reliable water supply is not ...

Callistopteris Baueriana
''Callistopteris bauerianum'', known as the large filmy fern and Bauer's bristle fern, is a fern in the family Hymenophyllaceae. The specific epithet honours the Austrian botanical artist, Frederick Lucas Bauer (1760–1826), who collected plants on Norfolk Island in 1804–1805. Description The plant is a terrestrial or lithophytic fern. It has a short, erect rhizome, supported by coarse roots, with dark brown, filiform scales. Its tripinnate fronds combine a 5–25 cm tall stipe with a lanceolate lamina 10–30 cm long. Distribution and habitat The fern is endemic to Australia's subtropical Lord Howe and Norfolk Islands in the Tasman Sea The Tasman Sea (Māori: ''Te Tai-o-Rēhua'', ) is a marginal sea of the South Pacific Ocean, situated between Australia and New Zealand. It measures about across and about from north to south. The sea was named after the Dutch explorer Abe ...; it grows in deep shade beside forest streams. References Hymenophyllales ...

Trichomanes
''Trichomanes'' is a genus of ferns in the family Hymenophyllaceae, termed bristle ferns. The circumscription of the genus is disputed. All ferns in the genus are filmy ferns, with leaf tissue typically 2 cells thick. This thinness generally necessitates a permanently humid habitat, and makes the fronds somewhat translucent. Because of this membrane-like frond tissue, the plant is prone to drying out. “Filmy ferns” in the taxa Hymenophyllaceae grow in constantly wet environments. Many are found in cloud forests such as “Choco” in Colombia. There are also members of the taxa that can grow submersed in water. The name bristle fern refers to the small bristle that protrudes from the indusia of these ferns. Taxonomy The genus ''Trichomanes'' was first described by Carl Linnaeus in 1753. Its status, like other genera in the subfamily Trichomanoideae, remains disputed. The Pteridophyte Phylogeny Group classification of 2016 (PPG I) accepts the genus as one of eight in the sub ...

Pteridophyte Phylogeny Group
The Pteridophyte Phylogeny Group, or PPG, is an informal international group of systematic botanists who collaborate to establish a consensus on the classification of pteridophytes (lycophytes and ferns) that reflects knowledge about plant relationships discovered through phylogenetic studies. In 2016, the group published a classification for extant pteridophytes, termed "PPG I". The paper had 94 authors (26 principal and 68 additional). PPG I A first classification, PPG I, was produced in 2016, covering only extant (living) pteridophytes. The classification was rank-based, using the ranks of class, subclass, order, suborder, family, subfamily and genus. Phylogeny The classification was based on a consensus phylogeny, shown below to the level of order. The very large order Polypodiales was divided into two suborders, as well as families not placed in a suborder: Classification to subfamily level To the level of subfamily, the PPG I classification is as follows. *Class Lycopodi ...

Edwin Copeland
Edwin Bingham Copeland (September 30, 1873 – March 16, 1964) was an American botanist and agriculturist. He is known for founding the University of the Philippines College of Agriculture at Los Baños, Laguna and for being one of the America's leading pteridologists (one who studies ferns). Life In 1903, he and his family moved to the Philippines, where he worked as a Systematic Botanist for the Bureau of Science. Wagner, W.H. Jr. 1964Edwin Bingham Copeland (1873–1964) and his contributions to Pteridology American Fern Journal 54(4): 177–188. In 1909, he founded the University of the Philippines College of Agriculture at Los Baños, Laguna, now part of the University of the Philippines Los Baños, and served as its dean and also as a professor of plant physiology for eight years (1909–1917). In 1917, he returned to the United States and was a leading rice grower in Chico, California. In 1927, he began work as an Associate Curator at the University of California, Berk ...
