Notholaena Bryopoda
''Notholaena'' (from Ancient Greek νόθο(ς) + χλαῖνα), cloak fern, is a genus of ferns in the Cheilanthoideae subfamily of the Pteridaceae. Ferns of this genus are mostly epipetric (growing on rock) or occurring in coarse, gravelly soils, and are most abundant and diverse in the mountain ranges of warm arid or semiarid regions. They typically have a creeping or erect rhizome and leaves that are pinnatifid to pinnate-pinnatifid with marginal sori protected by a false indusium formed from the reflexed margin of the leaf. Members of ''Notholaena'' also have a coating of whitish or yellowish farina (a powdery secretion that prevents desiccation) on the surfaces of the leaves. The farina is often limited to the abaxial (lower) leaf surface, but may occur on the adaxial (upper) leaf surface as well. Members of the related Pentagramma genus have a similar lower leaf-surface farina. The similar genus ''Argyrochosma'' also has farinose leaves, but in that genus the ult ...

Robert Brown (botanist, Born 1773)
Robert Brown (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders. Early life Robert Brown was born in Montrose on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown, a minister in the ...

Cheilanthes
''Cheilanthes'', commonly known as lip ferns, is a genus of about 180 species of rock-dwelling ferns with a cosmopolitan distribution in warm, dry, rocky regions, often growing in small crevices high up on cliffs. Most are small, sturdy and evergreen. The leaves, often densely covered in trichomes, spring directly from the rootstocks. Many of them are desert ferns, curling up during dry times and reviving with the coming of moisture. At the ends of veins sporangia, or spore-bearing structures, are protected by leaf margins, which curl over them. Taxonomy The genus name is derived from the Greek words χεῖλος (''cheilos''), meaning "lip," and ἄνθος (''anthos''), meaning "flower." ''Cheilanthes'' as traditionally circumscribed is now known to be highly paraphyletic, comprising at least four generically separate groups. The type species, '' C. micropteris'', is most closely allied to the genera ''Aleuritopteris'' and '' Sinopteris'' (Schuettpelz ''et al.''). In the ...

Notholaena Cubensis
''Notholaena'' (from Ancient Greek νόθο(ς) + χλαῖνα), cloak fern, is a genus of ferns in the Cheilanthoideae subfamily of the Pteridaceae. Ferns of this genus are mostly epipetric (growing on rock) or occurring in coarse, gravelly soils, and are most abundant and diverse in the mountain ranges of warm arid or semiarid regions. They typically have a creeping or erect rhizome and leaves that are pinnatifid to pinnate-pinnatifid with marginal sori protected by a false indusium formed from the reflexed margin of the leaf. Members of ''Notholaena'' also have a coating of whitish or yellowish farina (a powdery secretion that prevents desiccation) on the surfaces of the leaves. The farina is often limited to the abaxial (lower) leaf surface, but may occur on the adaxial (upper) leaf surface as well. Members of the related Pentagramma genus have a similar lower leaf-surface farina. The similar genus ''Argyrochosma'' also has farinose leaves, but in that genus the ult ...

Notholaena Californica
''Notholaena californica'' is a species of fern known by the common name California cloak fern. It is native to southern California and Arizona in the United States, and in adjacent north-western Mexico, where it grows in dry and rocky conditions, often in desert and chaparral habitats. Description The leaves are divided into often asymmetrical leaflets which are subdivided into lobed segments, the leaf measuring 3 to 20 centimeters in total length, not counting the long, brown petiole. It is hairless and lacks scales. The leaf is covered in grainy exudate known as farina. As with many other Cheilanthoid ferns, the fronds can curl up when dry and expand again with moisture. ;Chemotypes The fern comes in two chemotypes which can be distinguished by the color of the farina, white or yellow, and the two are rarely found growing together. The two chemotypes are sometimes treated as subspecies. Subspecies *''Notholaena californica'' ssp. ''californica' '— Transverse Ranges, Penin ...
