Dicksoniaceae
Dicksoniaceae is a group of tropical, subtropical and warm temperate ferns, treated as a family in the Pteridophyte Phylogeny Group classification of 2016 (PPG I), and counting 30-40 species. Alternatively, the family may be sunk into a very broadly defined family Cyatheaceae ''sensu lato'' as the subfamily Dicksonioideae. Most of the genera in the family are terrestrial ferns or have very short trunks compared to tree ferns of the family Cyatheaceae ''sensu stricto''. However, some of the larger species can reach several metres in height. A number of others are epiphytes. They are found mostly in tropical regions in the Southern Hemisphere, as far south as southern New Zealand. Larger tree ferns in the genus '' Cibotium'' were formerly included in Dicksoniaceae, but are now segregated as the family Cibotiaceae. Description Species in the family are generally characterized by large pinnate fronds, 1–4 m long. The family includes several species of tree ferns, which grow a singl ...

Calochlaena
''Calochlaena'' is a genus of ferns within the family Dicksoniaceae. Although these ground ferns resemble bracken, they are only distantly related. Five species are known from Melanesia, Polynesia and eastern Australia. '' Calochlaena dubia'', is a common fern of the east coast of Australia. The name is derived from the Ancient Greek ''kalos'' "beautiful" and ''chlaina'' "cloak", and refers to the soft hairs on the species. The genus was originally described by William Ralph Maxon as a subgenus of the fern genus '' Culcita'', but the differences were such that its members were raised to genus level, and are now considered to be in separate families. ''Culcita'' was restricted to two species, one from Mediterranean Europe and one from North America.

Lophosoria
Lophosoria is a genus of tree ferns within the family Dicksoniaceae. Although it is confined to tropical America in modern times, there is fossil evidence that it was once spread throughout Gondwana with the exception of New Zealand.

''Calochlaena'' is a genus of ferns within the family Dicksoniaceae. Although these ground ferns resemble bracken, they are only distantly related.

Cyatheaceae
The Cyatheaceae are a family of ferns, the scaly tree ferns, one of eight families in the order Cyatheales in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Alternatively, the family may defined much more broadly (Cyatheaceae '' sensu lato'') as the only family in the Cyatheales, with the PPG I family treated as the subfamily Cyatheoideae. The narrower circumscription is used in this article. The family includes the world's tallest tree ferns, which reach heights up to 20 m. They are also very ancient plants, appearing in the fossil record in the late Jurassic, though the modern genera likely appeared in the Cenozoic. Cyatheaceae are the largest family of tree ferns, including about 640 species. Cyatheaceae and Dicksoniaceae, together with Metaxyaceae and Cibotiaceae, do not form a strongly supported monophyletic group and could be paraphyletic, but several individual subgroups are well supported as being monophyletic. Cyatheaceae are leptosporangiate fer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calochlaena Dubia
''Calochlaena dubia'', commonly known as soft bracken, false bracken, common ground fern or rainbow fern, is a small Australian fern in the treefern family Dicksoniaceae. It is very common within its range, and often seen growing under eucalyptus forest, often on the poorer quality soils. It is an easy plant to grow in the garden. Taxonomy One of the many plants described by Scottish botanist Robert Brown in 1810, with the name '' Davallia dubia'', it gained its current name with the new genus ''Calochlaena'' described in 1988. The genus name is derived from the Ancient Greek ''kalos'' "beautiful" and ''chlaina'' "cloak", and refers to the soft hairs on the species, while the species name ''dubia'' is the Latin dubious. It was known for many years as ''Culcita dubia'', before the genus ''Calochlaena'' was split out in 1988. The true brackens belong to the family Dennstaedtiaceae. Description The fronds arise from the thick brown haired rhizomes and are anywhere from 0.4 to 1.5 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coniopteris
''Coniopteris'' is an extinct genus of Mesozoic fern leaves. It was widespread over both hemispheres during the Jurassic and Early Cretaceous, with over 130 species having been described. Most species of ''Coniopteris'' probably had a herbaceous habit. ''Coniopteris laciniata'' had tufts of leaves sprouting from intervals of a thin, creeping rhizome. Coniopteris is ''traditionally'' assumed to have been a member of Dicksoniaceae (which are mostly tree ferns) or a close relative of '' Thyrsopteris.'' However, these affinites have been doubted by a number of authors. A 2020 cladistic analysis found it to be a stem group of Polypodiales, as many ''Coniopteris'' species share with these ferns vertically orientated and an incomplete annulus. However, this feature is not preserved among many ''Coniopteris'' species, and several species from the Northern Hemisphere a complete and obliquely orientated annulus, suggesting a Cyatheales (to which Dicksoniaceae belongs) affinity for at leas ...

Dicksonia
''Dicksonia'' is a genus of tree ferns in the order Cyatheales. It is regarded as related to '' Cyathea'', but is considered to retain more primitive traits, dating back at least to the Jurassic and Cretaceous periods. The fossil record includes stems, pinnules, and spores. The genus contains 20–25 species, distributed from Mexico to Argentina, Brazil, Uruguay and Chile, St. Helena, New Zealand, New Caledonia, Australia, Indonesia, New Guinea, and the Philippines. New Guinea has the greatest diversity, with five species. Species of ''Dicksonia'' found in cultivation include: *''D. antarctica'', soft tree fern *''D. fibrosa'', woolly tree fern *''D. squarrosa'', rough or slender tree fern The genus was first described by Charles Louis L'Héritier de Brutelle in 1788. The name honors James Dickson, a prominent nurseryman and botanist.''Dicksonia antarctica'' – the soft tree fernAustralian National Botanic Gardens 2008 Species Plants of the World Online Plants of the ...
