Diplazium Smithianum
''Diplazium'' is a genus of ferns that specifically includes the approximately 400 known species of twinsorus ferns. The Greek root is ''diplazein'' meaning ''double'': the indusia in this genus lie on both sides of the vein. These ferns were earlier considered part of either the Athyriaceae, Dryopteridaceae, Aspleniaceae, or Polypodiaceae families or recognized as belonging to their own taxonomic family. The Pteridophyte Phylogeny Group classification of 2016 (PPG I) places the genus in the Athyriaceae. The taxonomy of the genus is difficult and poorly known, and by 2009 has never been the subject of a complete monographic study. Their distribution is pantropical, with a few species extending into temperate areas. The rhizome of the genus ''Diplazium'' varies from creeping to erect, and is scaly. Its fronds are deciduous or evergreen, are trophopodicThe trophopod is food storage organ described from a number of North American ferns. It consists of the enlarged and modifi ...

Leaf Shape
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diplazium Molokaiense
''Diplazium molokaiense'' is a rare species of fern known by the common name Molokai twinsorus fern. It is endemic to Hawaii, where it is one of the rarest ferns.Wood, K. R. (2006)Conservation status of the Hawaiian endemic fern ''Diplazium molokaiense'' (Athyriaceae) in Honomanu, East Maui, Hawai'i.''Endangered Species Research'' 5 1-5. It has historically been found on the islands of Kauai, Oahu, Lanai, Molokai, and Maui, but it is thought to have been extirpated from four of them and today can be found only on Maui where fewer than 70 individual plants remain. The fern was federally listed as an endangered species of the United States in 1994. Characteristics This fern has leaves up to about 20 centimeters long growing from a twisted rhizome. Each dark green, shiny leaf is made up of several pairs of leaflets, the largest of which is about 5 × 2 cm. They have pointed tips and slightly rippled edges.

Diplazium Australe
''Diplazium australe'', commonly known as the Austral lady fern, is a small fern occurring in eastern Australia, New Zealand New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island count ... and Norfolk Island. The habitat is moist shaded areas, often occurring in rainforest. Original Diplazium australe is an Australian fern belonging to the thyme family, a distinct genus of the female fern family Athyriaceae, consisting of approximately 350–400 species. According to the research, there are more than 70% and 25% of species in the subtropical and neotropical regions, respectively, while only 5% in Africa. According to the study, the crown group of Diplazium originated in Eurasia and completed the initial diversification in the northern hemisphere. The distribution of Diplazium australe is W ...

Desmophlebium
''Desmophlebium'' is a genus of ferns. In the Pteridophyte Phylogeny Group classification of 2016, it is the only genus in the family Desmophlebiaceae. Other sources place it in a more widely defined Aspleniaceae. Taxonomy The family and genus were erected in 2016, following a molecular phylogenetic study. It was shown that the species previously known as ''Diplazium lechleri'' was sister to a clade formed by the families Hemidictyaceae and Aspleniaceae, considerably removed from the Athyriaceae where it had previously been classified. Accordingly, a new genus and family were created and ''Diplazium lechleri'' transferred to '' Desmophlebium lechleri''. Another species was added to the genus on the basis of its morphology. The generic name refers to the distinctive thickened vein running just inside the edge of a pinna (submarginal) connecting the ends of other veins. The authors derived it from the Greek , , meaning 'band', combined with , , meaning 'vein'. ( is the genitive o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diplaziopsidaceae
Diplaziopsidaceae is a family of ferns in the order Polypodiales. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the family is placed in the suborder Aspleniineae, and includes two genera. Alternatively, it may be treated as the subfamily Diplaziopsidoideae of a very broadly defined family Aspleniaceae. They are described as medium-to-large ferns, which grow near streams in forested areas. Their rhizomes are thick and decumbent to erect. Species are found in east Asia, from China south to New Guinea and east into the Pacific. Taxonomy Maarten J. M. Christenhusz and Xuan-Chun Zhang originally described the family in 2011 by including three genera ''Diplaziopsis'', ''Hemidictyum'', and '' Homalosorus''. Later that year Samuli Lehtonen found ''Hemidictyum'' to be a sister to Aspleniaceae, so ''Hemidictyum'' was placed in its own family, Hemidictyaceae. Christenhusz and Mark W. Chase later included ''Hemidictyum'' in their subfamily Asplenioideae rather ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homalosorus
''Homalosorus'' is a genus of fern with only one species, ''Homalosorus pycnocarpos''. It may also be referred to by its older synonyms ''Athyrium pycnocarpon'' and ''Diplazium pycnocarpon''. Commonly referred to as the narrow-leaved glade fern, narrow-leaved-spleenwort, or glade fern, it is endemic to eastern North America and typically grows in moist woodlands. Once classified in the family Athyriaceae due to its linear, often doubled sori, in the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it is placed in the small family Diplaziopsidaceae, whose other three species are native to east Asia. Other sources place the genus in the subfamily Diplaziopsidoideae of a very broadly defined family Aspleniaceae, equivalent to the suborder Aspleniineae in PPG I. Description ''Homalosorus pycnocarpos'' grows from creeping stems. Its clustered fronds grow to about long and wide. The leaf blade is oblong-lanceolate and once-pinnate. The pinnae are linear and either more-or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polypodiales
The order Polypodiales encompasses the major lineages of polypod ferns, which comprise more than 80% of today's fern species. They are found in many parts of the world including tropical, semitropical and temperate areas. Description Polypodiales are unique in bearing sporangia with a vertical annulus interrupted by the stalk and stomium. These sporangial characters were used by Johann Jakob Bernhardi to define a group of ferns he called the "Cathetogyratae"; the Pteridophyte Phylogeny Group has suggested reviving this name as the informal term cathetogyrates, to replace the ambiguously circumscribed term "polypods" when referring to the Polypodiales. The sporangia are born on stalks 1–3 cells thick and are often long-stalked. (In contrast, the Hymenophyllales have a stalk composed of four rows of cells.) The sporangia do not reach maturity simultaneously. Many groups in the order lack indusia, but when present, they are attached either along the edge of the indusium or in its ...

Eupolypods II
Aspleniineae is a suborder of ferns in the order Polypodiales. It is equivalent to the clade eupolypods II in earlier systems; it is also treated as a single very broadly defined family Aspleniaceae. The suborder generally corresponds with the order Blechnales as described by J. L. Reveal in 1993. Aspleniineae includes some important ferns, including ''Onoclea sensibilis'', the sensitive fern, which grows as a virtual weed throughout much of its temperate North American range, and ferns of the genus ''Thelypteris'', a genus that has shown remarkable speciation. It also includes one of the more common Horticulture, horticultural ferns, ''Matteuccia struthiopteris'', the ostrich fern. Taxonomy In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the group is treated as the suborder Aspleniinae, and divided into 11 families. Alternatively, it may be treated as a single, very broadly Circumscription (taxonomy), circumscribed family Aspleniaceae ''Sensu, sensu lato'', w ...
