Diplazium
''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 modified ...

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 ...

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] |
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.

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. The sori are up to a centimeter long and are narrow and somewhat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Athyriaceae
The Athyriaceae (ladyferns and allies) are a family of terrestrial 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 Athyrioideae of a very broadly defined family Aspleniaceae. The family has with a cosmopolitan distribution. Description Species of the Athyriaceae are terrestrial or lithophytic, less commonly aquatic. They grow from various kinds of rhizome: short or long, creeping or erect, branched or not. The distribution and evolution of characters in the family is complex, and the genera have few constant features by which they can be identified. The sporangia have stalks two or three cells wide in the middle, and contain brown monolete spores. Taxonomy Earlier classifications The family was first created by Arthur H.G. Alston in 1956. It has had a varied history. In 2014, Christenhusz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Storage Organ
A storage organ is a part of a plant specifically modified for storage of energy (generally in the form of carbohydrates) or water. Storage organs often grow underground, where they are better protected from attack by herbivores. Plants that have an underground storage organ are called geophytes in the Raunkiær plant life-form classification system.; reprinted (1977) in ''History of ecology'' series, New York: Arno Press, Storage organs often, but not always, act as perennating organs which enable plants to survive adverse conditions (such as cold, excessive heat, lack of light or drought). Relationship to perennating organ Storage organs may act as perennating organs ('perennating' as in perennial, meaning "through the year", used in the sense of continuing beyond the year and in due course lasting for multiple years). These are used by plants to survive adverse periods in the plant's life-cycle (e.g. caused by cold, excessive heat, lack of light or drought). During these pe ...

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] |
