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 l ...

Diplazium Australe
''Diplazium australe'', commonly known as the Austral lady fern, is a small fern occurring in eastern Australia, New Zealand and Norfolk Island. The habitat is moist shaded areas, often occurring in rainforest Rainforests are forests characterized by a closed and continuous tree Canopy (biology), canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforests can be generally classified as tropi .... 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 Wet ...

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] |

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 a cosmopolitan distribution. Description Species of the Athyriaceae are terrestrial or lithophyte, 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 Phenotypic trait, 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 Spore#Anatomy, monolete spores.

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 of ... [...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 p ...

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 rathe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pteridophyte Phylogeny Group
The Pteridophyte Phylogeny Group (PPG) is an informal international group of systematic botanists who collaborate to establish 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). The classification was presented as a consensus classification supported by the community of fern taxonomists. Alternative classifications of ferns exist and are preferred by some. 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 subord ...

Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...
