Dennstaedtiineae
Dennstaedtiaceae is one of fifteen families in the order Polypodiales, the most derived families within monilophytes (ferns). It comprises 10 genera with ca 240 known species, including one of the world's most abundant ferns, ''Pteridium aquilinum'' (bracken). Members of the order generally have large, highly divided leaves and have either small, round intramarginal sori with cup-shaped indusia (e.g. ''Dennstaedtia'') or linear marginal sori with a false indusium formed from the reflexed leaf margin (e.g. ''Pteridium''). The morphological diversity among members of the order has confused past taxonomy, but recent molecular studies have supported the monophyly of the order and the family.Smith, A. R., K. M. Pryer, et al. (2006). "A classification for extant ferns." Taxon 55(3): 705–731 The reclassification of Dennstaedtiaceae and the rest of the monilophytes was published in 2006, so most of the available literature is not updated.

Polypodiales
The Order (biology), 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 Tropics, tropical, semitropical and Temperate climate, temperate areas. Description Polypodiales are unique in bearing sporangia with a vertical Annulus (botany), 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 Sorus, indusia, but when presen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saccolomataceae
Saccolomataceae is a family of ferns in the order Polypodiales with about 19 species. It has been formerly treated as part of the Dennstaedtiaceae, however it has been classified as its own family according to Smith et al. (2006) The genus ''Saccoloma'' has been classified to include ''Orthiopteris'', but the phylogeny of the group not yet fully understood. The family includes a dozen known species. Description Saccolomataceae generally have the following characteristics: Terrestrial; rhizomes short-creeping to erect and trunk-like; petiole (botany), petioles each with an omega-shaped vascular strand; blades pinnate to decompound and lacking articulate hairs; veins free; sori terminal on the veins; indusium, indusia pouch- or cup-shaped. Taxonomy In 2016 the Pteridophyte Phylogeny Group placed it as the sole family in the Saccolomatineae, one of six suborders making up the Polypodiales order. These suborders are phylogenetically related as shown in this cladogram: Dist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GenBank
The GenBank sequence database is an open access, annotated collection of all publicly available nucleotide sequences and their protein translations. It is produced and maintained by the National Center for Biotechnology Information (NCBI; a part of the National Institutes of Health in the United States) as part of the International Nucleotide Sequence Database Collaboration (INSDC). In October 2024, GenBank contained 34 trillion base pairs from over 4.7 billion nucleotide sequences and more than 580,000 formally described species. The database started in 1982 by Walter Goad and Los Alamos National Laboratory. GenBank has become an important database for research in biological fields and has grown in recent years at an exponential rate by doubling roughly every 18 months. GenBank is built by direct submissions from individual laboratories, as well as from bulk submissions from large-scale sequencing centers.

Hiya (plant)
''Hiya'' is a genus of ferns belonging to the family Dennstaedtiaceae. Described in 2018, it resembles ferns of the genus '' Hypolepis'' but differs from it by multiple characteristics: scrambling, indeterminate and intermittent growth of fronds; stipule-like pinnules at the base of pinnae, and a rachis- costa architecture where the adaxial sulcus of the rachis is continuous with that of the costae and costules. The name of the genus references the name given to imperial guards from the Qing dynasty The Qing dynasty ( ), officially the Great Qing, was a Manchu-led Dynasties of China, imperial dynasty of China and an early modern empire in East Asia. The last imperial dynasty in Chinese history, the Qing dynasty was preceded by the ... of China, ''hiya'', due to the prickly or very rough armed stipes present in the ferns.

Pteridium
Bracken (''Pteridium'') is a genus of large, coarse ferns in the family Dennstaedtiaceae. Ferns (Pteridophyta) are vascular plants that undergo alternation of generations, having both large plants that produce spores and small plants that produce sex cells (eggs and sperm) in its life cycle. Brackens are noted for their large, highly divided leaves. They are found on all continents except Antarctica and in all environments except deserts, though their typical habitat is moorland. The genus probably has the widest distribution of any fern in the world. The word ''bracken'' is of Old Norse origin, related to Swedish ''bräken'' and Danish ''bregne'', both meaning fern. In the past, the genus was commonly treated as having only one species, '' Pteridium aquilinum'', but the recent trend is to subdivide it into about ten species. Like other ferns, brackens do not have seeds or fruit, but reproduce by spores. The immature fronds, known as '' fiddleheads'', are sometimes eaten, alt ...

Sitobolium
''Sitobolium punctilobulum'', the eastern hayscented fern or hay-scented fern, is a species of fern native to eastern North America, from Newfoundland west to Wisconsin and Arkansas, and south in the Appalachian Mountains to northern Alabama; it is most abundant in the east of its range, with only scattered populations in the west. It is the sole species in genus ''Sitobolium''. It is a deciduous fern with fronds growing to 40–100 cm (rarely 130 cm) tall and 10–30 cm broad; the fronds are bipinnate, with pinnatifid pinnules about three times as long as broad. It occurs in damp or dry acidic soils in woods or open woods, from sea level up to 1,200 m altitude. ''Sitobolium punctilobulum'' can exhibit varying degrees of phototropism. The common name "Hay-scented Fern" comes from the fact that crushing it produces an aroma of fresh hay. The presence of ''Sitobolium punctilobulum'' influences the dynamics of the understory vegetation of many forests in the eastern ...

Mucura
''Petiveria'' is a genus of flowering plants in the pigeonberry family, Petiveriaceae. The sole species it contains, ''Petiveria alliacea'', is native to Florida and the lower Rio Grande Valley of Texas in the United States, Mexico, Central America, the Caribbean, and tropical South America. Introduced populations occur in Benin and Nigeria. It is a deeply rooted herbaceous perennial shrub growing up to in height and has small greenish piccate flowers. The roots and leaves have a strong acrid, garlic-like odor which taints the milk and meat of animals that graze on it. Common names It is known by a wide number of common names including: ''guinea henweed'', ''guiné'' () in Brazil, ''anamú'' in Cuba, the Dominican Republic, Puerto Rico and Brazil, ''apacin'' in Guatemala, ''mucura'' in Peru, and ''guine'' in many other parts of Latin America, ''feuilles ave'', ''herbe aux poules'', ''petevere a odeur ail'', and, in Trinidad, as ''mapurite'' (pronounced ''Ma-po-reete'') and ''g ...

Dennstaedtia
''Dennstaedtia'' is a mostly tropical and subtropical group of ferns described as a genus in 1801. Hayscented fern, or cup ferns, are common names for some species in this genus. It includes 58 species native to the tropical Americas, Madagascar, southern and eastern Asia, Australia, New Guinea, and the Pacific Islands. Some characteristics of Dennstaedtia: "Fronds homomorphic; stipe grooved above, hairy when young... lamina triangular to oblong, many times pinnate, usually densely hairy, especially on rachis... Veins free, pinnately branching, veinlet not reaching margin, with ''hydathode'' at apex. Sori orbicular, marginal, terminal on each veinlet, separate..." The temperate North-American hay-scented fern, ''Sitobolium punctilobulum'', was formerly classified in ''Dennstaedtia'' and may have been its best-known member. It forms extensive clonal ground-cover colonies on level surfaces in the Appalachian Mountains, Appalachian area. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
