Dennstaedtiaceae
Dennstaedtiaceae is one of fifteen families in the order Polypodiales, the most derived families within fern, 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 indusium, 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 monophyletic, 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. Distribution of ...

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] |

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 Aquilinum
''Pteridium aquilinum'', commonly called bracken, brake, pasture brake, common bracken, and also known as eagle fern, is a species of fern occurring in temperate and subtropical regions in both hemispheres. Originally native to Eurasia and North America, the extreme lightness of its spores has led to it achieving a cosmopolitan distribution. Description Common bracken is a herbaceous perennial plant, deciduous in winter. The large, roughly triangular fronds are produced singly, arising upwards from an underground rhizome, and grow to tall; the main stem, or stipe, is up to in diameter at the base. It dies back to ground level in autumn. The rhizome grows up to deep, about in diameter, and up to long. Because it regrows in the spring from an underground rhizome, ''P. aquilinum'' tends to be found in dense colonies of genetically identical fronds. Such colonies can be as much as 650 years of age, with individual rhizomes living up to 72 years. One colony at Raakkyla, North Ka ...

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 ...

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] |
