Asplenium Majoricum
''Asplenium majoricum'' is a tiny fern endemic to Mallorca (Serra de Tramuntana), and some locations in Valencia and south of Catalonia, Spain. It belongs to the family Aspleniaceae. This allotetraploid hybrid (2n = 144 chromosomes) is the result of crossbreeding between the diploid ferns ''Asplenium fontanum'' subsp. ''fontanum'' (2n = 72 chromosomes) and ''Asplenium petrarchae'' subsp. ''bivalens'' (2n = 72 chromosomes), followed by the spontaneous doubling of the number of chromosomes. Its fronds measure between 6 and . The sori are longer than they are wide, with a side indusie, and are located near the central line of the pinnae. Sporulation occurs from March to November. Habitat This small fern lives among the stones of the walls of the terraces and in the crevices of limestone rocks oriented North and Northwest. It likes light but not direct sun. In the dry summer months enters in estivation (summer sleep), dehydrating the fronds until apparently dead. With the first ...

Fern
A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate ( Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid fe ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mallorca
Mallorca, or Majorca, is the largest island in the Balearic Islands, which are part of Spain and located in the Mediterranean. The capital of the island, Palma, is also the capital of the autonomous community of the Balearic Islands. The Balearic Islands have been an autonomous region of Spain since 1983. There are two small islands off the coast of Mallorca: Cabrera (southeast of Palma) and Dragonera (west of Palma). The anthem of Mallorca is "La Balanguera". Like the other Balearic Islands of Menorca, Ibiza, and Formentera, the island is an extremely popular holiday destination, particularly for tourists from the Netherlands, Germany and the United Kingdom. The international airport, Palma de Mallorca Airport, is one of the busiest in Spain; it was used by 28 million passengers in 2017, with use increasing every year since 2012. Etymology The name derives from Classical Latin ''insula maior'', "larger island". Later, in Medieval Latin, this became ''Maiorca'', "the larg ...

Serra De Tramuntana
The Serra de Tramuntana (, es, Sierra de Tramontana) is a mountain range running southwest–northeast which forms the northern backbone of the Spanish island of Mallorca. It is also the name given to the comarca of the same area. On 27 June 2011, the Tramuntana Range was awarded World Heritage Status by UNESCO as an area of great physical and cultural significance. Geography The highest peak is the Puig Major, which at 1,436 meters, is the highest mountain in the Balearic Islands. The second highest peak is Penyal de Migdia which is at 1,398 meters. It is followed by the Puig de Massanella, which stands at 1,364 meters. The mountain range also host the deepest cave of Majorca, the Cova de sa Campana at -358 meters, and the deepest underground lake at -334 meters. The climate in the Tramuntana Range is significantly wetter than the rest of the island, recording as much as 1507 mm (59.3 inches) of precipitation per year, in comparison with some other parts of the islan ...

Valencia
Valencia ( va, València) is the capital of the autonomous community of Valencia and the third-most populated municipality in Spain, with 791,413 inhabitants. It is also the capital of the province of the same name. The wider urban area also comprising the neighbouring municipalities has a population of around 1.6 million, constituting one of the major urban areas on the European side of the Mediterranean Sea. It is located on the banks of the Turia, on the east coast of the Iberian Peninsula, at the Gulf of Valencia, north of the Albufera lagoon. Valencia was founded as a Roman colony in 138 BC. Islamic rule and acculturation ensued in the 8th century, together with the introduction of new irrigation systems and crops. Aragonese Christian conquest took place in 1238, and so the city became the capital of the Kingdom of Valencia. The city's population thrived in the 15th century, owing to trade with the rest of the Iberian Peninsula, Italian ports and other loca ...

Catalonia
Catalonia (; ca, Catalunya ; Aranese Occitan: ''Catalonha'' ; es, Cataluña ) is an autonomous community of Spain, designated as a '' nationality'' by its Statute of Autonomy. Most of the territory (except the Val d'Aran) lies on the northeast of the Iberian Peninsula, to the south of the Pyrenees mountain range. Catalonia is administratively divided into four provinces: Barcelona, Girona, Lleida, and Tarragona. The capital and largest city, Barcelona is the second-most populated municipality in Spain and the fifth-most populous urban area in the European Union. > > > ''Catalonia'' theoretically derived. During the Middle Ages, Byzantine chroniclers claimed that ''Catalania'' derives from the local medley of Goths with Alans, initially constituting a ''Goth-Alania''. Other theories suggest: *''Catalunya'' derives from the term "land of castles", having evolved from the term ''castlà'' or ''castlan'', the medieval term for a castellan (a ruler of a castl ...

Aspleniaceae
The Aspleniaceae (spleenworts) are a family of ferns, included in the order Polypodiales. The composition and classification of the family have been subject to considerable changes. In particular, there is a narrow circumscription, Aspleniaceae s.s. (adopted here), in which the family contains only two genera, and a very broad one, Aspleniaceae s.l., in which the family includes 10 other families kept separate in the narrow circumscription, with the Aspleniaceae s.s. being reduced to the subfamily Asplenioideae. The family has a worldwide distribution, with many species in both temperate and tropical areas. Elongated unpaired sori are an important characteristic of most members of the family. Description Members of the family grow from rhizomes, that are either creeping or somewhat erect, and are usually but not always unbranched, and have scales that usually have a lattice-like (clathrate) structure. In some species, for example ''Asplenium nidus'', the rhizomes form a kind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asplenium Fontanum
''Asplenium fontanum'', commonly known as fountain spleenwort or smooth rock spleenwort, is a species of fern in the family Aspleniaceae, native to rocky areas in Western Europe. Description ''Asplenium fontanum'' is a rhizomatous fern with fronds up to long grouped in bundles. The rhizomes are clad in dark brown scales. The fronds are born on stems that may be as long as the blades. These are pinnate, with eight to twenty toothed pinnules up to long on each side, the longest being in the middle of the blade. The basal part of the stem is brown and the remainder of the stem and the blade are bright green. The sori are distributed in groups of two or three on the underside of the pinnules. Taxonomy A global phylogeny of ''Asplenium'' published in 2020 divided the genus into eleven clades, which were given informal names pending further taxonomic study. ''A. fontanum'' belongs to the "''A. incisum'' subclade" of the "''Schaffneria'' clade". The ''Schaffneria'' clade ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asplenium Petrarchae
''Asplenium petrarchae'' is a tiny fern of the family Aspleniaceae. Its fronds are densely pubescent-glandular with length between 5 and 14 cm. Petiole less than the sheet of dark brown and shiny. Sores along the central line of the pinnae, subelliptical and confluent when mature. It sporulates almost throughout the year. Habitat It lives among the stones of the walls of the terraces and in crevices of limestone rocks. It loves the light and supports a few hours of sunshine in the early hours and tangential final hours of the day. It hates the rain directly on its fronds, preferring the moisture comes to its roots through the soil soaked by seepage of rainwater. For this usually grow well inside the crevices of the rocks and between the stones of the walls of the terraces, where no rain falls over. Although well-supported long periods of drought, the driest months and hot summer enters in estivation Aestivation ( la, aestas (summer); also spelled estivation in Amer ...

Asplenium Ceterach
''Asplenium ceterach'' ( syn. ''Ceterach officinarum'') is a fern species commonly known as rustyback. Description It is characterised by a short rhizome which gives rise to several green fronds that have a pinnated lamina with trichomes on the abaxial (lower) surface, but not the adaxial (upper) one. These trichomes (hairs) are orange-brown in colour, hence the name "rustyback". The petiole is shorter than the corpus of the leaf. Taxonomy Linnaeus was the first to describe rustyback with the binomial ''Asplenium ceterach'' in his ''Species Plantarum'' of 1753. A global phylogeny of ''Asplenium'' published in 2020 divided the genus into eleven clades, which were given informal names pending further taxonomic study. ''A. scolopendrium'' belongs to the "''Ceterach'' subclade" of the "''Phyllitis'' clade". Members of the ''Phyllitis'' clade have undivided or pinnatifid leaf blades with a thick, leathery texture, persistent scales on their stalk, and often possess anastomosing ...

Asplenium
''Asplenium'' is a genus of about 700 species of ferns, often treated as the only genus in the family Aspleniaceae, though other authors consider '' Hymenasplenium'' separate, based on molecular phylogenetic analysis of DNA sequences, a different chromosome count, and structural differences in the rhizomes. The type species for the genus is ''Asplenium marinum''. The most common vernacular name is spleenworts, applied to the more "typical" species. '' A. nidus'' and several similar species are called bird's-nest ferns, the ''Camptosorus'' group is known as walking ferns, and distinct names are applied to some other particularly well-known species. Taxonomy and genetics Many groups of species have been separated from ''Asplenium'' as segregate genera. These include ''Camptosorus'', ''Ceterach'', ''Phyllitis'', and ''Tarachia'', but these species can form hybrids with other ''Asplenium'' species and because of this are usually included in a more broadly defined ''Asplenium''.
