Marattia Laxa
''Marattia'' is a small genus of Basal (phylogenetics), basal, large, fleshy eusporangiate ferns. It is the type genus of the family Marattiaceae, order Marattiales and class Marattiopsida. Formerly considered to be a much larger genus, genetic analysis has shown that ''Marattia'' in the broad sense was paraphyletic, and subsequently the genera ''Ptisana'' and ''Eupodium'' were split off. Except for one species in Hawaii, the genus is neotropical. The plants are large and terrestrial, with more or less erect rhizomes and fronds being 2-5 times pinnate. Sporangia are fused into synangium, synangia, and spores are monolete. Basal chromosome count is ''2n=80''. The type species is ''M. alata''.

Ferns Of The Americas
The ferns (Polypodiopsida or Polypodiophyta) are a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. They differ from mosses 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 ferns. The fern crown group, consisting of the leptosporangiates and eusporangiates, is estimated to have originated in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marattiidae
Marattiaceae is the only family of extant (living) ferns in the order Marattiales. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), Marattiales is the only order in the subclass Marattiidae. The family has six genera and about 110 species. Many are different in appearance from other ferns, having large fronds and fleshy rootstocks. Description The Marattiaceae diverged from other ferns very early in their evolutionary history and are quite different from many plants familiar to people in temperate zones. Many of them have massive, fleshy rootstocks and the largest known fronds of any fern. The Marattiaceae is one of two groups of ferns traditionally known as eusporangiate ferns, meaning that the sporangium is formed from a group of cells as opposed to a leptosporangium in which there is a single initial cell. At least two genera, ''Angiopteris'' and ''Marattia'', have been reported to undergo monoplastidic meiosis rather than polyplastidic meiosis, and are the ...

El Salvador
El Salvador, officially the Republic of El Salvador, is a country in Central America. It is bordered on the northeast by Honduras, on the northwest by Guatemala, and on the south by the Pacific Ocean. El Salvador's capital and largest city is San Salvador. The country's population in 2024 was estimated to be 6 million according to a government census. Among the Mesoamerican nations that historically controlled the region are the Maya peoples, Maya, and then the Cuzcatlan, Cuzcatlecs. Archaeological monuments also suggest an early Olmec presence around the first millennium BC. In the beginning of the 16th century, the Spanish conquest of El Salvador, Spanish Empire conquered the Central American territory, incorporating it into the Viceroyalty of New Spain ruled from Mexico City. However, the Viceroyalty of New Spain had little to no influence in the daily affairs of the isthmus, which was colonized in 1524. In 1609, the area was declared the Captaincy General of Guatemala by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gustav Kunze
Gustav Kunze (4 October 1793 in Leipzig – 30 April 1851 in Leipzig) was a German professor of zoology, an entomologist and botanist with an interest mainly in ferns and orchids. He was editor of some exsiccata series, one issued together with Johann Carl Schmidt under the title ''Deutschlands Schwämme in getrockneten Exemplaren'' (1816-1819).Triebel, D. & Scholz, P. 2001–2024 ''IndExs – Index of Exsiccatae''. Botanische Staatssammlung München: http://indexs.botanischestaatssammlung.de. – München, Germany. Kunze joined the Wernerian Natural History Society in Edinburgh in 1817. He later became Zoology Professor at Leipzig University and in 1837 was appointed director of the Botanical Gardens in Leipzig. Kunze supported the botanical voyages (1823-1828) of Eduard Friedrich Poeppig in North and South America and distributed his plant material in several exsiccata-like series, among others ''Pöppig Coll. Pl. Chil. I''. Later on he supported the botanical voyages (1844-1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Guatemala
Guatemala, officially the Republic of Guatemala, is a country in Central America. It is bordered to the north and west by Mexico, to the northeast by Belize, to the east by Honduras, and to the southeast by El Salvador. It is hydrologically bordered to the south by the Pacific Ocean and to the northeast by the Gulf of Honduras. The territory of modern Guatemala hosted the core of the Maya civilization, which extended across Mesoamerica; in the 16th century, most of this was Spanish conquest of Guatemala, conquered by the Spanish and claimed as part of the viceroyalty of New Spain. Guatemala attained independence from Spain and Mexico in 1821. From 1823 to 1841, it was part of the Federal Republic of Central America. For the latter half of the 19th century, Guatemala suffered instability and civil strife. From the early 20th century, it was ruled by a series of dictators backed by the United States. In 1944, authoritarian leader Jorge Ubico was overthrown by a pro-democratic m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
