Monotypic Poaceae Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical syste ...

Flora Of Honduras
The flora and fauna of Honduras reflects the country's geographical location inside the tropics. This has allowed for diverse species of plants and animals to be adapted, but some of them are now in danger of extinction. This has posed the Honduran government, offices and nature organizations to look after the protection of the local environment, like the creation of nature reserves. Flora The flora of Honduras is varied. Pluvioselva, classified a tropical rain forest, is one of its most impressive vegetal populations. Ecologists designated it "Hygrophilous Megatherm Type", for corresponding to regions of high humidity and constant high temperatures, with a single dominant species, like pines or firs, covering big areas. The eastern part of the country, '' La Mosquitia'', has many creeper and climbing plants, such as lianas. There is a great variety of epiphytes, most strikingly the orchids. Adapted to the humid environment, trees are enormous and do not possess deep roots, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Haiti
The wildlife of Haiti is important to the country because of its biodiversity. According to the World Conservation Monitoring Centre, Haiti is considered to be "one of the most biologically significant countries of the West Indies". With an estimated 5,600 plant species on the island of Hispaniola, some of which only occur in Haiti, 36% are considered as endemic to the island. A mountainous area country, it is situated in the western three-eighths of Hispaniola and shares a border with the Dominican Republic. There are nine life zones, from low desert to high cloud forests, as well as four mountain ranges, and hundreds of rivers and streams and the coral reefs in the seas that surround the islands. Issues of environmental damage, expanding population, deforesting and erosion are of concern; less than 2% of the original forest remains on account of deforestation. This degradation is traced from the 17th century to 19th century starting with the French colonization of the Haiti and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Guatemala
According to ParksWatch and the IUCN, Guatemala is considered the fifth biodiversity hotspot in the world. The country has 14 ecoregions ranging from mangrove forest (4 species), in both ocean littorals, dry forests and scrublands in the eastern highlands, subtropical and tropical rain forests, wetlands, cloud forests in the Verapaz region, mixed forests and pine trees, pine forests in the highlands. Over one third of Guatemala (36.3% or about 39,380 km2) is forested (2005). About half of the forests (49.7% or roughly 19,570 km2) is classified as primary forest which is considered the most biodiversity, biodiverse forest type. Tree species include 17 conifers (pines, Cupressaceae, cypress, including the Endemic (ecology), endemic ''Abies guatemalensis''), the most in any tropical region of the world. Although Guatemala is covered greatly by forests, they still have a deforestation rate of 1.7%, showing that these areas are under a big threat. There have been many conve ...

Flora Of Northeast Brazil
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms '' gut flora'' or '' skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) ...

Panicoideae
Panicoideae is the second-largest subfamily of the grasses with over 3,500 species, mainly distributed in warm temperate and tropical regions. It comprises some important agricultural crops, including sugarcane, maize (or corn), sorghum, and switchgrass. C4 photosynthesis evolved independently a number of times in the subfamily, which presumably had a C3 ancestor. Description The ligule has a fringe of hairs. The inflorescence is branched around a common axis. The spikelets are all alike with two bisexual florets that are joined below the glumes (the outer floral envelopes). The lower glume is shorter than the spikelet. Systematics and taxonomy Within the PACMAD clade of grasses, the Panicoideae are sister to a clade made of the four subfamilies Arundinoideae, Chloridoideae, Danthonioideae, and Micrairoideae. A modern phylogenetic classification divides the Panicoideae in twelve tribes corresponding to monophyletic clades; two genera, '' Chandrasekharania'' and '' Ja ...

Basionym
In the scientific name of organisms, basionym or basyonym means the original name on which a new name is based; the author citation of the new name should include the authors of the basionym in parentheses. The term "basionym" is used in both botany and zoology. In zoology, alternate terms such as original combination or protonym are sometimes used instead. Bacteriology uses a similar term, basonym, spelled without an ''i''. Although "basionym" and "protonym" are often used interchangeably, they have slightly different technical definitions. A basionym is the ''correct'' spelling of the original name (according to the applicable nomenclature rules), while a protonym is the ''original'' spelling of the original name. These are typically the same, but in rare cases may differ. When creating new taxonomic names, there are specific rules about how basionyms can be used. A new combination or name at new rank must be based directly on the original basionym rather than on any intermediate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eduard Hackel
Eduard Hackel (17 March 1850 in Haida, Bohemia – 2 February 1926 in Attersee, Upper Austria) was an Austrian botanist. His father was a veterinarian in Haida (now Nový Bor) in Bohemia. He was married and had one son. Hackel studied at the Polytechnical Institute in Vienna, and became substitute teacher at a high school in St. Pölten in 1869. He became full professor of natural history there upon obtaining his teaching certificate in 1871 and remained in this position until his retirement in 1900. Agrostology He published his first agrostology papers on grasses in 1871 and soon became known as a world expert agrostologist on the grass family (Poaceae). While he himself undertook only a single collecting trip – to Spain and Portugal, he was charged with working up collections of grasses mainly from Japan, Taiwan, New Guinea, Brazil Brazil, officially the Federative Republic of Brazil, is the largest country in South America.
