Zizkaea
''Zizkaea'' is a monotypic genus of flowering plants belonging to the family Bromeliaceae. It only contains one known species, ''Zizkaea tuerckheimii''. Taxonomy The genus name of ''Zizkaea'' is in honour of Georg Zizka (b. 1955), a German evolutionary botanist and also specialist in Bromeliaceae. The Latin specific epithet of ''tuerckheimii'' refers to Hans von Türckheim (1853-1920), a German plant collector. Both the genus and the species were first described and published in Phytotaxa Vol.279 on page 55 in 2016. Distribution It is native to the Dominican Republic and Haiti on the island of Hispaniola Hispaniola (, also ) is an island between Geography of Cuba, Cuba and Geography of Puerto Rico, Puerto Rico in the Greater Antilles of the Caribbean. Hispaniola is the most populous island in the West Indies, and the second-largest by List of C ....

Tillandsioideae
Tillandsioideae is a subfamily of plants in the bromeliad family Bromeliaceae. This subfamily contains the greatest number of species (about 1,400). Most are Epiphyte, epiphytic or Lithophyte, lithophytic, growing in trees or on rocks where they absorb water and nutrients from the air. Spanish moss of the genus ''Tillandsia'' is a well-known species. Bromeliads in the genera ''Guzmania'' and ''Vriesea'' are the more commonly cultivated members of this subfamily. Description Nearly all bromeliads have specialized Cell (biology), cell groups called trichomes which form scales on the foliage. The trichomes occurring on Tillandsioideae may cover the plants so completely that they appear grey or white, like Spanish moss. In addition to absorbing nutrients, the trichomes may serve to insulate the plant from freezing weather. Plants in this group have smooth or entire leaf margins, unusual color and markings, with many producing fragrant flowers. All their leaves are spineless (un ...

Bromeliaceae
The Bromeliaceae (the bromeliads) are a family of monocot flowering plants of about 80 genera and 3700 known species, native mainly to the tropical Americas, with several species found in the American subtropics and one in tropical west Africa, '' Pitcairnia feliciana''. It is among the basal families within the Poales and is the only family within the order that has septal nectaries and inferior ovaries.Judd, Walter S. Plant systematics a phylogenetic approach. 3rd ed. Sunderland, MA: Sinauer Associates, Inc., 2007. These inferior ovaries characterize the Bromelioideae, a subfamily of the Bromeliaceae. The family includes both epiphytes, such as Spanish moss ('' Tillandsia usneoides''), and terrestrial species, such as the pineapple ('' Ananas comosus''). Many bromeliads are able to store water in a structure formed by their tightly overlapping leaf bases. However, the family is diverse enough to include the tank bromeliads, grey-leaved epiphyte ''Tillandsia'' species tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic Genus
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 system. ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Plant Names Index
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized Author citation (botany), author abbreviations. These were initially based on Authors of Plant Names, Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew (Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium (Australian Plant Name Index, APNI). The IPNI database is a collection of the names registered by the three cooperating ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plants Described In 2016
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts, mosses, lycophytes, ferns, conifers and other gymnosper ...

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] |
