Remusatia
''Remusatia'' is a genus of flowering plants in the family Araceae. It contains 4 known species, one of which was described in 1987. This species was initially placed in genus ''Gonatanthus'' called ''Gonatanthus ornatus''. After the genus had been sunk into ''Remusatia'' its new name was ''Remusatia ornatus'', but it was later changed to ''Remusatia hookeriana''. The species of ''Remusatia'' are native to Asia, Africa, and Australia. They are typically found in subtropical forests and are tuberous plants with heart shaped peltate leaves. A characteristic feature of ''Remusatia'' is its stolons that emerge from the tubers on which is produced bulbils that allow the plant to reproduce. The bulbils cling to animals which allows for them to be distributed and is likely the primary cause for their large distribution. Flowering of many ''Remusatia''s are often rare and bulbils serve as their primary means of reproduction. The spathe In botany, a bract is a modified or specialized le ...

Aroideae
Aroideae is a subfamily of flowering plants in the family (biology), family Araceae. It is the largest subfamily in Araceae and consists of about 72 genera, and 2,300 species. Many Aroideae have spiny pollen grains without a sporopollenin outer exine layer and lacking an aperture (botany), aperture. Genera It includes: Taxonomy May be subdivided into a series of twenty five Tribe (biology), tribes: * Aglaonemateae * Ambrosineae * Anubiadeae * Areae (plant), Areae * Arisaemateae * Arisareae * Arophyteae * Caladieae * Calleae * Callopsideae * Colocasieae * Cryptocoryneae * Culcasieae * Dieffenbachieae * Homalomeneae * Nephthytideae * Peltandreae * Philodendreae * Philonotieae * Pistieae * Schismatoglottideae * Spathicarpeae * Stylochaetoneae * Thomsonieae * Zantedeschieae References {{Taxonbar, from=Q133666 Aroideae, Alismatales subfamilies ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Araceae
The Araceae are a family of monocotyledonous flowering plants in which flowers are borne on a type of inflorescence called a spadix. The spadix is usually accompanied by, and sometimes partially enclosed in, a spathe (or leaf-like bract). Also known as the arum family, members are often colloquially known as aroids. This family of 114 genera and about 3,750 known species is most diverse in the New World tropics, although also distributed in the Old World tropics and northern temperate regions. Description Within the Araceae, species are often rhizomatous or tuberous; many are epiphytic, creeping lianas or vining plants, and the leaves and tissues of the entire plant nearly always contains irritating calcium oxalate crystals or raphides, in varying degrees. The foliage can vary considerably from species to species. The majority of species produce an inflorescence consisting of a spadix (which some compare to a corn cob, in appearance), which is nearly always surrounded ...

Asia
Asia ( , ) is the largest continent in the world by both land area and population. It covers an area of more than 44 million square kilometres, about 30% of Earth's total land area and 8% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilisations. Its 4.7 billion people constitute roughly 60% of the world's population. Asia shares the landmass of Eurasia with Europe, and of Afro-Eurasia with both Europe and Africa. In general terms, it is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a social constructionism, historical and cultural construct, as there is no clear physical and geographical separation between them. A commonly accepted division places Asia to the east of the Suez Canal separating it from Africa; and to the east of the Turkish straits, the Ural Mountains an ...

Africa
Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With nearly billion people as of , it accounts for about of the world's human population. Demographics of Africa, Africa's population is the youngest among all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Based on 2024 projections, Africa's population will exceed 3.8 billion people by 2100. Africa is the least wealthy inhabited continent per capita and second-least wealthy by total wealth, ahead of Oceania. Scholars have attributed this to different factors including Geography of Africa, geography, Climate of Africa, climate, corruption, Scramble for Africa, colonialism, the Cold War, and neocolonialism.

Stolon
In biology, a stolon ( from Latin ''wikt:stolo, stolō'', genitive ''stolōnis'' – "branch"), also known as a runner, is a horizontal connection between parts of an organism. It may be part of the organism, or of its skeleton. Typically, animal stolons are exoskeletons (external skeletons). In botany In botany, stolons are plant stems which grow at the soil surface or just below ground that form adventitious roots at the Node (botany), nodes, and new plants from the buds. Stolons are often called runners. Rhizomes, in contrast, are root-like stems that may either grow horizontally at the soil surface or in other orientations underground. Thus, not all horizontal stems are called stolons. Plants with stolons are called stoloniferous. A stolon is a plant propagation strategy and the complex of individuals formed by a mother plant and all its Cloning, clones produced from stolons form a single genetic individual, a genet (biology), genet. Morphology Stolons may have long or shor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
