Tecticornia Pterygosperma
''Tecticornia'' is a genus of succulent, salt tolerant plants largely endemic to Australia. Taxa in the genus are commonly referred to as samphires. In 2007, the genus ''Halosarcia'', along with three other Australian genera (''Pachycornia'', ''Sclerostegia'' and ''Tegicornia'') was incorporated into the genus. Description The species of ''Tecticornia'' grow as annual or perennial herbs, subshrubs or small shrubs. Stems are branched, glabrous and appear jointed. The opposite leaves are fleshy, glabrous, connate in the lower part and cup-like or collar-like stem-clasping, with minute (0–3 mm long) two-lobed to triangular leaf blades. The spike-shaped inflorescences consist of opposite bracts, mostly connate and stem-clasping, free in some species. Their blades are cup- or collar-like or deltoid to semi-circular scales. In the axil of each bract, there are three to five (rarely one or seven) flowers, free or sometimes fused to each other, to the bract, and to the infl ...

Tecticornia Pergranulata
''Tecticornia pergranulata'' (commonly known as the blackseed glasswort or blackseed samphire) is a succulent halophytic plant species in the family Chenopodiaceae, native to Australia. This plant is commonly tested in labs involving its C3 photosynthesis and its unique resistance to salinity and adversity. Background ''Tecticornia pergranulata'' is a species of small erect sub-shrubs with articulate, succulent stems that grow around 1 meter in height. They also contain swollen branches with small leaf lobes and are mostly located on the boundaries of salt lakes and salty swamps all across southern Australia. They are most well known for their ability to adapt to high salinity levels and flooding. Adaptations When dealing with floods, this species has a unique method it uses to survive. Through research done by Sarah M Rich, Martha Ludwig, and Timothy Colmer, it was discovered that photosynthesis that takes place within ''Tecticornia pergranulata'' roots allows this species ...

Perianth
The perianth (perigonium, perigon or perigone in monocots) is the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla (petals) or tepals when called a perigone. The term ''perianth'' is derived from Greek περί (, "around") and άνθος (, "flower"), while ''perigonium'' is derived from περί () and γόνος (, "seed, sex organs"). In the mosses and liverworts (Marchantiophyta), the perianth is the sterile tubelike tissue that surrounds the female reproductive structure (or developing sporophyte). Flowering plants In flowering plants, the perianth may be described as being either dichlamydeous/heterochlamydeous in which the calyx and corolla are clearly separate, or homochlamydeous, in which they are indistinguishable (and the sepals and petals are collectively referred to as tepals). When the perianth is in two whorls, it is described as biseriate. While the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salicornia
''Salicornia'' is a genus of succulent, halophytic (salt tolerant) flowering plants in the family Amaranthaceae that grow in salt marshes, on beaches, and among mangroves. ''Salicornia'' species are native to North America, Europe, Central Asia, and southern Africa. Common names for the genus include glasswort, pickleweed, picklegrass, and marsh samphire; these common names are also used for some species not in ''Salicornia''. To French speakers in Atlantic Canada, they are known colloquially as ''titines de souris'' ('mouse tits'). The main European species is often eaten, called marsh samphire in Britain, and the main North American species is occasionally sold in grocery stores or appears on restaurant menus as sea beans, samphire greens or sea asparagus. Description The ''Salicornia'' species are small annual herbs. They grow prostrate to erect, their simple or branched stems are succulent, hairless, and appear to be jointed. The opposite leaves are strongly reduced to sma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarcocornia
''Sarcocornia'' is a formerly recognized genus of flowering plants in the amaranth family, Amaranthaceae. Species are known commonly as samphires, glassworts, or saltworts. Molecular phylogenetic studies have shown that when separated from ''Salicornia'', the genus is paraphyletic, since ''Salicornia'' is embedded within it, and ''Sarcocornia'' has now been merged into a more broadly circumscribed ''Salicornia''. When separated from ''Salicornia'', the genus has a cosmopolitan distribution, and is most diverse in the Cape Floristic Region of South Africa. Description Species formerly placed in ''Sarcocornia'' are perennial herbs, subshrubs or shrubs. They are taking an erect or prostrate, creeping form. The new stems are fleshy and divided into joint-like segments. Older stems are woody and not segmented. The oppositely arranged leaves are borne on fleshy, knobby petioles, their base decurrent and connate (thus forming the segments), the blades forming small, triangular t ...

Salicornioideae
The Salicornioideae are a subfamily of the flowering plant family Amaranthaceae (''sensu lato'', including the Chenopodiaceae). Important characters are succulent, often articulated stems, strongly reduced leaves, and flowers aggregated in thick, dense spike-shaped thyrses. These halophyte, halophytic plants are distributed worldwide. Many are edible (see Samphire) Description The Salicornioideae are Annual plant, annual or Perennial plant, perennial herbs, subshrubs, or low shrubs. Their stems are glabrous and often apparently jointed. The alternate or opposite leaf, leaves are fleshy, glabrous, often basally connate and stem-clasping (thus forming the joints), with missing or short free leaf blades. The spike-shaped inflorescences consist of alternate or opposite bracts, these are often connate and stem-clasping, sometimes free. In the axil of each bract, there are one to five (rarely to twelve) flowers, free or sometimes fused to each other, to the bract, and to the inf ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Africa
Although tropical Africa is mostly familiar to the West for its rainforests, this biogeographic realm of Africa is far more diverse. While the tropics are thought of as regions with hot moist climates, which are caused by latitude and the tropical rain belt, the geology of areas, particularly mountain chains, and geographical relation to continental and regional scale winds impact the overall areas , also, making the tropics run from arid to humid in West Africa. The area is currently experiencing the negative effects of rapid human population growth.Zinkina J., Korotayev A.br>Explosive Population Growth in Tropical Africa: Crucial Omission in Development Forecasts (Emerging Risks and Way Out). ''World Futures'' 70/2 (2014): 120–139 Overview Tropical rainforests are moist forests of semi-deciduous plants distributed across nine West African countries.

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has some large marginal or regional seas such as the Arabian Sea, Laccadive Sea, Bay of Bengal, and Andaman Sea. Etymology The Indian Ocean has been known by its present name since at least 1515 when the Latin form ''Oceanus Orientalis Indicus'' ("Indian Eastern Ocean") is attested, named after Indian subcontinent, India, which projects into it. It was earlier known as the ''Eastern Ocean'', a term that was still in use during the mid-18th century (see map), as opposed to the ''Western Ocean'' (Atlantic Ocean, Atlantic) before the Pacific Ocean, Pacific was surmised.

Tecticornia Indica
''Tecticornia indica'' is a species of plant that is succulent and halophyte (salt tolerant) which grows in salt marshes on tropical areas of the world. This plant belongs to the Chenopodiaceae, which are now included in family Amaranthaceae. These plants lack leaves. Stem & branches are modified as main photosynthetic structures. The Stem is jointed. Flowers are said to be fine and present in scales. The fruit of this plant is round and green. Capsule is hard and it contains many seeds that are hairy. The seeds are dimorphic. The Walmajarri The Walmadjari (Walmajarri) people, also known as Tjiwaling and Wanaseka, are an Aboriginal Australian people of the Kimberley region of Western Australia. Name The two names reflect different Walmadjari preferences. Their western bands accept ... people of the southern Kimberley call this plant ''Mungily''.
