Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...

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] |
Malvaceae
Malvaceae (), or the mallows, is a family of flowering plants estimated to contain 244 genera with 4225 known species. Well-known members of economic importance include Theobroma cacao, cacao, Cola (plant), cola, cotton, okra, Hibiscus sabdariffa, roselle and durian. There are also some genera containing familiar ornamentals, such as ''Alcea'' (hollyhock), ''Malva'' (mallow), and ''Tilia'' (lime or linden tree). The genera with the largest numbers of species include ''Hibiscus'' (434 species), ''Pavonia (plant), Pavonia'' (291 species), ''Sida (plant), Sida'' (275 species), ''Ayenia'' (216 species), ''Dombeya'' (197 species), and ''Sterculia'' (181 species). Taxonomy and nomenclature The circumscription of the Malvaceae is controversial. The traditional Malvaceae ''sensu stricto'' comprise a very homogeneous and cladistically Monophyly, monophyletic group. Another major circumscription, Malvaceae ''sensu lato'', has been more recently defined on the basis that genetics studies ha ...

Tiliaceae
Tiliaceae () is a family of flowering plants. It is not a part of the APG, APG II and APG III classifications, being sunk in Malvaceae mostly as the subfamilies Tilioideae, Brownlowioideae and Grewioideae, but has an extensive historical record of use. All through its existence the family has had a very lively history, with various authors taking very different views on what should be part of this family. As a result, it is recommended when this name is encountered to check what the author means. However, in the northern temperate regions the name is unambiguous as the only representative is ''Tilia'', the lime or linden. APG II system The APG II system, does not recognise this as a family but submerges it in the Malvaceae sensu lato, which unites the four families Bombacaceae, Malvaceae sensu stricto, Sterculiaceae and Tiliaceae. Modern botanical taxonomy, such as the relevant volume in the Kubitzki series which conforms to APG, treats most of the plants that tradit ...

Sparrmanniaceae
Sparrmanniaceae is a segregate, probably obsolete, plant family, containing plants which have more commonly been classified in Malvaceae or Tiliaceae. In the most recent proposed circumscription, that of Cheek ex Heywood et al., it corresponds to subfamily Grewioideae of the APG family Malvaceae.Kubitzki & Bayer, Families and Genera of Vascular Plants V (2005) Genera formerly included in the Sparrmanniaceae: * '' Ancistrocarpus'' * '' Apeiba'' * '' Clappertonia'' * '' Colona'' * '' Corchorus'' * '' Desplatsia'' * '' Duboscia'' * '' Eleutherostylis'' * '' Entelea'' * '' Erinocarpus'' * '' Glyphaea'' * '' Goethalsia'' * ''Grewia ''Grewia'' is a large flowering plant genus in the mallow family (biology), family Malvaceae, in the expanded sense as proposed by the Angiosperm Phylogeny Group.

Socotra
Socotra, locally known as Saqatri, is a Yemeni island in the Indian Ocean. Situated between the Guardafui Channel and the Arabian Sea, it lies near major shipping routes. Socotra is the largest of the six islands in the Socotra archipelago as it comprises around 95% of the landmass of the archipelago. It lies south of the Arabian Peninsula and east of the Horn of Africa. The inhabitants of the island are called Soqotri people, Socotrans, and they speak Arabic and Soqotri language, Soqotri. Socotra is home to a high number of unique species that are endemism, endemic to it. Up to a third of its plant life is unique. Due to the island's unusual geography, it has been described as "the most alien-looking place on Earth". The island measures in length and across at its widest. In 2008, Socotra was recognised as a UNESCO World Heritage Site. The island is under the control of the Southern Transitional Council (STC), a United Arab Emirates-backed, pro-Presidential Leadership Co ...

Hajhir Mountains
The Hajhir massif is a mountain range situated on the island of Socotra, Yemen. It is the highest point of the island. Geography The granite spires of the Hajhir massif are located in the hinterland of Socotra and are most easily accessed via the valley approaches north of the coastal town of Hadibo. The highest point of the range is the peak of Mashanig which lies at approximately above sea level. Other peaks of local prominence include Girhimitin, Hazrat Muqadriyoun and Herem Hajhir. Etymology The name "Hajhir" ( Soqotri: ), sometimes transliterated as "Hagghier" or "Hagher" in English, likely derives from the Arabic "ḥijr" (, meaning "stone"). Other possible origins of the range's name include the word "hajar" (, meaning "to flee"). The name "Mashanig" (Soqotri: , meaning "the split one"), likely derives from the Arabic verb "inshaq" (, meaning "to split"), from which one gets the word "munshuq" (, meaning "splittist").

Grewia
''Grewia'' is a large flowering plant genus in the mallow family (biology), family Malvaceae, in the expanded sense as proposed by the Angiosperm Phylogeny Group. Formerly, ''Grewia'' was placed in either the family Tiliaceae or the Sparrmanniaceae. However, these were both not monophyletic with respect to other Malvales - as already indicated by the uncertainties surrounding placement of ''Grewia'' and similar genera - and have thus been merged into the Malvaceae. Together with the bulk of the former Sparrmanniaceae, ''Grewia'' is in the subfamily Grewioideae and therein the tribe (biology), tribe Grewieae, of which it is the type genus. The genus was named by Carl Linnaeus, in honor of the botanist Nehemiah Grew (1641-1712) from England. Grew was one of the leading plant anatomists and microscope researchers of his time, and his study of pollen laid the groundwork for modern-day palynology.
