Hibiscus Socotranus
''Hibiscus socotranus'' is a species of flowering plant in the family Malvaceae. It is endemic to the island of Socotra in Yemen. It grows in open deciduous succulent shrubland on a limestone escarpment at the western end of the island. It is distinguished from other Socotran ''Hibiscus'' species by its low-growing habit and its fused epicalyx This glossary of botanical terms is a list of definitions of terms and concepts relevant to botany and plants in general.

Grenville Llewellyn Lucas
Grenville 'Gren' Llewellyn Lucas (20 December 1935 – 12 December 2022) was a British botanist, conservationist, and Keeper of the Herbarium and Library at Kew Gardens. Biography Grenville Llewellyn Lucas was born in Cardiff on 20 December 1935. He had an early interest in natural history stimulated by the National Museum of Wales but his first job was working for the Distillers Company on the development and use of plastics and resins. After reading ''The Geography of the Flowering Plants'' by Ronald Good his interest took him to the University of Hull to study botany under Professor Good, where he received a degree in Botany. Gren worked at Kew as a research student for the Colonial Office before taking up a post as Scientific Officer in the East African Herbarium in Nairobi. While in Nairobi he became interested in conservation work. In 1962 he returned to Kew to work on the Flora of Tropical East Africa. He and his wife were both supporters of the Surrey Naturalists' Trus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Endemic
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or bec ...

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 ...

Located in South Arabia, southern Arabia, it borders Saudi Arabia to Saudi Arabia–Yemen border, the north, Oman to Oman–Yemen border, the northeast, the south-eastern part of the Arabian Sea to the east, the Gulf of Aden to the south, and the Red Sea to the west, sharing maritime boundary, maritime borders with Djibouti, Eritrea, and Somalia across the Horn of Africa. Covering roughly 455,503 square kilometres (175,871 square miles), with a coastline of approximately , Yemen is the second largest country on the Arabian Peninsula. Sanaa is its constitutional capital and largest city. Yemen's estimated population is 34.7 million, mostly Arabs, Arab Muslims. It is a member of the Arab League, the United Nations, the Non-Aligned Movement and the Organisation of Islamic Cooperation. Owing to its geographic location, Yemen has been at the crossroads of many civilisations for over 7,000 years. In 1200 BCE, the Sab ...

Socotra Island Xeric Shrublands
The Socotra Island xeric shrublands is a terrestrial ecoregion that covers the large island of Socotra and several smaller islands that constitute the Socotra Archipelago. The archipelago is in the western Indian Ocean, east of the Horn of Africa and south of the Arabian Peninsula. Politically the archipelago is part of Yemen, and lies south of the Yemeni mainland. Socotra has a uniquely diverse ecosystem. The islands are home to a high number of endemic species; up to a third of its plant life is endemic. It has been described as "the most alien-looking place on Earth." Socotra is considered the jewel of biodiversity in the Arabian Sea.FACTBOX-Socotra, jewel of biodiversity in Arabian Sea Reuters, 2008-04-23 In the 1990s, a team of United Nations biologists conducted a survey of ...

Endangered Plants
In September 2016, the International Union for Conservation of Nature (IUCN) listed 3654 endangered plant species. Of all evaluated plant species, 17% are listed as endangered. The IUCN also lists 99 subspecies and 101 varieties as endangered. No subpopulations of plants have been evaluated by the IUCN. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of extinction". An even higher risk is faced by critically endangered species, which meet the quantitative criteria for endangered species. Critically endangered plants are listed separately. There are 6147 plant species which are endangered or critically endangered. Additionally 1674 plant species (7.6% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
