Dendrosicyos
''Dendrosicyos'' is a monotypic genus in the plant family (biology), family Cucurbitaceae. The only species is ''Dendrosicyos socotranus'', the cucumber tree. The species is endemism, endemic to the island of Socotra in Yemen, and is the only species in the Cucurbitaceae to grow in a tree form. The species name was originally spelled ''D. socotrana'', but this is corrected to masculine grammatical gender according to the International Code of Nomenclature for algae, fungi, and plants. Features It has a bulbous trunk and a small crown. It was first described by Isaac Bayley Balfour in 1882. A recent molecular phylogenetic analysis of the family Cucurbitaceae found that the ''Dendrosicyos'' lineage is about twice as old as the island, and thus seems to be an island relic of a progenitor lineage that became extinct on the mainland. The leaves are nearly round, covered with fine bristles, and slightly toothed. The yellow flowers (3 cm), males and females are present on the sam ...

Cucurbitaceae
The Cucurbitaceae, also called cucurbits or the gourd family, are a plant family consisting of about 965 species in around 95 genera, of which the most important to humans are: *''Cucurbita'' – squash, pumpkin, zucchini, some gourds *''Lagenaria'' – calabash, and others that are inedible *''Citrullus'' – watermelon (''C. lanatus'', ''C. colocynthis'') and others *''Cucumis'' – cucumber (''C. sativus''), various melons and vines *''Momordica'' – bitter melon *''Luffa'' – the common name is also luffa, sometimes spelled loofah (when fully ripened, two species of this fibrous fruit are the source of the loofah scrubbing sponge) *''Cyclanthera'' – Caigua The plants in this family are grown around the tropics and in temperate areas, where those with edible fruits were among the earliest cultivated plants in both the Old and New Worlds. The family Cucurbitaceae ranks among the highest of plant families for number and percentage of species used as human food. The name ' ...

Socotra
Socotra or Soqotra (; ar, سُقُطْرَىٰ ; so, Suqadara) is an island of the Republic of Yemen in the Indian Ocean, under the ''de facto'' control of the UAE-backed Southern Transitional Council, a secessionist participant in Yemen’s ongoing civil war. Lying between the Guardafui Channel and the Arabian Sea and near major shipping routes, Socotra is the largest of the four islands in the Socotra archipelago. Since 2013, the archipelago has constituted the Socotra Governorate. The island of Socotra represents around 95% of the landmass of the Socotra archipelago. It lies south of the Arabian Peninsula, but is considered to be part of Africa. The island is isolated and 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." The island measures in length and in width. In 2008 Socotra was recognised as a UNESCO World Heritage Site. In 2018, the United Arab Emirates invaded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cissus Subaphylla
''Cissus subaphylla'' is a low shrub in the grape family Vitaceae. It is endemic to the Yemeni island of Socotra. The plant grows mainly in dry, low-lying areas on alluvial fans or on limestone slopes, and is rarely found above elevations of , where it is replaced by ''C. hamaderohensis''. It does not have the climbing habit of other ''Cissus'' species, and its stems are flattened and gray-green in colour, with relatively small leaves and flowers. The tangled mats of ''C. subaphylla'' stems act as a protective covering for plants regularly eaten by goats and other browsing animals; the plant is thus important in the rehabilitation of species such as ''Dendrosicyos'', ''Maerua'' and ''Commiphora''.

Pachycaul
Pachycauls are plants with a disproportionately thick Trunk (botany), trunk for their height, and few branches. This can be the product of exceptional primary growth (as with Arecaceae, palms and cycads) or disproportioate secondary growth as with Adansonia. The word is derived from the Greek language, Greek ''pachy-'' meaning thick or stout, and Latin language, Latin ''caulis'' meaning the stem. All of the tree (and treelike) species of cactus are pachycauls, as are most Arecaceae, palms, Cycads and pandans. The most extreme pachycauls are the floodplains, or riverbottom variety of the African Palmyra (Borassus aethiopum) with primary growth up to seven feet (2.1 meters) in thickness, and the Coquito Palm (Jubaea chilensis) with primary growth up to six feet (1.8 meters) thick. The most pachycaulous cycad is Cycas thouarsii at up to five feet (150 centimeters) in diameter. The tallest pachycaul is the Andean Wax Palm (Ceroxylon quindiuense) at up to 220 feet (66 meters). and abo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monoecious
Monoecy (; adj. monoecious ) is a sexual system in seed plants where separate male and female cones or flowers are present on the same plant. It is a monomorphic sexual system alongside gynomonoecy, andromonoecy and trimonoecy. Monoecy is connected to anemophily. It can prevent self-pollination in an individual flower but cannot prevent self-pollination between male and female flowers on the same plant. Monoecy in angiosperms has been of interest for evolutionary biologists since Charles Darwin. Terminology Monoecious comes from the Greek words for one house. History The term monoecy was first introduced in 1735 by Carl Linnaeus. Darwin noted that the flowers of monoecious species sometimes showed traces of the opposite sex function. Monoecious hemp was first reported in 1929. Occurrence Monoecy is most common in temperate climates and is often associated with inefficient pollinators or wind-pollinated plants. It may be beneficial to reducing pollen-stigma interferenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cucurbitacin
Cucurbitacin is a class of biochemical compounds that some plants – notably members of the pumpkin and gourd family, Cucurbitaceae – produce and which function as a defence against herbivores. Cucurbitacins are chemically classified as triterpenes, formally derived from cucurbitane, a triterpene hydrocarbon – specifically, from the unsaturated variant cucurbit-5-ene, or 19(10→9β)-abeo-10α-lanost-5-ene. They often occur as glycosides. They and their derivatives have been found in many plant families (including Brassicaceae, Cucurbitaceae, Scrophulariaceae, Begoniaceae, Elaeocarpaceae, Datiscaceae, Desfontainiaceae, Polemoniaceae, Primulaceae, Rubiaceae, Sterculiaceae, Rosaceae, and Thymelaeaceae), in some mushrooms (including Russula and Hebeloma) and even in some marine mollusks. Cucurbitacins may be a taste deterrent in plants foraged by some animals and in some edible plants preferred by humans, like cucumbers and zucchinis. In laboratory research, cucurbitacins ...

Djibouti
Djibouti, ar, جيبوتي ', french: link=no, Djibouti, so, Jabuuti officially the Republic of Djibouti, is a country in the Horn of Africa, bordered by Somalia to the south, Ethiopia to the southwest, Eritrea in the north, and the Red Sea and the Gulf of Aden to the east. The country has an area of . In antiquity, the territory, together with Ethiopia, Eritrea and Somaliland, was part of the Land of Punt. Nearby Zeila, now in Somaliland, was the seat of the medieval Adal and Ifat Sultanates. In the late 19th century, the colony of French Somaliland was established following treaties signed by the ruling Dir Somali sultans with the French, and its railroad to Dire Dawa (and later Addis Ababa) allowed it to quickly supersede Zeila as the port for southern Ethiopia and the Ogaden. It was renamed the French Territory of the Afars and the Issas in 1967. A decade later, the Djiboutian people voted for independence. This officially marked the establishment of the ''Rep ...

Phloem
Phloem (, ) is the living biological tissue, tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as ''photosynthates'', in particular the sugar sucrose, to the rest of the plant. This transport process is called translocation. In trees, the phloem is the innermost layer of the bark (botany), bark, hence the name, derived from the Ancient Greek word (''phloiós''), meaning "bark". The term was introduced by Carl Nägeli in 1858. Structure Phloem tissue consists of conducting Cell (biology), cells, generally called sieve elements, Ground tissue#Parenchyma, parenchyma cells, including both specialized companion cells or albuminous cells and unspecialized cells and supportive cells, such as fibres and sclereids. Conducting cells (sieve elements) Sieve elements are the type of cell that are responsible for transporting sugars throughout the plant. At maturity they lack a Cell nucleus, nucleus and have very few organelles, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
