Spinacia
''Spinacia'' is a flowering plant genus in the subfamily Chenopodioideae of the family Amaranthaceae. The most common member is spinach. Description The species in genus ''Spinacia'' are annual or biennial herbs. Plants are always glabrous. Their stems grow erect and are unbranched or sparsely branched. The alternate leaves consist of a petiole and a simple blade. The basal leaves are often forming a rosette. The leaf blade is triangular-hastate to ovate, sometimes with elongated lobes, with entire or dentate margins and an acute apex. The plants are usually dioecious, (rarely monoecious). The male flowers are in glomerules forming interrupted terminal spike-like panicles. They consist of 4-5 oblong perianth segments and 4-5 stamens. Female flowers are in glomerules sitting in the leaf axils. Enclosed by 2 accrescent or united bracteoles, without perianth, they consist of an ovary with 4-5 filiform stigmas. In fruit, bracteoles become enlarged and hardened, sometimes with d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spinacia Oleracea
Spinach (''Spinacia oleracea'') is a leafy green flowering plant native to central and western Asia. It is of the order Caryophyllales, family Amaranthaceae, subfamily Chenopodioideae. Its leaves are a common edible vegetable consumed either fresh, or after storage using preservation techniques by canning, freezing, or dehydration. It may be eaten cooked or raw, and the taste differs considerably; the high oxalate content may be reduced by steaming. It is an annual plant (rarely biennial), growing as tall as . Spinach may overwinter in temperate regions. The leaves are alternate, simple, ovate to triangular, and very variable in size: long and broad, with larger leaves at the base of the plant and small leaves higher on the flowering stem. The flowers are inconspicuous, yellow-green, in diameter, and mature into a small, hard, dry, lumpy fruit cluster across containing several seeds. In 2018, world production of spinach was 26.3 million tonnes, with China alone accounting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chenopodioideae
The Chenopodioideae are a subfamily of the flowering plant family Amaranthaceae in the APG III system, which is largely based on molecular phylogeny, but were included - together with other subfamilies - in family Chenopodiaceae in the Cronquist system. Food species comprise Spinach (''Spinacia oleracea''), Good King Henry (''Blitum bonus-henricus''), several '' Chenopodium'' species (Quinoa, Kañiwa, Fat Hen), Orache (''Atriplex spp.''), and Epazote (''Dysphania ambrosioides''). The name is Greek for goosefoot, the common name of a genus of plants having small greenish flowers. Description The Chenopodioideae are annual or perennial herbs, subshrubs, shrub or small trees. The leaves are usually alternate and flat. The flowers are often unisexual. Many species are monoecious or have mixed inflorescences of bisexual and unisexual flowers. Some species are dioecious, like ''Spinacia'', '' Grayia'', '' Exomis'', and ''Atriplex''. In several species of tribe Atripliceae, t ...

Amaranthaceae
Amaranthaceae is a family of flowering plants commonly known as the amaranth family, in reference to its type genus ''Amaranthus''. It includes the former goosefoot family Chenopodiaceae and contains about 165 genera and 2,040 species, making it the most species-rich lineage within its parent order, Caryophyllales. Description Vegetative characters Most species in the Amaranthaceae are annual or perennial herbs or subshrubs; others are shrubs; very few species are vines or trees. Some species are succulent. Many species have stems with thickened nodes. The wood of the perennial stem has a typical "anomalous" secondary growth; only in subfamily Polycnemoideae is secondary growth normal. The leaves are simple and mostly alternate, sometimes opposite. They never possess stipules. They are flat or terete, and their shape is extremely variable, with entire or toothed margins. In some species, the leaves are reduced to minute scales. In most cases, neither basal nor terminal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blitum
''Blitum'' is a genus of flowering plants in the amaranth family Amaranthaceae, subfamily Chenopodioideae. It is closely related to genus ''Spinacia''. Its 12 species were traditionally placed in the genera '' Chenopodium'', ''Monolepis'', or ''Scleroblitum''. The species of genus ''Blitum'' occur in Asia, Europe, North Africa, the Americas, and Australia. Description The species in genus ''Blitum'' are non-aromatic annual or perennial herbs. They are glabrous, or sometimes covered with stipitate vesicular hairs, young plants may be sticky. From the base emerge several erect, ascending or prostrate stems, that are unbranched or sparsely branched. The alternate leaves consist of a petiole and a simple blade. The basal leaves are often long-petiolate and forming a rosette. The leaf blade is thin oder slightly fleshy, and may be triangular, triangular-hastate, triangular-lanceolate, or spathulate, with entire to dentate margins. The inflorescences consist of spicately arranged ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the world population, human population, was the site of many of the cradle of civilization, first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia 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. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediterranean
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide.

Subtropical
The subtropical zones or subtropics are geographical and climate zones to the north and south of the tropics. Geographically part of the temperate zones of both hemispheres, they cover the middle latitudes from to approximately 35° north and south. The horse latitudes lie within this range. Subtropical climates are often characterized by hot summers and mild winters with infrequent frost. Most subtropical climates fall into two basic types: humid subtropical ( Koppen climate Cfa), where rainfall is often concentrated in the warmest months, for example Southeast China and the Southeastern United States, and dry summer or Mediterranean climate ( Koppen climate Csa/Csb), where seasonal rainfall is concentrated in the cooler months, such as the Mediterranean Basin or Southern California. Subtropical climates can also occur at high elevations within the tropics, such as in the southern end of the Mexican Plateau and in Da Lat of the Vietnamese Central Highlands. The six c ...
