Aspidistra Alata
''Aspidistra alata'' is a species of flowering plant. ''A. alata'' grows in evergreen and semideciduous forests on slopes of limestone mountains in Vietnam. Its name is derived from the Latin language, Latin ''alatus'', meaning "winged", referring to its thin keels on perianth, perigone lobes. Description This species is a perennial herb. Its rhizome is creeping, with a diameter of between , which is densely covered with fibrous remnants of cataphylls. Its leaves are distally huddled, each being between long; the petiole (botany), petiole measuring between . Its wikt:lamina, lamina is linear, measuring between by , and basally gradually tapers towards the petiole. Flowers are found solitary, with a decumbent Peduncle (botany), peduncle, in size, showing two bracts halfway and one at its base. The Tepal, perigone is greenish-violet to reddish; the flower's tube is urceolate, long. It counts with 6 lobes, which are Ligule, ligulate with rounded and reflexed tips, , each with 4 ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ...

Aspidistra
''Aspidistra'' is a genus of flowering plants in the family Asparagaceae, subfamily Nolinoideae, native to eastern and southeastern Asia, particularly China and Vietnam. They grow in shade under trees and shrubs. Their leaves arise more or less directly from ground level, where their flowers also appear. The number of species known has increased considerably from the 1980s onwards, with around 100 accepted . ''Aspidistra elatior'' is common worldwide as a foliage house plant that is very tolerant of neglect. It and other species can also be grown in shade outside, where they are generally hardy to . Description Species of ''Aspidistra'' are perennial herbaceous plants growing from rhizomes. The leaves are either solitary or are grouped in small "tufts" of two to four. They arise more or less directly from the rhizome, rather than being borne on stems. Each leaf has a long stalk ( petiole) and a blade with many veins. The flowering stem ( scape) is usually very short so that th ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Guangxi
Guangxi (; ; Chinese postal romanization, alternately romanized as Kwanghsi; ; za, Gvangjsih, italics=yes), officially the Guangxi Zhuang Autonomous Region (GZAR), is an Autonomous regions of China, autonomous region of the People's Republic of China, located in South China and bordering Vietnam (Hà Giang Province, Hà Giang, Cao Bằng Province, Cao Bằng, Lạng Sơn Province, Lạng Sơn, and Quảng Ninh Provinces) and the Gulf of Tonkin. Formerly a Provinces of China, province, Guangxi became an autonomous region in 1958. Its current capital is Nanning. Guangxi's location, in mountainous terrain in the far south of China, has placed it on the frontier of Chinese civilization throughout much of History of China, Chinese history. The current name "Guang" means "expanse" and has been associated with the region since the creation of Guang Prefecture in 226 AD. It was given Administrative divisions of the Yuan dynasty, provincial level status during the Yuan dynasty, but ev ...

Sulcus (neuroanatomy)
In neuroanatomy, a sulcus (Latin: "furrow", pl. ''sulci'') is a depression or groove in the cerebral cortex. It surrounds a gyrus (pl. gyri), creating the characteristic folded appearance of the brain in humans and other mammals. The larger sulci are usually called fissures. Structure Sulci, the grooves, and gyri, the folds or ridges, make up the folded surface of the cerebral cortex. Larger or deeper sulci are termed fissures, and in many cases the two terms are interchangeable. The folded cortex creates a larger surface area for the brain in humans and other mammals. When looking at the human brain, two-thirds of the surface are hidden in the grooves. The sulci and fissures are both grooves in the cortex, but they are differentiated by size. A sulcus is a shallower groove that surrounds a gyrus. A fissure is a large furrow that divides the brain into lobes and also into the two hemispheres as the longitudinal fissure. Importance of expanded surface area As the surfac ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Stigma (botany)
The stigma () is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower. Description The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of , the cells of which are receptive to pollen. These may be restricted to the apex of the style or, especially in wind pollinated species, cover a wide surface. The stigma receives pollen and it is on the stigma that the pollen grain germinates. Often sticky, the stigma is adapted in various ways to catch and trap pollen with various hairs, flaps, or sculpturings. The pollen may be captured from the air (wind-borne pollen, anemophily), from visiting insects or other animals ( biotic pollination), or in rare cases from surrounding water (hydrophily). Stigma can vary from long and sle ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ovary (botany)
In the flowering plants, an ovary is a part of the female reproductive organ of the flower or gynoecium. Specifically, it is the part of the pistil which holds the ovule(s) and is located above or below or at the point of connection with the base of the petals and sepals. The pistil may be made up of one carpel or of several fused carpels (e.g. dicarpel or tricarpel), and therefore the ovary can contain part of one carpel or parts of several fused carpels. Above the ovary is the style and the stigma, which is where the pollen lands and germinates to grow down through the style to the ovary, and, for each individual pollen grain, to fertilize one individual ovule. Some wind pollinated flowers have much reduced and modified ovaries. Fruits A fruit is the mature, ripened ovary of a flower following double fertilization in an angiosperm. Because gymnosperms do not have an ovary but reproduce through double fertilization of unprotected ovules, they produce naked seeds that do not ...

Pistil
Gynoecium (; ) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of (one or more) ''pistils'' and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridia within the androecium. Flowers that bear a gynoecium but no stamens are calle ...

Dehiscence (botany)
Dehiscence is the splitting of a mature plant structure along a built-in line of weakness to release its contents. This is common among fruits, anthers and sporangia. Sometimes this involves the complete detachment of a part; structures that open in this way are said to be dehiscent. Structures that do not open in this way are called indehiscent, and rely on other mechanisms such as decay or predation to release the contents. A similar process to dehiscence occurs in some flower buds (e.g., ''Platycodon'', ''Fuchsia''), but this is rarely referred to as dehiscence unless wikt:circumscissile, circumscissile dehiscence is involved; anthesis is the usual term for the opening of flowers. Dehiscence may or may not involve the loss of a structure through the process of abscission. The lost structures are said to be wikt:caducous, caducous. Association with crop breeding Manipulation of dehiscence can improve crop yield since a Trait (biological), trait that causes seed dispersal i ...

Ligule
A ligule (from "strap", variant of ''lingula'', from ''lingua'' "tongue") is a thin outgrowth at the junction of leaf and leafstalk of many grasses (Poaceae) and sedges. A ligule is also a strap-shaped extension of the corolla, such as that of a ray floret in plants in the daisy family Asteraceae. Poaceae and Cyperaceae The ligule is part of the leaf that is found at the junction of the blade and sheath of the leaf. It may take several forms, but it is commonly some form of translucent membrane or a fringe of hairs. The membranous ligule can be very short 1–2 mm (Kentucky bluegrass, ''Poa pratensis'') to very long 10–20 mm (Johnson grass, ''Sorghum halepense''), it can also be smooth on the edge or very ragged. Some grasses do not have a ligule, for example barnyardgrass (''Echinochloa crus-galli''). A ligule can also be defined as a membrane-like tissue or row of delicate hairs typically found in grasses at the junction of the leaf sheath and blade. The ...
