Lomentum .
A loment (or lomentum) is a part of certain legume plants. It is a type of dehiscent fruit that breaks apart at the constrictions occurring between segments, so that each segment contains only one seed. It is a type of schizocarp. Tick trefoil (''Desmodium'') and sweet vetch (''Hedysarum'') are two genera that exhibit this fruit type, which is found particularly in the tribe Hedysareae of the family Fabaceae Fabaceae () or Leguminosae,International Code of Nomen ...

Hedysarum Hedysaroides 2005
''Hedysarum'' (sweetvetch) is a genus of the botanical family Fabaceae, consisting of about 200 species of annual or perennial herbs found in Asia, Europe, North Africa, and North America. Description Species within genus ''Hedysarum'' may be herbaceous plants or deciduous shrubs. They have odd-pinnate leaves, with entire leaflets (no notches or indentations). These leaves resemble the leaves of sweet peas. The stipules may be free or connate, and stipels (secondary stipules) are absent. The inflorescences are peduncled racemes or heads. Bracts are small, with bracteoles below the calyx, and calyx teeth subequal. The petals may be pink, purplish, yellow, or whitish. Vexillum is longer than the wings, with an obtuse keel longer or rarely shorter than the wings. Stamens are diadelphous, 9+1, and anthers uniform. Ovary is 2-8-ovuled. Fruit is a lomentum, with segments that are glabrous, pubescent, bristly, or spiny, and break into single-seeded sections on ripening. Uses ''Hed ...

Legume
Legumes are plants in the pea family Fabaceae (or Leguminosae), or the fruit or seeds of such plants. When used as a dry grain for human consumption, the seeds are also called pulses. Legumes are grown agriculturally, primarily for human consumption, but also as livestock forage and silage, and as soil-enhancing green manure. Legumes produce a botanically unique type of fruit – a simple fruit, simple Dry fruits, dry fruit that develops from a simple carpel and usually Dehiscence (botany) , dehisces (opens along a seam) on two sides. Most legumes have Symbiosis , symbiotic nitrogen fixation , nitrogen-fixing bacteria, Rhizobia, in structures called root nodules. Some of the fixed nitrogen becomes available to later crops, so legumes play a key role in crop rotation. Terminology The term ''pulse'', as used by the United Nations' Food and Agriculture Organization (FAO), is reserved for legume crops harvested solely for the dry seed. This excludes green beans and Pea , green ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, digestion by herbivores, 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 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 caducous. Association with crop breeding Manipulation of dehiscence can improve crop yield since a trait that causes seed dispersal is a disadvantage for fa ...

Schizocarp
A schizocarp is a dry fruit that, when mature, splits up into mericarps. There are different definitions: * Any Dry fruits, dry fruit composed of multiple carpels that separate. : Under this definition the mericarps can contain one or more seeds (the mericarps of ''Abutilon'' have two or more seeds) and each mericarp can be either: :* Indehiscent (remaining closed), such as in the carrot and other Umbelliferae or in members of the genus ''Malva'', or :* Dehiscent (splitting open to release the seed), for example members of the genus ''Geranium''. This is similar to what happens with a Capsule (fruit), capsule, but with an extra stage. (In ''Abutilon'', the mericarp is sometimes only partially dehiscent and does not release the seed.) * Any fruit that separates into indehiscent one-seeded segments, such as a loment, ''Malva'', ''Malvastrum'', and ''Sida (plant), Sida''.

Desmodium
''Desmodium'' is a genus of plants in the legume family Fabaceae, sometimes called tick-trefoil, tick clover, hitch hikers or beggar lice. There are dozens of species and the delimitation of the genus has shifted much over time. Species are distributed widely – from Quebec to northern Argentina in the Americas, across northern and southern tropical Africa, in the southern Arabian Peninsula, in Myanmar and Thailand, New Guinea, and northern and eastern Australia. Description These are mostly inconspicuous plants; few have bright or large flowers. Though some can become sizeable plants, most are herbs or small shrubs. Their fruit are loments, meaning each seed is dispersed individually enclosed in its segment. This makes them tenacious plants and some species are considered weeds in places. Uses Several ''Desmodium'' species release organic compounds, aerially and into the soil, which make them useful for agriculture: Allelopathic compounds are used there via push-pull tech ...

Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxa ranked above species are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

When the Papilionaceae are regarded as a family distinct from the remainder of the Leguminosae, the name Papilionaceae is conserved against Leguminosae."

Fruit Morphology
In botany, a fruit is the seed-bearing structure in flowering plants (angiosperms) that is formed from the ovary after flowering. Fruits are the means by which angiosperms disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and other animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; humans, and many other animals, have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language and culinary usage, ''fruit'' normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet (or sour) and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term ''fruit'' also in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
