Pterolobium Stellatum
''Pterolobium stellatum'' (Latin: ''stellatum'', starry or star-like, suggesting the radial arrangement of inflorescences), the redwing, is a perennial flowering plant in the legume family, Fabaceae. Range and habitat It is the only member of the genus to occur in Africa, where it has an extensive but easterly range, from northern South Africa to Sudan, Ethiopia and on to Yemen in the Arabian Peninsula. They are found on rocky slopes and kopjes, riparian floodplains, or along forest margins. Description Young plants are hairy on the stems and leaves, while mature plants have scrambling rope-like branches that are armed with recurved thorns or conical knobs. The alternate and bipinnately compound leaves consist of 5 to 13 paired primary leaflets (pinnae), and 7 to 16 paired leaflets per pinna. The underside of the rachis carries pairs of recurved thorns, or solitary straight ones. They produce cream-coloured inflorescences composed of dense compound racemes (panicles). These ar ...

Peter Forsskål
Peter Forsskål, sometimes spelled Pehr Forsskål, Peter Forskaol, Petrus Forskål or Pehr Forsskåhl (11 January 1732 – 11 July 1763) was a Swedish-speaking Finnish explorer, orientalist, naturalist, and an apostle of Carl Linnaeus. Early life Forsskål was born in Helsinki, now in Finland but then a part of Sweden, where his father, Finnish priest , was serving as a Lutheran clergyman, but the family migrated to Sweden in 1741 when the father was appointed to the parish of Tegelsmora in Uppland and the archdiocese of Uppsala. As was common at the time, he enrolled at Uppsala University at a young age in 1742, but returned home for some time and, after studies on his own, rematriculated in Uppsala in 1751, where he completed a theological degree the same year. Linnaeus's disciple In Uppsala Forsskål was one of the students of Linnaeus, but apparently also studied with the orientalist Carl Aurivillius, whose contacts with the Göttingen orientalist Johann David Michae ...

Raceme
A raceme ( or ) or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard (genus '' Brassica'') and radish (genus '' Raphanus'') plants. Definition A ''raceme'' or ''racemoid'' is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called '' pedicels'') along its axis. In botany, an ''axis'' means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. the species '' Cimicifuga racemosa''. A comp ...

Flora Of East Tropical Africa
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurma ...

Pterolobium
The genus, ''Pterolobium'' (from Gr. πτερόν ''pterón'', meaning "wing", and λόβιον ''lóbion'', meaning "pod" or "capsule", alluding to the winged fruit), consists of 10 species of perennial flowering plants in the family Fabaceae, subfamily Caesalpinioideae and tribe Caesalpinieae. They are sometimes called redwings and are native to the tropical to subtropical climes of Africa and Asia, including Indonesia and the Philippines. They are large scrambling or climbing shrubs that grow in riverside thickets, on rocky slopes or at forest margins. They bear colourful samara fruit, and have pairs of thorns below the rachis of their bipinnate leaves. Species ''Pterolobium'' comprises the following species: * '' Pterolobium borneense'' Merrill * '' Pterolobium densiflorum'' Prain * ''Pterolobium hexapetalum'' (Roth) Santapau & Wagh ― camp siege * '' Pterolobium integrum'' Craib * '' Pterolobium macropterum'' Kurz (synonym ''P. sinense'') * '' Pterolobium membranulaceum ...

Tigrinya
(; also spelled Tigrigna) is an Ethio-Semitic language commonly spoken Eritrea and in northern Ethiopia's Tigray Region by the Tigrinya and Tigrayan peoples. It is also spoken by the global diaspora of these regions. History and literature Although it differs markedly from the Geʽez (Classical Ethiopic) language, for instance in having phrasal verbs, and in using a word order that places the main verb last instead of first in the sentence—there is a strong influence of Geʽez on Tigrinya literature, especially with terms relating to Christian life, Biblical names, and so on. Ge'ez, because of its status in Ethiopian culture, and possibly also its simple structure, acted as a literary medium until relatively recent times. The earliest written example of Tigrinya is a text of local laws found in the district of Logosarda, Debub Region in Southern Eritrea, which dates from the 13th century. In Eritrea, during British administration, the Ministry of Information put out a w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amharic
Amharic ( or ; (Amharic: ), ', ) is an Ethiopian Semitic languages, Ethiopian Semitic language, which is a subgrouping within the Semitic languages, Semitic branch of the Afroasiatic languages. It is spoken as a first language by the Amhara people, Amharas, and also serves as a lingua franca for all other populations residing in major cities and towns of Ethiopia. The language serves as the official working language of the Ethiopian federal government, and is also the official or working language of several of Regions of Ethiopia, Ethiopia's federal regions. It has over 31,800,000 mother-tongue speakers, with more than 25,100,000 second language speakers. Amharic is the most widely spoken language in Ethiopia, and the second most spoken Languages of Ethiopia, mother-tongue in Ethiopia (after Oromo language, Oromo). Amharic is also the second largest Semitic language in the world (after Arabic). Amharic is written left-to-right using a system that grew out of the Geʽez script. ...

Samara (fruit)
A samara (, ) is a winged achene, a type of fruit in which a flattened wing of fibrous, papery tissue develops from the ovary wall. A samara is a simple dry fruit, and is indehiscent (not opening along a seam). The shape of a samara enables the wind to carry the seed farther away from the tree than regular seeds would go, and is thus a form of anemochory. In some cases the seed is in the centre of the wing, as in the elms (genus ''Ulmus''), the hoptree ('' Ptelea trifoliata''), and the bushwillows (genus '' Combretum''). In other cases the seed is on one side, with the wing extending to the other side, making the seed autorotate as it falls, as in the maples (genus ''Acer'') and ash trees (genus '' Fraxinus''). There are also single-wing samara such as mahogany (genus Swietenia) which have a shape that enables fluttering. Some species that normally produce paired samaras, such as '' Acer pseudoplatanus'', can also produce them in groups of three or four. File:TripleSy ...

Rachis
In biology, a rachis (from the grc, ῥάχις [], "backbone, spine") is a main axis or "shaft". In zoology and microbiology In vertebrates, ''rachis'' can refer to the series of articulated vertebrae, which encase the spinal cord. In this case the ''rachis'' usually forms the supporting axis of the body and is then called the spine or vertebral column. ''Rachis'' can also mean the central shaft of pennaceous feathers. In the gonad of the invertebrate nematode ''Caenorhabditis elegans'', a rachis is the central cell-free core or axis of the gonadal arm of both adult males and hermaphrodites where the germ cells have achieved pachytene and are attached to the walls of the gonadal tube. The rachis is filled with cytoplasm. In botany In plants, a rachis is the main axis of a compound structure. It can be the main stem of a compound leaf, such as in ''Acacia'' or ferns, or the main, flower-bearing portion of an inflorescence above a supporting peduncle. Where it subdivide ...
