Uvariastrum Insculptum
''Uvariastrum insculptum'' is a species of plant in the Annonaceae. It is native to Cameroon, Gabon, Ghana, Ivory Coast, Liberia, Nigeria, and the Republic of the Congo. Adolf Engler and Ludwig Diels, the botanists who first formally described the species using the basionym ''Uvaria insculpta'', named it after the secondary veins on its leaves which are distinctly sunken ( in Latin). Description ''Uvariastrum insculptum'' is a shrub or tree reaching 4–15 meters in height. The young, brown branches are hairy, but become hairless and brown-grey with maturity. Its narrowly elliptical to egg-shaped, papery to slightly leathery leaves are 6–14 by 2–4 centimeters. The leaves have rounded to slightly heart-shaped bases and tapering tips, with the tapering portion 1–2 centimeters long. The leaves are hairless to very sparsely hairy on their dark green upper and lower surfaces. The leaves have 8–12 pairs of secondary veins emanating from their midribs. The secondary veins con ...

Adolf Engler
Heinrich Gustav Adolf Engler (25 March 1844 – 10 October 1930) was a German botanist. He is notable for his work on alpha taxonomy, plant taxonomy and phytogeography, such as ''Die natürlichen Pflanzenfamilien'' (''The Natural Plant Families''), edited with Karl Anton Eugen Prantl, Karl A. E. von Prantl. Even now, his system of plant classification, the Engler system, is still used by many Herbarium, herbaria and is followed by writers of many manuals and Flora (plants), floras. It is still the only system that treats all 'plants' (in the wider sense, algae to flowering plants) in such depth. Engler published a prodigious number of taxonomic works. He used various artists to illustrate his books, notably Joseph Pohl (1864–1939), an illustrator who had served an apprenticeship as a wood-engraver. Pohl's skill drew Engler's attention, starting a collaboration of some 40 years. Pohl produced more than 33 000 drawings in 6 000 plates for ''Die naturlichen Pflanzenfamilien''. He ...

Pedicel (botany)
In botany, a pedicel is a stem that attaches a single flower to the inflorescence. Such inflorescences are described as ''pedicellate''. Description Pedicel refers to a structure connecting a single flower to its inflorescence. In the absence of a pedicel, the flowers are described as sessile. Pedicel is also applied to the stem of the infructescence. The word "pedicel" is derived from the Latin ''pediculus'', meaning "little foot". The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called a peduncle. A pedicel may be associated with a bract or bracts. In cultivation In Halloween types of pumpkin or squash plants, the shape of the pedicel has received particular attention because plant breeders are trying to optimize the size and shape of the pedicel for the best "lid" for a "jack-o'-lantern".

Flora Of The Republic Of The Congo
The wildlife of the Republic of the Congo is a mix of species of different kinds of organisms. There are 400 mammal species, 1,000 bird species and 10,000 plant species (3,000 of which are unique to the Republic of Congo) in the country. Many parts of the country are covered in tropical rainforest, although some of the southern areas have been cleared by logging. The wider Congo River Basin has earned a global reputation for the variety of wildlife found inside its forests. Rainforests A large portion of the Republic of Congo is tropical rainforest. The forest is split into several sections, the first being low lying branches of large evergreen trees. The next level contains smaller trees and plants. Under that level lies bushes and ferns. The floor of this region consists of mainly ferns, vines, and roots that twist and turn throughout different vegetation. Roughly 69% of the country consists of forest areas. The Congo Basin was designated as a UNESCO heritage site on July 1, 20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Nigeria
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. 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 Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Liberia
The wildlife of Liberia consists of the flora and fauna of the Republic of Liberia. This West African nation has a long Atlantic coastline and a range of habitat types, with a corresponding diversity of plants and animals. Liberia is considered a biodiversity hotspot and has more intact forests characteristic of the Upper Guinea Massif than do neighbouring countries. There are 2000 species of vascular plants (including 225 tree species), approximately 140 species of mammals, and over 600 species of birds. Geography The country lies close to the equator with a long coastline on the Atlantic Ocean. The terrain consists of flat or undulating coastal plains, which rise to a rolling plateau and low mountains in the northeast. A number of short rivers flow from northeast to southwest. The coastal area is characterised by swamps and mangrove forests, while inland the tropical forests give way to grassland on the drier plateau area. The climate is equatorial with some rain all year roun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flora Of Ghana
The wildlife of Ghana is composed of its biodiversity of flora and fauna. Biodiversity Fungi Ghana is home to a significant number of fungi species including: ''Aspergillus flavus''; ''Athelia rolfsii''; ''Auricularia auricula-judae''; ''Curvularia''; ''Fusarium oxysporum''; ''Fusarium solani'' f.sp. ''pisi''; '' Gibberella intricans''; ''Gibberella stilboides''; and ''Macrophomina phaseolina''. The true total number of fungal species occurring in Ghana is in the thousands and given the generally accepted estimate that only about 7 percent of all fungi worldwide have so far been discovered and that the amount of available information is still very small. Flora The flora of Ghana is diverse with both indigenous and introduced floral species considered in Ghana's floral diversity. A total of some 3,600 species of the major regional centres of endemism represent the three major taxonomic groups. Floral diversity is more pronounced among the angiosperms represented with well over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plants Described In 1916
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...

Ovule
In seed plants, the ovule is the structure that gives rise to and contains the female reproductive cells. It consists of three parts: the ''integument'', forming its outer layer, the ''nucellus'' (or remnant of the megasporangium), and the female gametophyte (formed from a haploid megaspore) in its center. The female gametophyte — specifically termed a ''megagametophyte''— is also called the ''embryo sac'' in angiosperms. The megagametophyte produces an egg cell for the purpose of fertilization. The ovule is a small structure present in the ovary. It is attached to the placenta by a stalk called a funicle. The funicle provides nourishment to the ovule. Location within the plant In flowering plants, the ovule is located inside the portion of the flower called the gynoecium. The ovary of the gynoecium produces one or more ovules and ultimately becomes the fruit wall. Ovules are attached to the placenta in the ovary through a stalk-like structure known as a ''funiculus'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gynoecium
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 called ''pi ...
