Peltophorum Africanum
__NOTOC__ ''Peltophorum africanum'', the weeping wattle, is a semi-deciduous to deciduous flowering tree In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only ... growing to about 15 meters tall. It is native to Africa south of the equator. Their yellow flowers bloom on the ends of branches in upright, showy sprays. During spring time it may happen that water drips from the tree's branches, a phenomenon that is caused by the spittlebug '' Ptyelus grossus''. The immature stages of these spittlebugs congregate on the young shoots and derive their nourishment by sucking the tree's sap. While doing so they secrete pure water, which is the cause of the "weeping" effect. Common names Other common names include Rhodesian blackwood, African blackwood, Mosetlha, African wattle, African false watt ...

Otto Wilhelm Sonder
Otto Wilhelm Sonder (18 June 1812, Bad Oldesloe – 21 November 1881) was a German botanist and pharmacist. Life A native of Holstein, Sonder studied at Kiel University, where he sat pharmaceutical examinations in 1835, before becoming the proprietor of a pharmacy in Hamburg from 1841 to 1878. In 1846 he received an honorary doctorate from the University of Königsberg and was elected a member of the German National Academy of Sciences Leopoldina for his contribution to the field of botany. Herbarium From a young age, Sonder showed considerable interest and skill in Botany. He often embarked on botanical excursions in his local area early in the morning before heading to work at the pharmacy. Throughout his life, Sonder met and conversed with many eminent botanists of the era. He amassed an extensive botanical collection that contained hundreds of thousands of herbarium specimens representing all major plant groups and spanning all parts of the globe. The collection is partic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deciduous
In the fields of horticulture and botany, the term deciduous () means "falling off at maturity" and "tending to fall off", in reference to trees and shrubs that seasonally shed Leaf, leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit. The antonym of deciduous in the botanical sense is evergreen. Generally, the term "deciduous" means "the dropping of a part that is no longer needed or useful" and the "falling away after its purpose is finished". In plants, it is the result of natural processes. "Deciduous" has a similar meaning when referring to animal parts, such as deciduous antlers in deer, deciduous teeth (baby teeth) in some mammals (including humans); or decidua, the uterine lining that sheds off after birth. Botany In botany and horticulture, deciduous plants, including trees, shrubs and herbaceous perennials, are those that lose all of their Leaf, leaves for part of the year. This process is called abscission. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tree
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported cle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ptyelus Grossus
''Ptyelus grossus'' is an Auchenorrhynchan spittlebug in the family Aphrophoridae. Occurring from Southern Africa through to West Africa, the species is gregarious in its larval and nymph stages, feeding on a variety of plants, and producing protective shelters of acrid foam from their host plant's sap. Excreted in large quantities, the foam drips incessantly causing wet patches on the soil below. Adults have slate-grey wings, each wing with two white and yellow patches near the outer margin. The head is white, rounded with large dark eyes and small black and yellow marks on the forehead. Favoured trees are ''Tipuana'', ''Peltophorum'' and ''Lonchocarpus'', although its catholic diet includes species of ''Grevillea'', ''Rhus'', ''Acacia'', '' Vangueria'' and even ''Eucalyptus ''Eucalyptus'' () is a genus of more than 700 species of flowering plants in the family Myrtaceae. Most species of ''Eucalyptus'' are trees, often Mallee (habit), mallees, and a few are shrubs. Along with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Resources Of Tropical Africa
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants ( hornworts, liverworts, mosses, lycophytes, ferns, conifers and other ...

Peltophorum
''Peltophorum'' is a genus of 5–15 species of flowering plants in the family Fabaceae, subfamily Caesalpinioideae. The genus is native to certain tropical regions across the world, including northern South America, central and southern Africa, Indochina, southeastern China, Malesia, New Guinea, and northern Australia. The species are medium-sized to large trees growing up to 15–25 m tall, rarely 50 m.Germplasm Resources Information Network''Peltophorum''Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening''.
