Dombeya Rotundifolia
''Dombeya rotundifolia'', the dikbas or "South African wild pear" (it is not related to pear trees), is a small deciduous tree with dark grey to blackish deeply fissured bark, found in Southern Africa and northwards to central and eastern tropical Africa. Formerly placed in the Sterculiaceae, that artificial group has now been abandoned by most authors and the plants are part of an enlarged Malvaceae. ''Dombeya rotundifolia'' was originally described by Hochstetter. The ''D. rotundifolia'' of Bojer is now '' Dombeya spectabilis''. Description Trees are normally 5–6 m tall with a single well-defined trunk, growing on deep soils, river banks and rocky places. Leaves and flower buds are densely covered in stellate hairs. One of the first species to flower in spring, often with ''Erythrina lysistemon''. Flowers are abundant and sweet-scented, usually white but occasionally pale pink. Flowers (15–20 mm diameter) inconspicuous round fruits form at the centre of the bro ...

Dombeya Autumnalis
''Dombeya'' is a flowering plant genus. Traditionally included in the family Sterculiaceae, it is included in the expanded Malvaceae in the APG and most subsequent systematics. These plants are known by a number of vernacular names which sometimes, misleadingly, allude to the superficial similarity of flowering ''Dombeya'' to pears or hydrangeas (which are unrelated). Therefore, the genus as a whole is often simply called dombeyas. The generic name commemorates Joseph Dombey (1742–1794), a French botanist and explorer in South America, involved in the notorious "Dombey affair", embroiling scientists and governments of France, Spain, and Britain for more than two years. Distribution These plants grow chiefly throughout Africa and Madagascar. Madagascar has the majority of species, with approximately 175 native species. 19 are found on the African mainland, with one, ''Dombeya torrida'', also extending into the southwestern Arabian Peninsula.Skema, Cynthia. “Toward a New Circ ...

Drought-tolerant Trees
Drought tolerance is the ability to which a plant maintains its biomass production during arid or drought conditions. Some plants are naturally adapted to dry conditions'','' surviving with protection mechanisms such as desiccation tolerance, detoxification, or repair of xylem embolism. Other plants, specifically crops like corn, wheat, and rice, have become increasingly tolerant to drought with new varieties created via genetic engineering. The plants behind drought tolerance are complex and involve many pathways which allows plants to respond to specific sets of conditions at any given time. Some of these interactions include stomatal conductance, carotenoid degradation and anthocyanin accumulation, the intervention of osmoprotectants (such as sucrose, glycine, and proline), ROS-scavenging enzymes. The molecular control of drought tolerance is also very complex and is influenced other factors such as environment and the developmental stage of the plant. This control consists ...

Ornamental Trees
Ornamental plants or garden plants are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost any types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents. aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and foliage plants. The cultivation of ornamental plants comes under floriculture and tree nurseries, which is a ma ...

Flora Of Mozambique
The wildlife of Mozambique consists of the flora and fauna of this country in southeastern Africa. Mozambique has a range of different habitat types and an ecologically rich and diverse wildlife. This includes 236 species of mammal, 740 species of bird and 5,692 species of vascular plant. The Maputaland-Pondoland-Albany hotspot, with significantly high levels of biodiversity, stretches from the southern tip of Mozambique into northeastern South Africa. Geography Mozambique is located on the southeast coast of Africa. It is bounded by Eswatini to the south, South Africa to the south and southwest, Zimbabwe to the west, Zambia and Malawi to the northwest, Tanzania to the north and the Indian Ocean to the east. Mozambique lies between latitudes 10° and 27°S, and longitudes 30° and 41°E. The country is divided into two topographical regions by the Zambezi River. To the north of the Zambezi, the narrow coastal strip gives way to inland hills and low plateaus. Rugged highland ...

Trees Of South Africa
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, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a 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 reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically ...

List Of Southern African Indigenous Trees
This is a list of Southern African trees, shrubs, suffrutices, geoxyles and lianes, and is intended to cover Angola, Botswana, Lesotho, Malawi, Mozambique, Namibia, South Africa, Swaziland, Zambia and Zimbabwe. The notion of 'indigenous' is of necessity a blurred concept, and is clearly a function of both time and political boundaries. The global distribution of plants useful to humans, or inadvertently transported by them, is closely linked to a mapping of their journeys and settlements, and the movement of species in prehistoric times must be inferred from archaeological and palaeontological remains, centers of diversity, DNA and other sources.

Scale Insect
Scale insects are small insects of the order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the infraorder Coccomorpha which is considered a more convenient grouping than the superfamily Coccoidea due to taxonomic uncertainties. Adult females typically have soft bodies and no limbs, and are concealed underneath domed scales, extruding quantities of wax for protection. Some species are hermaphroditic, with a combined ovotestis instead of separate ovaries and testes. Males, in the species where they occur, have legs and sometimes wings, and resemble small flies. Scale insects are herbivores, piercing plant tissues with their mouthparts and remaining in one place, feeding on sap. The excess fluid they imbibe is secreted as honeydew on which sooty mold tends to grow. The insects often have a mutualistic relationship with ants, which feed on the honeydew and protect them from predators. There are about 8,000 descr ...

Fishmeal
Fish meal is a commercial product made from whole wild-caught fish, bycatch and fish by-products to feed farm animals, e.g., pigs, poultry, and farmed fish.R. D. Miles and F. A. Chapman.FA122: The Benefits of Fish Meal in Aquaculture DietsFisheries and Aquatic Sciences Department, UF/IFAS Extension. Original publication date November 2005. Reviewed January 2015. Because it is calorically dense and cheap to produce, fishmeal has played a critical role in the growth of factory farms and the number of farm animals it is possible to breed and feed. Fishmeal takes the form of powder or cake. This form is obtained by drying the fish or fish trimmings, and then grinding it. If the fish used is a fatty fish it is first pressed to extract most of the fish oil.M. L. Windsor for the UK Department of Trade and Industry, Torry Research StationFish meal.

Beekeeper
A beekeeper is a person who keeps honey bees. Beekeepers are also called honey farmers, apiarists, or less commonly, apiculturists (both from the Latin '' apis'', bee; cf. apiary). The term beekeeper refers to a person who keeps honey bees in beehives, boxes, or other receptacles. The beekeeper does not control the creatures. The beekeeper owns the hives or boxes and associated equipment. The bees are free to forage or leave (swarm) as they desire. Bees usually return to the beekeeper's hive as the hive presents a clean, dark, sheltered home. Purposes of beekeeping Value of honey bees Honey bees produce commodities such as honey, beeswax, pollen, propolis, and royal jelly. Some beekeepers also raise queens and other bees to sell to other farmers, and to satisfy scientific curiosity. Beekeepers also use honeybees to provide pollination services to fruit and vegetable growers. Many people keep bees as a hobby. Others do it for income either as a sideline to other work or as a ...
