Photinia Serrulata
''Photinia serratifolia'' (syn. ''Photinia serrulata''), commonly called Taiwanese photinia or Chinese photinia is a flowering shrub or tree in the flowering plants family Rosaceae, found in mixed forests of China, Taiwan, Japan, the Philippines, Indonesia, and India. Description The tree is evergreen, with white flowers emerging in Spring accompanied by red-colored leaves, and red fruits growing in Autumn. It grows typically , sometimes up to , tall.

René Louiche Desfontaines
René Louiche Desfontaines (14 February 1750 – 16 November 1833) was a French botanist. Desfontaines was born near Tremblay, Ille-et-Vilaine , Tremblay in Brittany. He attended the Collège de Rennes and in 1773 went to Paris to study medicine. His interest in botany originated from lectures at the Jardin des Plantes given by Louis Guillaume Lemonnier. He excelled in his new interest and was elected to the French Academy of Sciences in 1783. He was also a member of the Académie Nationale de Médecine. Desfontaines spent two years in Tunisia and Algeria, returning with a large collection of plants. He wrote ''Flora Atlantica'' (1798–1799, 2 vols), which included 300 genera new to science. In addition, he worked also on ornithology, and presented the findings of his expeditions to Africa for one of the ''Memoires de L'Académie Royale des Sciences''. Although the ''Mémoire'' corresponds to the year 1787, it was not published until 1789 by L'Imprimerie Royal as part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thrush (bird)
The thrushes are a passerine bird family, Turdidae, with a worldwide distribution. The family was once much larger before biologists reclassified the former subfamily Saxicolinae, which includes the chats and European robins, as Old World flycatchers. Thrushes are small to medium-sized ground living birds that feed on insects, other invertebrates and fruit. Some unrelated species around the world have been named after thrushes due to their similarity to birds in this family. Characteristics Thrushes are plump, soft-plumaged, small to medium-sized birds, inhabiting wooded areas, and often feeding on the ground. The smallest thrush may be the forest rock thrush, at and . However, the shortwings, which have ambiguous alliances with both thrushes and Old World flycatchers, can be even smaller. The lesser shortwing averages . The largest thrush is the Great thrush at and , though the commonly recognized Blue whistling-thrush is an Old world flycatcher. The Amami thrush might, howe ...

Trees Of Japan
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 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of India (region)
The flora of India is one of the richest in the world due to the wide range of climate, topology and habitat in the country. There are estimated to be over 18,000 species of flowering plants in India, which constitute some 6-7 percent of the total plant species in the world. India is home to more than 50,000 species of plants, including a variety of endemics. The use of plants as a source of medicines has been an integral part of life in India from the earliest times. There are more than 3000 Indian plant species officially documented as possessing into eight main floristic regions : Western Himalayas, Eastern Himalayas, Assam, Indus plain, Ganges plain, the Deccan, Malabar and the Andaman Islands. Forests and wildlife resources In 1992, around 7,43,534 km2 of land in the country was under forests of which 92 percent belongs to the government. Only 22.7 percent is forested compared to the recommended 33 percent of the National Forest Policy Resolution 1952. The majo ...

Photinia
''Photinia'' () is a genus of about 30 species of small trees and large shrubs, but the taxonomy has recently varied greatly, with the genera ''Heteromeles'', ''Stranvaesia'' and ''Aronia'' sometimes included in ''Photinia''. They are a part of the rose family (Rosaceae) and related to the apple. The botanical genus name derives from the Greek word photeinos for shiny and refers to the often glossy leaves. Most species are evergreen, but deciduous species also occur. The small apple-shaped fruit has a size of 4 to 12 mm and forms in large quantities. They ripen in the fall and often remain hanging on the bush until well into the winter. The fruits are used as food by birds, which excrete the seeds with their droppings and thereby distribute the plant. The natural range of these species is restricted to warm temperate Asia, from the Himalaya east to Japan and south to India and Thailand. They have, however, been widely cultivated throughout the world as ornamentals for their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Greening
Greening is the process of transforming living environments, and also artifacts such as a space, a lifestyle or a brand image, into a more environmentally friendly version (i.e. 'greening your home' or 'greening your office'). The act of greening generally involves incorporating more environmentally friendly systems into one's environment, such as the home, work place, and general lifestyle. Greening is also a general term for the appropriate selection and planting of plants on, in, or next to buildings and in public parks. The goal of greening is usually a combination of environmental benefits and improving the visual design of surfaces, for example, a green wall or green roof, as well as the creation of green spaces. This usually requires technical measures such as earthworks or supporting climbing plants. Furthermore, permanent care and irrigation is usually necessary to maintain the greened environment. In some areas there are normative requirements for the planning and ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Obovate
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
