Paeonia Sterniana
''Paeonia sterniana'' is a perennial, herbaceous peony of approximately 45 cm high in cultivation, with white or sometimes pinkish flowers. It grows in the wild in southeastern Tibet. This peony is very rare in cultivation. It produces blue seeds in autumn. Its common name in Chinese is 白花芍药 (bai hua shao yao), which means "white peony".

Indumentum
In biology, an indumentum (Latin, literally: "garment") is a covering of trichomes (fine "hairs") on a plant Davis, Peter Hadland and Heywood, Vernon Hilton (1963) ''Principles of angiosperm taxonomy'' Van Nostrandpage, Princeton, New Jersey, page 154, or of bristles (rarely scales) of an insect. In plants, indumentum types include: *pubescent *hirsute *pilose *lanate *villous *tomentose *stellate *scabrous *scurfy The indumentum on plants can have a wide variety of functions, including as anchorage in climbing plants (e.g., '' Galium aparine''), in transpiration control, in water absorption ('' Tillandsia''), the reflection of solar radiation, increasing water-repellency (e.g., in the aquatic fern '' Salvinia''), in protection against insect predation, and in the trapping of insects ('' Drosera'', ''Nepenthes'', '' Stylosanthes''). The use of an indumentum on insects can also be pollen-related, as on bees, sensory like whiskers, or for varied other uses including adhesio ...

Paeonia Mairei
''Paeonia mairei'' is a species of peony, that is endemic to the mountains of central China. Its vernacular name in China is 美丽芍药 (mei li shao yao) meaning "beautiful peony". The plant may be between 45 and 100 cm high and has mostly rose-pink flowers of about 10 cm across, one on each stem. ''P. mairei'' blooms in early spring.

Endemic Flora Of Tibet
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peonies
The peony or paeony is a flowering plant in the genus ''Paeonia'' , the only genus in the family Paeoniaceae . Peonies are native to Asia, Europe and Western North America. Scientists differ on the number of species that can be distinguished, ranging from 25 to 40, although the current consensus is 33 known species. The relationships between the species need to be further clarified. Most are herbaceous perennial plants tall, but some are woody shrubs tall. They have compound, deeply lobed leaves and large, often fragrant flowers, in colors ranging from purple and pink to red, white or yellow, in late spring and early summer. The flowers have a short blooming season, usually only 7–10 days. Peonies are popular garden plants in temperate regions. Herbaceous peonies are also sold as cut flowers on a large scale, although generally only available in late spring and early summer.

Rock Garden
A rock garden, also known as a rockery and formerly as a rockwork, is a garden, or more often a part of a garden, with a landscaping framework of rocks, stones, and gravel, with planting appropriate to this setting. Usually these are small Alpine plants that need relatively little soil or water. Western rock gardens are often divided into alpine gardens, scree gardens on looser, smaller stones, and other rock gardens. Some rock gardens are planted around natural outcrops of rock, perhaps with some artificial landscaping, but most are entirely artificial, with both rocks and plants brought in. Some are designed and built to look like natural outcrops of bedrock. Stones are aligned to suggest a bedding plane, and plants are often used to conceal the joints between said stones. This type of rockery was popular in Victorian times and usually created by professional landscape architects. The same approach is sometimes used in commercial or modern-campus landscaping but can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yarlung Zangbo River
The Yarlung Tsangpo, also called Yarlung Zangbo () is the upper stream of the Brahmaputra River located in the Tibet Autonomous Region, China. It is the longest river of Tibet and the fifth longest in China. The upper section is also called Dangque Zangbu meaning "Horse River." Originating at Angsi Glacier in western Tibet, southeast of Mount Kailash and Lake Manasarovar, it later forms the South Tibet Valley and Yarlung Tsangpo Grand Canyon before passing into the state of Arunachal Pradesh, India. Downstream from Arunachal Pradesh the river becomes far wider and is called the Siang. After reaching Assam, the river is known as Brahmaputra. From Assam, the river enters Bangladesh at Ramnabazar. From there until about 200 years ago it used to flow eastward and joined the Meghna River near Bhairab Upazila. This old channel has been gradually dying. At present the main channel of the river is called Jamuna River, which flows southward to meet the Ganges, which in Bangladesh is ca ...

Plant Collecting
Plant collecting is the acquisition of plant specimens for the purposes of research, cultivation, or as a hobby. Plant specimens may be kept alive, but are more commonly dried and pressed to preserve the quality of the specimen. Plant collecting is an ancient practice with records of a Chinese botanist collecting roses over 5000 years ago. Herbaria are collections of preserved plants samples and their associated data for scientific purposes. The largest herbarium in the world exist at the Muséum National d'Histoire Naturelle, in Paris, France. Plant samples in herbaria typically include a reference sheet with information about the plant and details of collection. This detailed and organized system of filing provides horticulturist and other researchers alike with a way to find information about a certain plant, and a way to add new information to an existing plant sample file. The collection of live plant specimens from the wild, sometimes referred to as plant hunting, is an ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
