Przewalskia
''Przewalskia'' is a genus of flowering plants belonging to the family Solanaceae. Its native range is western and central China, Tibet to eastern Himalaya. The genus name of ''Przewalskia'' is in honour of Nikolay Przhevalsky Nikolay Mikhaylovich Przhevalsky (or Prjevalsky;; , . – ) was a Russian geographer and a renowned explorer of Central and East Asia.

Hyoscyameae
Hyoscyameae is an Old World Tribe (biology), tribe of the subfamily Solanoideae of the flowering plant family Solanaceae. It comprises seven genera: ''Anisodus'', ''Atropa'', ''Atropanthe'', ''Hyoscyamus'', ''Physochlaina'', ''Przewalskia'' and ''Scopolia''. The genera ''Atropanthe'' and ''Przewalskia'' are monotypic, the first being endemic to China and the second to Tibet. All seven genera of the tribe are poisonous and have a long tradition of use as medicinal plants, being rich in tropane alkaloids with anticholinergic properties. Furthermore, the genera ''Atropa'', ''Hyoscyamus'', ''Scopolia'' and ''Physochlaina'' have furnished entheogens - the first three in the historical context of European witchcraft and, more specifically, of the flying ointments employed in such practices, while the similar chemistry of the remaining genera points to the potential for entheogenic use. Six of the genera have dry, pyxidial fruits i.e. capsules dehiscing by an Operculum (botany), operculu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nikolay Przhevalsky
Nikolay Mikhaylovich Przhevalsky (or Prjevalsky;; , . – ) was a Russian geographer and a renowned explorer of Central and East Asia. Although he never reached his ultimate goal, the city of Lhasa in Tibet, he still travelled through regions then unknown to Westerners, such as northern Tibet (modern Tibet Autonomous Region), Amdo (now Qinghai) and Dzungaria (now northern Xinjiang). He contributed substantially to European knowledge of Central Asian geography. Przhevalsky described several species previously unknown to European science, such as Przewalski's horse, Przewalski's gazelle, and the wild Bactrian camel, all of which are now endangered. He was also a mentor of the explorer Pyotr Kozlov. Biography Przhevalsky was born in the Kimborovo family estate (in the Smolensky Uyezd of the Smolensk Governorate of the Russian Empire) which belonged to his grandfather from his mother's side, a Russian nobleman Aleksei Stepanovich Karetnikov, and his wife Ksenia Davydovna Karet ...

Solanaceae
Solanaceae (), commonly known as the nightshades, is a family of flowering plants in the order Solanales. It contains approximately 2,700 species, several of which are used as agricultural crops, medicinal plants, and ornamental plants. Many members of the family have high alkaloid contents, making some highly toxic, but many—such as tomatoes, potatoes, eggplants, and peppers—are commonly used in food. Originating in South America, Solanaceae now inhabits every continent on Earth except Antarctica. After the K—Pg extinction event they rapidly diversified and have adapted to live in deserts, tundras, rainforests, plains, and highlands, and taken on wide range of forms including trees, vines, shrubs, and epiphytes. Nearly 80% of all nightshades are included in the subfamily Solanoideae, most of which are members of the type genus ''Solanum''. Most taxonomists recognize six other subfamilies: Cestroideae, Goetzeoideae, Nicotianoideae, Petunioideae, Schizanthoideae, an ...

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] |
Tibet
Tibet (; ''Böd''; ), or Greater Tibet, is a region in the western part of East Asia, covering much of the Tibetan Plateau and spanning about . It is the homeland of the Tibetan people. Also resident on the plateau are other ethnic groups such as Mongols, Monpa people, Monpa, Tamang people, Tamang, Qiang people, Qiang, Sherpa people, Sherpa, Lhoba people, Lhoba, and since the 20th century Han Chinese and Hui people, Hui. Tibet is the highest region on Earth, with an average elevation of . Located in the Himalayas, the highest elevation in Tibet is Mount Everest, Earth's highest mountain, rising above sea level. The Tibetan Empire emerged in the 7th century. At its height in the 9th century, the Tibetan Empire extended far beyond the Tibetan Plateau, from the Tarim Basin and Pamirs in the west, to Yunnan and Bengal in the southeast. It then divided into a variety of territories. The bulk of western and central Tibet (Ü-Tsang) was often at least nominally unified under a ser ...

Himalaya
The Himalayas, or Himalaya ( ), is a mountain range in Asia, separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has some of the Earth's highest peaks, including the highest, Mount Everest. More than 100 peaks exceeding elevations of above sea level lie in the Himalayas. The Himalayas abut on or cross territories of six countries: Nepal, China, Pakistan, Bhutan, India and Afghanistan. The sovereignty of the range in the Kashmir region is disputed among India, Pakistan, and China. The Himalayan range is bordered on the northwest by the Karakoram and Hindu Kush ranges, on the north by the Tibetan Plateau, and on the south by the Indo-Gangetic Plain. Some of the world's major rivers, the Indus, the Ganges, and the Tsangpo– Brahmaputra, rise in the vicinity of the Himalayas, and their combined drainage basin is home to some 600 million people; 53 million people live in the Himalayas. The Himalayas have profoundly shaped the cultures of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1882
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 gymnosperm ...

Flora Of North-Central China
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. 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 ...
