Parrotiopsis Jacquemontiana
''Parrotiopsis jacquemontiana'' is a species of deciduous shrub or small tree in the witch hazel family, native to the western Himalayas, particularly Kashmir, Murree, Hazara, the Swat District, and Kurram, at altitudes from 1200 to 2800 meters. It grows to in height by wide, with hermaphrodite flowers borne in dense tufts of stamen The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filame ...s from April to June.

Joseph Decaisne
Joseph Decaisne (7 March 1807 – 8 January 1882) was a French botanist and agronomist. He became an ''aide-naturaliste'' to Adrien-Henri de Jussieu (1797-1853), who served as the chair of rural botany. It was during this time that he began to study plants brought back by various travelers like those of Victor Jacquemont (1801-1832) from Asia. Decaisne used applied research, most notably on the agronomy of the Rubia tinctorum, madder, the Yam (vegetable), yam and the ramie. He was also interested in algae. Biography Although born in Brussels, Belgium, he exercised his activity exclusively in Paris. He entered in 1824 as a gardener at the ''Muséum national d'histoire naturelle'' (French museum of natural history) and became, in 1832, head of the ''carré des semis'' section. He also worked at the ''Jardin des Plantes'' and collaborated with Asa Gray. In 1847 he chaired Statistical Agriculture department in the College de France. In 1850, Decaisne followed Charles-François Brisse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alfred Rehder
Alfred Rehder (4 September 1863 in Waldenburg, Saxony – 25 July 1949 in Jamaica Plain, Massachusetts) was a German-American botanical taxonomist and dendrologist who worked at the Arnold Arboretum of Harvard University. He is generally regarded as the foremost dendrologist of his generation. Life Georg Alfred Rehder was born in the castle of Waldenburg to Thekla née Schmidt (1839–1897) and Paul Julius Rehder (1833–1917), the superintendent of parks and gardens of the principality of Schönburg-Waldenburg. Through his father, Rehder was introduced to the gardening profession. On his mother's side of the family, Rehder was likely descended from Henry, Duke of Anhalt-Köthen (1778–1847). Rehder broke off his attendance at the gymnasium in Zwickau in 1881 and did not pursue university studies, instead working for three years as an apprentice under the tutelage of his father. His professional career began in 1884 at the Berlin Botanical Garden. Here he was able to a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about five y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hamamelidaceae
Hamamelidaceae, commonly referred to as the witch-hazel family, is a family of flowering plants in the order Saxifragales. The clade consists of shrubs and small trees positioned within the woody clade of the core Saxifragales. An earlier system, the Cronquist system, recognized Hamamelidaceae in the Hamamelidales order. Description The Hamamelidaceae are distinguishable from other families in the Saxifragales due to the range of floral characteristics that are generally uniform though all genera. Uniform characteristics include stipules borne on stems with leaves often 2-ranked. Genera usually have a two carpel gynoecium, although some species show variation. Other characteristics include a multicellular stigma, with shallow papillae or ridges. Anthers Anther structure and the modes of opening are considered to be one of the most important features in the systematics and evolution of hamamelids. The anthers in Hamamelids are on average shorter than in other families in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Himalayas
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 planet's highest peaks, including the very highest, Mount Everest. Over 100 peaks exceeding in elevation lie in the Himalayas. By contrast, the highest peak outside Asia (Aconcagua, in the Andes) is tall. The Himalayas abut or cross five countries: Bhutan, India, Nepal, China, and Pakistan. 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.

Kashmir
Kashmir () is the northernmost geographical region of the Indian subcontinent. Until the mid-19th century, the term "Kashmir" denoted only the Kashmir Valley between the Great Himalayas and the Pir Panjal Range. Today, the term encompasses a larger area that includes the Indian-administered territories of Jammu and Kashmir and Ladakh, the Pakistani-administered territories of Azad Kashmir and Gilgit-Baltistan, and the Chinese-administered territories of Aksai Chin and the Trans-Karakoram Tract. Quote: "Kashmir, region of the northwestern Indian subcontinent. It is bounded by the Uygur Autonomous Region of Xinjiang to the northeast and the Tibet Autonomous Region to the east (both parts of China), by the Indian states of Himachal Pradesh and Punjab to the south, by Pakistan to the west, and by Afghanistan to the northwest. The northern and western portions are administered by Pakistan and comprise three areas: Azad Kashmir, Gilgit, and Baltistan, ... The southern and so ...

Murree
Murree ( Punjabi, Urdu: مری) is a mountain resort city, located in the Galyat region of the Pir Panjal Range, within the Muree District of Punjab, Pakistan. It forms the outskirts of the Islamabad-Rawalpindi metropolitan area, and is about northeast of Islamabad. It has average altitude of . The British built this town during their rule to escape the scorching heat in the plains of Punjab during the summer. Construction of the town was started in 1851 on the hill of Murree as a sanatorium for British troops. The permanent town of Murree was constructed in 1853 and the church was consecrated shortly thereafter. One main road was established, commonly referred to even in modern times, as the mall. Murree was the summer headquarters of the colonial Punjab Government until 1876 when it was moved to Shimla. Murree became a popular tourist station for British citizens of the British Raj. Several prominent Britons were born here including Bruce Bairnsfather, Francis Younghusband, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Swat District
Swat District (, ps, سوات ولسوالۍ, ) is a district in the Malakand Division of Khyber Pakhtunkhwa, Pakistan. With a population of 2,309,570 per the 2017 national census, Swat is the 15th-largest district of Khyber Pakhtunkhwa province. Swat District is centered on the Valley of Swat, usually referred to simply as Swat, which is a natural geographic region surrounding the Swat River. The valley was a major centre of early Buddhism under the ancient kingdom of Gandhara, and was a major centre of Gandharan Buddhism, with pockets of Buddhism persisting in the valley until the 10th century, after which the area became largely Muslim. Until 1969, Swat was part of the Yusafzai State of Swat, a self-governing princely state that was inherited by Pakistan following its independence from British rule. The region was seized by the Tehrik-i-Taliban in late-2007 until Pakistani control was re-established in mid-2009. The average elevation of Swat is , resulting in a consid ...

Hermaphrodite
In reproductive biology, a hermaphrodite () is an organism that has both kinds of reproductive organs and can produce both gametes associated with male and female sexes. Many Taxonomy (biology), taxonomic groups of animals (mostly invertebrates) do not have separate sexes. In these groups, hermaphroditism is a normal condition, enabling a form of sexual reproduction in which either partner can act as the female or male. For example, the great majority of tunicata, tunicates, pulmonate molluscs, opisthobranch, earthworms, and slugs are hermaphrodites. Hermaphroditism is also found in some fish species and to a lesser degree in other vertebrates. Most plants are also hermaphrodites. Animal species having different sexes, male and female, are called Gonochorism, gonochoric, which is the opposite of hermaphrodite. There are also species where hermaphrodites exist alongside males (called androdioecy) or alongside females (called gynodioecy), or all three exist in the same species ( ...
