Roscoea Cautleyoides
''Roscoea cautleyoides'' is a perennial herbaceous plant occurring in the Sichuan and Yunnan provinces of China. The scientific name is also spelt ''Roscoea cautleoides'' (see below). Most members of the ginger family (Zingiberaceae), to which it belongs, are tropical, but ''R. cautleyoides'', like other species of ''Roscoea'', grows in much colder mountainous regions. It is sometimes grown as an ornamental plant in gardens. Description ''Roscoea cautleyoides'' is a perennial herbaceous plant. Like all members of the genus ''Roscoea'', it dies back each year to a short vertical rhizome, to which are attached the tuberous roots. When growth begins again, "pseudostems" are produced: structures which resemble stems but are actually formed from the tightly wrapped bases (sheaths) of its leaves. ''R. cautleyoides'' is usually 15–40 cm tall (occasionally up to 60 cm), with three or four leaves. Each leaf has a small ligule, extending to about 1 mm. The blade of the le ...

François Gagnepain
François Gagnepain (23 September 1866 – 25 January 1952) was a French botanist. The standard botanical author abbreviation Gagnep. is applied to plants described by Gagnepain. With Achille Eugène Finet, he named a number of species within the botanical family Annonaceae. The genus ''Gagnepainia'' (family Zingiberaceae) was named in his honor by Karl Moritz Schumann. The French Academy of Sciences awarded Gagnepain the ''Prix de Coincy'' for the year 1907.

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 filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.

Roscoea Cautleyoides Early Purple
''Roscoea'' is a genus of perennial plants of the family Zingiberaceae (the ginger family). Most members of the family are tropical, whereas ''Roscoea'' species are native to mountainous regions of the Himalayas, China and its southern neighbours. ''Roscoea'' flowers superficially resemble orchids, although they are not related. The flowers of ''Roscoea'' have a complicated structure, in which some of the showy coloured parts are not formed by petals, but by staminodes, sterile stamens which have evolved to become like petals. Some species are grown as ornamental plants in gardens. Description ''Roscoea'' is found from Kashmir through the Himalayas to Vietnam, extending northwards into China. There are up to 22 recognized species, of which 8 are endemic to China. Typically they grow in grassland, in screes or on the edges of deciduous woodland at heights of , coming into growth at the start of the monsoon season. Species of ''Roscoea'' are small perennial herbaceous plants. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roscoea Wardii
''Roscoea wardii'' is a perennial herbaceous plant occurring from eastern Arunachal Pradesh in India to western Yunnan in China. Most members of the ginger family (Zingiberaceae), to which it belongs, are tropical, but like other species of ''Roscoea'', ''R. wardii'' grows in much colder mountainous regions. Description ''Roscoea wardii'' is a perennial herbaceous plant. Like all members of the genus ''Roscoea'', it grows from a short rhizome, to which the tuberous roots are attached. When growth begins again, "pseudostems" are produced: structures which resemble stems but are actually formed from the tightly wrapped bases (sheaths) of its leaves. ''R. wardii'' reaches a height of 32 cm. There are three to five bladeless sheathing leaves with pink veins and two to three full leaves, 7–8 cm long by 1.7–4.5 cm wide. At the junction of the blade and sheath there are small transparent structures (ligules), 1–2 mm high. The stem ( peduncle) of the ...

Brahmaputra River
The Brahmaputra is a trans-boundary river which flows through Tibet, northeast India, and Bangladesh. It is also known as the Yarlung Tsangpo in Tibetan, the Siang/Dihang River in Arunachali, Luit in Assamese, and Jamuna River in Bangla. It is the 9th largest river in the world by discharge, and the 15th longest. With its origin in the Manasarovar Lake region, near Mount Kailash, on the northern side of the Himalayas in Burang County of Tibet where it is known as the Yarlung Tsangpo River, It flows along southern Tibet to break through the Himalayas in great gorges (including the Yarlung Tsangpo Grand Canyon) and into Arunachal Pradesh. It flows southwest through the Assam Valley as the Brahmaputra and south through Bangladesh as the Jamuna (not to be confused with the Yamuna of India). In the vast Ganges Delta, it merges with the Ganges, popularly known as the Padma in Bangladesh, and becomes the Meghna and ultimately empties into the Bay of Bengal. About long, the Bra ...

Plate Tectonics
Plate tectonics (from the la, label=Late Latin, tectonicus, from the grc, τεκτονικός, lit=pertaining to building) is the generally accepted scientific theory that considers the Earth's lithosphere to comprise a number of large tectonic plates which have been slowly moving since about 3.4 billion years ago. The model builds on the concept of ''continental drift'', an idea developed during the first decades of the 20th century. Plate tectonics came to be generally accepted by geoscientists after seafloor spreading was validated in the mid to late 1960s. Earth's lithosphere, which is the rigid outermost shell of the planet (the crust and upper mantle), is broken into seven or eight major plates (depending on how they are defined) and many minor plates or "platelets". Where the plates meet, their relative motion determines the type of plate boundary: '' convergent'', '' divergent'', or ''transform''. Earthquakes, volcanic activity, mountain-building, and oceanic tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IPNI
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized author abbreviations. These were initially based on Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew (Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium ( APNI). The IPNI database is a collection of the names registered by the three cooperating institutions and they work towards standardizing the information. The stan ...

World Checklist Of Selected Plant Families
The World Checklist of Selected Plant Families (usually abbreviated to WCSP) is an "international collaborative programme that provides the latest peer reviewed and published opinions on the accepted scientific names and synonyms of selected plant families." Maintained by the Royal Botanic Gardens, Kew, it is available online, allowing searches for the names of families, genera and species, as well as the ability to create checklists. The project traces its history to work done in the 1990s by Kew researcher Rafaël Govaerts on a checklist of the genus ''Quercus''. Influenced by the Global Strategy for Plant Conservation, the project expanded. , 173 families of seed plants were included. Coverage of monocotyledon families is complete; other families are being added. There is a complementary project called the International Plant Names Index (IPNI), in which Kew is also involved. The IPNI aims to provide details of publication and does not aim to determine which are accepted spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
