Roscoea Scillifolia
''Roscoea scillifolia'' is a perennial herbaceous plant occurring in Yunnan in China. Most members of the ginger family (Zingiberaceae), to which it belongs, are tropical, but like other species of ''Roscoea'', ''R. scillifolia'' grows in much colder mountainous regions. , the species is only known in cultivation and may be extinct in the wild. Description ''Roscoea scillifolia'' 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. scillifolia'' varies considerably in height, extreme forms being as short at 6 cm, with some plants up to 37 cm tall; most are between 10 and 27 cm. There are up to three bladeless sheathing leaves and one to five full leaves, again varying considerably in size. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perennial
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Staminodes
In botany, a staminode is an often rudimentary, sterile or abortive stamen, which means that it does not produce pollen.Jackson, Benjamin, Daydon; ''A Glossary of Botanic Terms with their Derivation and Accent''; Published by Gerald Duckworth & Co. London, 4th ed 1928 Staminodes are frequently inconspicuous and stamen-like, usually occurring at the inner whorl of the flower, but are also sometimes long enough to protrude from the corolla. Sometimes, the staminodes are modified to produce nectar, as in the Witch Hazel ''( Hamamelis)''.jin lu mei shu. Hamamelis Linnaeus, Sp. Pl. 1: 124. 1753. Flora of China 9: 32. 2003 Staminodes can be a critical characteristic for differentiating between species, for instance in the orchid genus ''Paphiopedilum'', and among the penstemons. In the case of Cannas, the petals are inconsequential and the staminodes are refined into eye-catching petal-like replacements. A spectacular example of staminode is given by ''Couroupita guianensis'', a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |

Dali City
Dali City () is the county-level seat of the Dali Bai Autonomous Prefecture in northwestern Yunnan. Dali City is administered through 12 township-level districts, two of which are also commonly referred to as Dali. Xiaguan () formerly known as Hsia-kuan, is the modern city centre and usually conflated with Dali City by virtue of being its seat. This town is the destination of most long-distance transportation heading to Dali and is sometimes referred to as Dali New Town () to avoid confusion. Dali Town () formerly known as Tali, is another division of Dali City, located north of Xiaguan. This town, commonly referred to as Dali Old Town () to distinguish it from the city seat in Xiaguan, is usually the Dali referred to in tourist publications. The old town is one of the most popular tourist destinations in Yunnan, known for its natural scenery, historical and cultural heritage, and vibrant nightlife.

Père Jean Marie Delavay
Père Jean-Marie Delavay (28 December 1834 – 31 December 1895) was a French missionary, explorer and botanist. He was perhaps the first Western explorer of the region which is now encompassed by the ''Three Parallel Rivers of Yunnan Protected Areas''. Delavay was born in Les Gets, Haute-Savoie, in 1834. As a missionary for Missions Etrangères de Paris (Foreign Missions of Paris) he was sent to China in 1867, serving first in Guangdong, then moving to north-western Yunnan. While in France in 1881, on a break from his duties, Delavay met the natural history collector and fellow missionary Père Armand David, who had made his final collecting expedition in China in the 1870s. David encouraged Delavay to continue his collecting work and send specimens to the Paris Museum of Natural History. In 1888 he contracted bubonic plague; he survived the initial onslaught of the disease, but never fully recovered. This did not stop his explorations, however, eventually he travelled to Hon ...

Anther
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 ''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'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea''). The androecium in var ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
