Rosa Gigantea
''Rosa gigantea'' is a species of rose native to northeast India, northern Myanmar and southwest China (Yunnan) in the foothills of the Himalaya at 1000–1500 m altitude. It is sometimes considered to be a variety of ''Rosa odorata'', as ''R. odorata'' var. ''gigantea''. As its name suggests, it is the largest species of rose, climbing 20 m or more into the crowns of other trees by means of its stout, hooked thorns, and with a trunk up to 50 cm diameter. The leaves are semi-evergreen, 15–25 cm long, pinnate, with usually 7 leaflets, each leaflet 4–8 cm long. The flowers are white, creamy or yellow, the largest of any wild rose, 10–14 cm diameter. The hips are yellow or orange, 2.5–3.5 cm diameter, hard, and often lasting through the winter into the following spring, often still present at the same time as the next years' flowers. Another rose, described from Manipur in 1888 as ''R. macrocarpa'' and ''R. xanthocarpa'' by Sir George Watt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Collett
Sir Henry Collett (6 March 1836 – 21 December 1901) was an English soldier and botanist. He served as an army officer in the East India Company. Life Collett was born in Thetford, Norfolk, the fourth son of Rev. W. Collett and his second wife Ellen Clarke née Bidwell, He studied at Tonbridge School and at Addiscombe Military Seminary. He joined the Bengal Army on 8 June 1855, rising through the ranks to become a lieutenant colonel in 1879. In the Second Anglo-Afghan War (1878–80) he acted as quartermaster general on the staff of Frederick Roberts, 1st Earl Roberts.

Tree
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Whole Genome Sequencing
Whole genome sequencing (WGS), also known as full genome sequencing, complete genome sequencing, or entire genome sequencing, is the process of determining the entirety, or nearly the entirety, of the DNA sequence of an organism's genome at a single time. This entails sequencing all of an organism's chromosomal DNA as well as DNA contained in the mitochondrial DNA, mitochondria and, for plants, in the chloroplast. Whole genome sequencing has largely been used as a research tool, but was being introduced to clinics in 2014. In the future of personalized medicine, whole genome sequence data may be an important tool to guide therapeutic intervention. The tool of DNA sequencing, gene sequencing at Single-nucleotide polymorphism, SNP level is also used to pinpoint functional variants from association studies and improve the knowledge available to researchers interested in evolutionary biology, and hence may lay the foundation for predicting disease susceptibility and drug response. ...

George Watt (botanist)
Sir George Watt (24 April 1851 – 2 April 1930) was a Scottish physician and botanist who worked in India as "Reporter" on economic botany and during the course of his career in India he compiled a major multivolume work, ''The'' ''Dictionary of Economic Products of India'', the last volume of which was published in 1893. An abridged edition of his work was also published as the single volume ''Commercial Products of India'' in 1908. He is honoured in the binomials of several plants named after him. Life and career Watt was born in Old Meldrum, Aberdeenshire, Scotland, the third son of John Watt. He was educated at Grammar School, King's College and Marischal College, Aberdeen, and later attended both the University of Aberdeen and the University of Glasgow. He received the degrees of M.B. and C.M. in 1873. He enjoyed teaching and joined the University of Glasgow as a prodissector to the Professor of Anatomy. Around 1864, there was a famine in Orissa and the then Lieutenan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manipur
Manipur () ( mni, Kangleipak) is a state in Northeast India, with the city of Imphal as its capital. It is bounded by the Indian states of Nagaland to the north, Mizoram to the south and Assam to the west. It also borders two regions of Myanmar, Sagaing Region to the east and Chin State to the south. The state covers an area of . Manipur has been at the crossroads of Asian economic and cultural exchange for more than 2,500 years. It connects the Indian subcontinent and Central Asia to Southeast Asia, East Asia, Siberia, regions in the Arctic, Micronesia and Polynesia enabling migration of people, cultures and religions. During the days of the British Indian Empire, the Kingdom of Manipur was one of the princely states. Between 1917 and 1939, some people of Manipur pressed the princely rulers for democracy. By the late 1930s, the princely state of Manipur negotiated with the British administration its preference to continue to be part of the Indian Empire, rather than part of B ...

Rose Hip
The rose hip or rosehip, also called rose haw and rose hep, is the accessory fruit of the various species of rose plant. It is typically red to orange, but ranges from dark purple to black in some species. Rose hips begin to form after pollination of flowers in spring or early summer, and ripen in late summer through autumn. Propagation Roses are propagated from rose hips by removing the achenes that contain the seeds from the hypanthium (the outer coating) and sowing just beneath the surface of the soil. The seeds can take many months to germinate. Most species require chilling (stratification), with some such as ''Rosa canina'' only germinating after two winter chill periods. Use Rose hips are used in bread and pies, jam, jelly, marmalade, syrup, soup, tea, wine, and other beverages. Rose hips can be eaten raw, like berries, if care is taken to avoid the hairs inside the fruit. The hairs are used as itching powder. A few rose species are sometimes grown for the ornament ...

Flower
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light ...

Variety (botany)
In botanical nomenclature, variety (abbreviated var.; in la, varietas) is a taxonomic rank below that of species and subspecies, but above that of form. As such, it gets a three-part infraspecific name. It is sometimes recommended that the subspecies rank should be used to recognize geographic distinctiveness, whereas the variety rank is appropriate if the taxon is seen throughout the geographic range of the species. Example The pincushion cactus, ''Escobaria vivipara'' (Nutt.) Buxb., is a wide-ranging variable species occurring from Canada to Mexico, and found throughout New Mexico below about . Nine varieties have been described. Where the varieties of the pincushion cactus meet, they intergrade. The variety ''Escobaria vivipara'' var. ''arizonica'' is from Arizona, while ''Escobaria vivipara'' var. ''neo-mexicana'' is from New Mexico. See also '' Capsicum annuum var. glabriusculum'' Definitions The term is defined in different ways by different authors. However, the I ...
