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 Wat ...

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, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide 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 trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported cle ...

Rosa Roxburghii
''Rosa roxburghii'' (burr rose, chestnut rose, chinquapin rose, or cili), is a species of flowering plant in the family Rosaceae, native to the eastern Himalayas, Tibet, and central and southern China. In the wild, it is found in thickets, mountain forests, on slopes, and alongside streams, typically above sea level. A diffuse shrub capable of reaching but usually shorter, it is available from commercial suppliers. In China, it is cultivated for its vitamin C-rich hips on , mostly in Guizhou. It was dedicated to William Roxburgh, a Scottish physician and botanist who was director of the Calcutta Botanical Garden. Three forms have been recognized: ''Rosa roxburghii'' f. ''roxburghii'', which has double or semi-double, reddish or pink flowers in diametre'', Rosa roxburghii'' f. ''normalis'' Rehder & E. H. Wilson (in Sargent, Pl. Wilson. 2: 318. 1915), which has simple, pink flowers in diametre and also, ''Rosa roxburghii'' f. ''hirtula'' (Regel) (Rehder and Wilson), flowers si ...

Whole Genome Sequencing
Whole genome sequencing (WGS), also known as full genome sequencing or just genome sequencing, is the process of determining 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. Whole genome sequencing should not be confused with DNA ...

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, Marischal College, Aberdeen, and later attended both the University of Aberdeen and the University of Glasgow. He received the degrees of Bachelor of Medicine, Bachelor of Surgery, M.B. and Doctor of Medicine, C.M. in 1873. He enjoyed teaching and joined the University of Glasgow as a prodissector to the Profe ...

Manipur
Manipur () is a state in northeastern India with Imphal as its capital. It borders the Indian states of Assam to the west, Mizoram to the south, and Nagaland to the north and shares the international border with Myanmar, specifically the Sagaing Region to the east and Chin State to the southeast. Covering an area of 22,330 square kilometers (8,621 mi²), the state consists mostly of hilly terrain with the 1813-square-kilometre (700 mi²) Imphal Valley inhabited by the Meitei (Manipuri) community, historically a kingdom. Surrounding hills are home to Naga and Kuki-Zo communities, who speak Tibeto-Burman languages. The official language and lingua franca, Meitei (Manipuri), also belongs to the Tibeto-Burman family. During the days of the British Raj, Manipur was one of the princely states. Prior to the British departure in 1947, Manipur acceded to the Dominion of India, along with roughly 550 other princely states. In September 1949, the ruler of Manipur signed ...

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 (botany), stratification), with some such as ''Rosa canina'' only germinating after two winter chill periods. Uses Rose hips are used in bread and pies, Hagebuttenmark, jam, Fruit preserves#Jelly, jelly, marmalade, syrup, rose hip soup, soup, herbal tea, tea, Fruit wine#Rose hip wine, wine, and other beverages. Rose hips can be eaten raw, like berries, if care is taken to avoid the h ...

Flower
Flowers, also known as blooms and blossoms, are the reproductive structures of flowering plants ( angiosperms). Typically, they are structured in four circular levels, called whorls, around the end of a stalk. These whorls include: calyx, modified leaves; corolla, the petals; androecium, the male reproductive unit consisting of stamens and pollen; and gynoecium, the female part, containing style and stigma, which receives the pollen at the tip of the style, and ovary, which contains the ovules. When flowers are arranged in groups, they are known collectively as inflorescences. Floral growth originates at stem tips and is controlled by MADS-box genes. In most plant species flowers are heterosporous, and so can produce sex cells of both sexes. Pollination mediates the transport of pollen to the ovules in the ovaries, to facilitate sexual reproduction. It can occur between different plants, as in cross-pollination, or between flowers on the same plant or even the same f ...

Leaf
A leaf (: leaves) is a principal appendage of the plant stem, stem of a vascular plant, usually borne laterally above ground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the Shoot (botany), shoot system. In most leaves, the primary Photosynthesis, photosynthetic Tissue (biology), 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. The leaf is an integral part of the stem system, and most leaves are flattened and have distinct upper (Glossary of botanical terms#adaxial, adaxial) and lower (Glossary of botanical terms#abaxial, abaxial) surfaces that differ in color, Trichome, hairiness, the number of stomata (pores that intake and output gases), the amount and ...

Variety (botany)
In botanical nomenclature, variety (abbreviated var.; in ) 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'', 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. Definitions The term is defined in different ways by different authors. However, the International Code of Nomenclature for Cultivated Plants, while recognizing ...
