Pinus Gerardiana
''Pinus gerardiana'', known as the chilgoza pine or ''neja'' is a pine native to the northwestern Himalayas in Afghanistan, northern Khyber Pakhtunkhwa, Pakistan, Waziristan and northwestern India, growing at elevations between 1800 and 3350 metres. It often occurs in association with ''Cedrus deodara'' and ''Pinus wallichiana''. Description The trees are 10-20(-25) m tall with usually deep, wide and open Crown (botany), crowns with long, erect branches. However, crowns are narrower and shallower in dense forests. The Bark (botany), bark is very flaky, peeling to reveal light greyish-green patches, similar to the closely related lacebark pine (''Pinus bungeana''). The branchlets are smooth and olive-green. The leaf, leaves are needle-like, in fascicles of 3, 6–10 cm long, spreading stiffly, glossy green on the outer surface, with blue-green stomatal lines on the inner face; the sheaths falling in the first year. The conifer cone, cones are 10–18 cm long, 9–11&nbs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nathaniel Wallich
Nathaniel Wolff Wallich FRS FRSE (28 January 1786 – 28 April 1854) was a surgeon and botanist of Danish origin who worked in India, initially in the Danish settlement near Calcutta and later for the Danish East India Company and the British East India Company. He was involved in the early development of the Calcutta Botanical Garden, describing many new plant species and developing a large herbarium collection which was distributed to collections in Europe. Several of the plants that he collected were named after him. Early life and education Nathaniel Wallich was born in Copenhagen in 1786 as Nathan Wulff Wallich. His father Wulff Lazarus Wallich (1756–1843) was a Sephardic Jewish merchant originally from the Holsatian town Altona near Hamburg, who settled in Copenhagen late in the 18th century. His mother was Hanne née Jacobson (1757–1839). Wallich attended the Royal Academy of Surgeons in Copenhagen, where his professors trained in the botanical science included ...

Himalayan Dwarf Mistletoe
''Arceuthobium minutissimum'', known as the Indian dwarf mistletoe or Himalayan dwarf mistletoe, is a leafless parasitic plant of ''Pinus wallichiana''. It is considered the smallest known dicotyledonous plant. Description Individual shoots grow to a height of 5 millimeters, and up to 1 centimeter with mature fruit. Shoots emerge from both the cortex and needles of the host plant. Flowers are monoecious, and seed dispersal occurs in September. Distribution and host species The species occurs in dry forests of the Himalayan mountains at an approximate altitude of 2500–3500 meters. It has been reported in Nepal, India, Bhutan, and Pakistan. ''A. minutissimum'' infects the crowns of trees of all ages. It severely impacts the health of host-trees, and causes the loss of needles. Although ''P. wallichiana'' is the primary host, it has been recorded to infect ''Pinus gerardiana'' in Pakistan. Unconfirmed reports show that it may also infect ''Abies pindrow'' and ''Cedrus deodara''. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trees Of Temperate Climates
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 co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edible Nuts And Seeds
An edible item is any item that is safe for humans to eat. "Edible" is differentiated from "eatable" because it does not indicate how an item tastes, only whether it is fit to be eaten. Nonpoisonous items found in nature – such as some mushrooms, insects, seaweed, and so forth – are referred to as edible. Processed items that normally are not ingested but are specially manufactured to be so, like edible underwear or edible packaging, are also labeled as edible. Edible items in nature It is estimated that approximately half of about 400,000 plant species on earth are edible, yet ''Homo sapiens'' consume only about 200 plant species, because these are the simplest to domesticate. Edible plants found in nature include certain types of mushrooms, flowers, seeds, berries, seaweed, and cacti. Being able to identify the versions of these plants that are safe to eat is an important survival skill. Many animals are also edible, including domesticated livestock as well as wild insec ...

Pinus
A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae. The World Flora Online created by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 187 species names of pines as current, together with more synonyms. The American Conifer Society (ACS) and the Royal Horticultural Society accept 121 species. Pines are commonly found in the Northern Hemisphere. ''Pine'' may also refer to the lumber derived from pine trees; it is one of the more extensively used types of lumber. The pine family is the largest conifer family and there are currently 818 named cultivars (or trinomials) recognized by the ACS. Description Pine trees are evergreen, coniferous resinous trees (or, rarely, shrubs) growing tall, with the majority of species reaching tall. The smallest are Siberian dwarf pine and Potosi pinyon, and the tallest is an tall ponderosa pine located in southern Oregon's Rogue Riv ...

Himachal Pradesh, India
Himachal Pradesh (; ; "Snow-laden Mountain Province") is a state in the northern part of India. Situated in the Western Himalayas, it is one of the thirteen mountain states and is characterized by an extreme landscape featuring several peaks and extensive river systems.

Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called peptides. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid residue ...

Carbohydrate
In organic chemistry, a carbohydrate () is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1 (as in water) and thus with the empirical formula (where ''m'' may or may not be different from ''n''), which does not mean the H has covalent bonds with O (for example with , H has a covalent bond with C but not with O). However, not all carbohydrates conform to this precise stoichiometric definition (e.g., uronic acids, deoxy-sugars such as fucose), nor are all chemicals that do conform to this definition automatically classified as carbohydrates (e.g. formaldehyde and acetic acid). The term is most common in biochemistry, where it is a synonym of saccharide (), a group that includes sugars, starch, and cellulose. The saccharides are divided into four chemical groups: monosaccharides, disaccharides, oligosaccharides, and polysaccharides. Monosaccharides and disaccharides, the smallest (lower molecular wei ...
