Sarcococca Hookeriana
''Sarcococca hookeriana'', the Himalayan sweet box, is a species of flowering plant in the box family Buxaceae, native to China, Afghanistan, North East India, Bhutan and Nepal. It is a low-growing evergreen shrub, usually growing to high. It produces aromatic white flowers throughout winter, followed by black berries. ''Sarcococca hookeriana'' has several varieties of very different appearance to which different nomenclature has been applied in the references. Recent convention for example is to use ''Sarcococca hookeriana'' var. ''humilis'' for the previous ''Sarcococca humilis'', although it has broader, shiny leaves and a different habit than other forms. This small plant is often used as groundcover in gardens. The variety ''Sarcococca hookeriana'' var. ''digyna'' is more slender with narrower leaves. The cultivar ‘Purple Stem’ has gained the Royal Horticultural Society's Award of Garden Merit. It is fully hardy Hardy may refer to: People * Hardy (surname) * Hard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hardiness (plants)
Hardiness of plants describes their ability to survive adverse growing conditions. It is usually limited to discussions of climatic adversity. Thus a plant's ability to tolerate cold, heat, drought, flooding, or wind are typically considered measurements of hardiness. Hardiness of plants is defined by their native extent's geographic location: longitude, latitude and elevation. These attributes are often simplified to a hardiness zone. In temperate latitudes, the term most often describes resistance to cold, or "cold-hardiness", and is generally measured by the lowest temperature a plant can withstand. Hardiness of a plant is usually divided into two categories: tender, and hardy. (Some sources also use the erroneous terms "Half-hardy" or "Fully hardy".) Tender plants are those killed by freezing temperatures, while hardy plants survive freezing—at least down to certain temperatures, depending on the plant. "Half-hardy" is a term used sometimes in horticulture to describe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Nepal
The Flora of Nepal is one of the richest in the world due to the diverse climate, topology and geography of the country. Research undertaken in the late 1970s and early 1980s documented 5067 species of which 5041 were angiosperms and the remaining 26 species were gymnosperms. The Terai area has hardwood, bamboo, palm, and sal trees. Notable plants include the garden angelica, '' Luculia gratissima'', '' Meconopsis villosa'', and '' Persicaria affinis''. However, according to ICOMOS checklist (as of 2006), in the protected sites, there are 2,532 species of vascular plants under 1,034 genera and 199 families. The variation in figures is attributed to inadequate floral coverage filed studies. There are 400 species of vascular plants which are endemic to Nepal. Of these, two in particular are orchids '' Pleione coronaria'' and '' Oreorchis porphyranthes.'' The most popular endemic plant of Nepal is rhododendron (arboreum) which in Nepali language is called ''lali guras''. See als ...

Flora Of Bhutan
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurman ...

Flora Of China
The flora of China consists of a diverse range of plant species including over 39,000 vascular plants, 27,000 species of fungi and 3000 species of bryophytes.Wu, Z. Y., P. H. Raven & D. Y. Hong, eds. 2006. Flora of China. Vol. 22 (Poaceae). Science Press, Beijing, and Missouri Botanical Garden Press, St. Louis More than 30,000 plant species are native to China, representing nearly one-eighth of the world's total plant species, including thousands found nowhere else on Earth. China's land, extending over 9.6 million km, contains a variety of ecosystems and climates for plants to grow in. Some of the main climates include shores, tropical and subtropical forests, deserts, elevated plateaus and mountains. The events of the continental drift and early Paleozoic Caledonian movement also play a part in creating climatic and geographical diversity resulting in high levels of endemic vascular flora. These landscapes provide different ecosystems and climates for plants to grow in, cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarcococca
''Sarcococca'' (sweet box or Christmas box) is a genus of 11 species of flowering plants in the box family Buxaceae, native to eastern and southeastern Asia and the Himalayas. They are slow-growing, monoecious, evergreen shrubs tall. The leaves are borne alternately, 3–12 cm long and 1–4 cm broad. The plants bear fragrant white flowers, often in winter. The fruit is a red or black drupe containing 1–3 seeds. Some species are cultivated as groundcover or low hedging in moist, shady areas. The basic chromosome number for genus is 14 (2n = 28). The genus name ''Sarcococca'' comes from the Greek σάρξ (''sárx'') and κόκκος (''kókkos'') for "fleshy berry", referring to the black fruit.

Carpel
Gynoecium (; ) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of (one or more) '' pistils'' and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the " female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridia within the androecium. Flowers that bear a gynoecium but no stamens are call ...

Joseph Dalton Hooker
Sir Joseph Dalton Hooker (30 June 1817 – 10 December 1911) was a British botanist and explorer in the 19th century. He was a founder of geographical botany and Charles Darwin's closest friend. For twenty years he served as director of the Royal Botanical Gardens, Kew, succeeding his father, William Jackson Hooker, and was awarded the highest honours of British science. Biography Early years Hooker was born in Halesworth, Suffolk, England. He was the second son of the famous botanist Sir William Jackson Hooker, Regius Professor of Botany, and Maria Sarah Turner, eldest daughter of the banker Dawson Turner and sister-in-law of Francis Palgrave. From age seven, Hooker attended his father's lectures at Glasgow University, taking an early interest in plant distribution and the voyages of explorers like Captain James Cook. He was educated at the Glasgow High School and went on to study medicine at Glasgow University, graduating M.D. in 1839. This degree qualified ...

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus '' Homo'' and within this genus to the species '' Homo sapiens''. '' Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Award Of Garden Merit
The Award of Garden Merit (AGM) is a long-established annual award for plants by the British Royal Horticultural Society (RHS). It is based on assessment of the plants' performance under UK growing conditions. History The Award of Garden Merit is a mark of quality awarded, since 1922, to garden plants (including trees, vegetables and decorative plants) by the United Kingdom, Royal Horticultural Society (RHS). Awards are made annually after plant trials intended to judge the plants' performance under UK growing conditions. Trials may last for one or more years, depending on the type of plant being analyzed, and may be performed at Royal Horticulture Society Garden in Wisley and other gardens or after observation of plants in specialist collections. Trial reports are made available as booklets and on the website. Awards are reviewed annually in case plants have become unavailable horticulturally, or have been superseded by better cultivars. Similar awards The award should not b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
