Paeonia Daurica Subsp. Wittmanniana
''Paeonia daurica'' subsp. ''wittmanniana'', also known as Wittmann's peony, is a perennial peony native to the southern Transcaucasian region. It was formerly regarded as a separate species, ''Paeonia wittmanniana'', but in 2002, the Chinese botanist Hong Deyuan reduced it to a subspecies of '' Paeonia daurica''. It is closely related to another subspecies of ''P. daurica'', ''P. daurica'' subsp. ''mlokosewitschii''. ''Paeonia daurica'' subsp. ''wittmanniana'' is up to 1.5 m tall. Above the plant is glabrous and dark green; below it is lighter green, glaucescent, with white hairs especially crowded along the veins, and the lower leaves are biternate. Yellow to white flowers, 10–13 cm across, appear from April to June. The filaments are red and up to 1 cm long and the anthers are yellow to orange. The stamens are around 22 mm long. The divided leaf segments are ovate Ovate may refer to: *Ovate (egg-shaped) leaves, tepals, or other botanical parts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicolai Anders Von Hartwiss
Nicolai Anhorn von Hartwiss (Николай Андерс фон, ''де'' Гартвис, ''Николай Андреевич''; was a Livonian-born, Baltic German, Russian botanist, plant explorer and plant breeder. His education at the university in Dorpat (Livonia) was interrupted by the Napoleonic Wars 1812–1818 when he served in the Russian army. Afterwards he worked on his father's estate and by 1824 was living in Riga and had a collection of 500 varieties of fruit trees and roses. He was then appointed to the Russian Imperial Botanical Garden at Nikita where he served as a director for the rest of his career. He is remembered for his plant collection explorations of Georgia and the Crimea, and for the breeding of roses. Life Von Hartwiss was born Ritter (esquire) Nikolaus Ernst Bartholomäus Anhorn von Hartwiss, ''Hartwiß'' in 1793 at his father's estate at Kokenhof near Wolmar, Livonia (now Valmiera, Latvia). The family Anhorn von Hartwiss (double name) comes from Sw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Lindley
John Lindley FRS (5 February 1799 – 1 November 1865) was an English botanist, gardener and orchidologist. Early years Born in Catton, near Norwich, England, John Lindley was one of four children of George and Mary Lindley. George Lindley was a nurseryman and pomologist and ran a commercial nursery garden. Although he had great horticultural knowledge, the undertaking was not profitable and George lived in a state of indebtedness. As a boy he would assist in the garden and also collected wild flowers he found growing in the Norfolk countryside. Lindley was educated at Norwich School. He would have liked to go to university or to buy a commission in the army but the family could not afford either. He became Belgian agent for a London seed merchant in 1815. At this time Lindley became acquainted with the botanist William Jackson Hooker who allowed him to use his botanical library and who introduced him to Sir Joseph Banks who offered him employment as an assistant in his herba ...

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] |
Peony
The peony or paeony is a flowering plant in the genus ''Paeonia'' , the only genus in the family Paeoniaceae . Peonies are native to Asia, Europe and Western North America. Scientists differ on the number of species that can be distinguished, ranging from 25 to 40, although the current consensus is 33 known species. The relationships between the species need to be further clarified. Most are herbaceous perennial plants tall, but some are woody shrubs tall. They have compound, deeply lobed leaves and large, often fragrant flowers, in colors ranging from purple and pink to red, white or yellow, in late spring and early summer. The flowers have a short blooming season, usually only 7–10 days. Peonies are popular garden plants in temperate regions. Herbaceous peonies are also sold as cut flowers on a large scale, although generally only available in late spring and early summer.

Southern Caucasus
The South Caucasus, also known as Transcaucasia or the Transcaucasus, is a geographical region on the border of Eastern Europe and Western Asia, straddling the southern Caucasus Mountains. The South Caucasus roughly corresponds to modern Armenia, Georgia, and Azerbaijan, which are sometimes collectively known as the Caucasian States. The total area of these countries measures about . The South Caucasus and the North Caucasus together comprise the larger Caucasus geographical region that divides Eurasia. Geography The South Caucasus spans the southern portion of the Caucasus Mountains and their lowlands, straddling the border between the continents of Europe and Asia, and extending southwards from the southern part of the Main Caucasian Range of southwestern Russia to the Turkish and Armenian borders, and from the Black Sea in the west to the Caspian Sea coast of Iran in the east. The area includes the southern part of the Greater Caucasus mountain range, the entire Lesser C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of 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 produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, 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 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 specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paeonia Daurica
''Paeonia daurica'' is a perennial herbaceous plant belonging to the peony family. It has slender carrot-shaped roots, leaves mostly consisting of nine leaflets, with one flower per stem. The flower is subtended by none to two leafy bracts, and has two or three sepals, five to eight petals, and many stamens. The subspecies vary in the colour of the petals (white, light yellow, pink, red), the size and shape of the leaflets, and the hairiness of the leaflets and the carpels. ''Paeonia daurica'' can be found from the Balkans to Iran, and the Crimea to Lebanon, with the centre of its distribution in the Caucasus. It is also cultivated as an ornamental. Description ''Paeonia daurica'' is a perennial herbaceous photosynthesising plant, emerging in spring and retreating underground in the autumn. It has slender carrot-shaped roots which are directed downwards. The leaves are alternately set along the stems and have an outline of 5–11 × 8–17 cm. The lower leaves ar ...

Glabrous
Glabrousness (from the Latin ''glaber'' meaning "bald", "hairless", "shaved", "smooth") is the technical term for a lack of hair, down, setae, trichomes or other such covering. A glabrous surface may be a natural characteristic of all or part of a plant or animal, or be due to loss because of a physical condition, such as alopecia universalis in humans, which causes hair to fall out or not regrow. In botany Glabrousness or otherwise, of leaves, stems, and fruit is a feature commonly mentioned in plant keys; in botany and mycology, a ''glabrous'' morphological feature is one that is smooth and may be glossy. It has no bristles or hair-like structures such as trichomes. In anything like the zoological sense, no plants or fungi have hair or wool, although some structures may resemble such materials. The term "glabrous" strictly applies only to features that lack trichomes at all times. When an organ bears trichomes at first, but loses them with age, the term used is ''glabrescent ...

Glaucescent
''Glaucous'' (, ) is used to describe the pale grey or bluish-green appearance of the surfaces of some plants, as well as in the names of birds, such as the glaucous gull (''Larus hyperboreus''), glaucous-winged gull (''Larus glaucescens''), glaucous macaw (''Anodorhynchus glaucus''), and glaucous tanager (''Thraupis glaucocolpa''). The term ''glaucous'' is also used botanically as an adjective to mean "covered with a greyish, bluish, or whitish waxy coating or bloom that is easily rubbed off" (e.g. glaucous leaves). The first recorded use of ''glaucous'' as a color name in English was in the year 1671. Examples The epicuticular wax coating on mature plum fruit gives them a glaucous appearance. Another familiar example is found in the common grape genus (''Vitis vinifera''). Some cacti have a glaucous coating on their stem(s). Glaucous coatings are hydrophobic so as to prevent wetting by rain. Their waxy character serves to hinder climbing of leaves, stem or fruit by insect ...

Biternate
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
