''Sorbus oligodonta'', the kite-leaf rowan, is a species of rowan native to northern Yunnan, southeastern Tibet Tibet (; ''Böd''; ) is a region in East Asia, covering much of the Tibetan Plateau and spanning about . It is the traditional homeland of the Tibetan people. Also resident on the plateau are some other ethnic groups such as Monpa, Taman ..., and western Sichuan in China as well as to Myanmar.Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins . It is a small to medium-sized deciduous tree growing to 5–15 m tall, with a rounded crown and dark grey Bark (botany), bark, and slender shoots. The leaf, leaves are green to slightly glaucous-green above, paler beneath, 10–18 cm long, leaf shape, pinnate with 9-17 oval leaflets 3–4.5 cm long and 1–2 cm broad, broadest near the apex (hence the English name 'kite-leaf'), rounded at the end with a short acuminate apex, and very finely serrated margins; the basal leaflets are smaller th ...

Jules Cardot
Jules Cardot (18 August 1860 – 22 November 1934) was a French people, French botany, botanist and bryology, bryologist considered in his time one of the world's leading experts on the mosses of Antarctica. He was the son-in-law of botanist Louis Alexandre Henri Joseph Piré, Louis Piré. His collection of herbarium specimens at his laboratories in Charleville, Marne, Charleville was heavily looted and damaged during World War I. The French Academy of Sciences awarded the 1893 "Prix Montague" to Cardot for his work on mosses. Cardot named 40 genera and 1200 species. Works *Cardot, J.

Fruit
In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; in fact, humans and many animals have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language usage, "fruit" normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet or sour and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term "fruit" also i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sorbus
''Sorbus'' is a genus of over 100 species of trees and shrubs in the rose family, Rosaceae. Species of ''Sorbus'' (''s.l.'') are commonly known as whitebeam, rowan ( mountain-ash) and service tree. The exact number of species is disputed depending on the circumscription of the genus, and also due to the number of apomictic microspecies, which some treat as distinct species, but others group in a smaller number of variable species.

Hubei
Hubei (; ; alternately Hupeh) is a landlocked province of the People's Republic of China, and is part of the Central China region. The name of the province means "north of the lake", referring to its position north of Dongting Lake. The provincial capital, Wuhan, serves as a major transportation hub and the political, cultural, and economic hub of central China. Hubei's name is officially abbreviated to "" (), an ancient name associated with the eastern part of the province since the State of E of the Western Zhou dynasty of –771 BCE; a popular name for Hubei is "" () (suggested by that of the powerful State of Chu, which existed in the area during the Eastern Zhou dynasty of 770 – 256 BCE). Hubei borders the provinces of Henan to the north, Anhui to the east, Jiangxi to the southeast, Hunan to the south, Chongqing to the west, and Shaanxi to the northwest. The high-profile Three Gorges Dam is located at Yichang, in the west of the province. Hubei is the 7th-largest p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sorbus Hupehensis
''Sorbus hupehensis'' (Hupeh rowan or Hubei rowan; ) is a species of rowan native to central and western China (between Qinghai and Gansu in the west, Yunnan in the south, Jiangxi in the southeast, and Shandong in the east). It is a small deciduous tree growing to 5–10 m tall, with grey-brown to purplish-brown bark. The branches and shoots are slender. The leaves are green above, paler beneath, 10–15 cm long, pinnate with 7-17 narrow oval leaflets 3–5 cm long and 1–1.8 cm broad, with an acute apex, and serrated margins. They change to orange or red in autumn. The flowers are 5–7 mm diameter, with five white petals and 20 yellowish-white stamens; they are produced in corymbs 6–10 cm diameter in late spring to early summer. The fruit is a pome 5–8 mm diameter, bright pink with persistent sepals, maturing in late autumn. There are two varieties: *''Sorbus hupehensis'' var. ''hupehensis''. Leaves with 9-17 narrow leaflets. Most of the spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cultivar
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated variety ...

Ornamental Tree
Ornamental plants or garden plants are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost any types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents. aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and foliage plants. The cultivation of ornamental plants comes under floriculture and tree nurseries, which is a ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apomixis
In botany, apomixis is asexual reproduction without fertilization. Its etymology is Greek for "away from" + "mixing". This definition notably does not mention meiosis. Thus "normal asexual reproduction" of plants, such as propagation from cuttings or leaves, has never been considered to be apomixis, but replacement of the seed by a plantlet or replacement of the flower by bulbils were categorized as types of apomixis. Apomictically produced offspring are genetically identical to the parent plant. Some authors included all forms of asexual reproduction within apomixis, but that generalization of the term has since died out. In flowering plants, the term "apomixis" is commonly used in a restricted sense to mean agamospermy, i.e., clonal reproduction through seeds. Although agamospermy could theoretically occur in gymnosperms, it appears to be absent in that group. Apogamy is a related term that has had various meanings over time. In plants with independent gametophytes (notably ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tetraploid
Polyploidy is a condition in which the cells of an organism have more than one pair of ( homologous) chromosomes. Most species whose cells have nuclei (eukaryotes) are diploid, meaning they have two sets of chromosomes, where each set contains one or more chromosomes and comes from each of two parents, resulting in pairs of homologous chromosomes between sets. However, some organisms are polyploid. Polyploidy is especially common in plants. Most eukaryotes have diploid somatic cells, but produce haploid gametes (eggs and sperm) by meiosis. A monoploid has only one set of chromosomes, and the term is usually only applied to cells or organisms that are normally diploid. Males of bees and other Hymenoptera, for example, are monoploid. Unlike animals, plants and multicellular algae have life cycles with two alternating multicellular generations. The gametophyte generation is haploid, and produces gametes by mitosis, the sporophyte generation is diploid and produces spores by meio ...

Sorbus Glabrescens
''Sorbus glabrescens'' (white-fruited rowan) is a species of rowan native to Yunnan in China.Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins . It is a small to medium-sized deciduous tree growing to 8–15 m tall with a rounded crown and dark grey bark and stout shoots. The leaves are glaucous blue-green above, paler beneath, 10–26 cm long, pinnate with 11-17 oval leaflets 3–5.5 cm long and 1–2 cm broad, broadest near the middle, rounded at the end with a short acuminate apex, and very finely serrated margins. They change to an orange or red in late autumn, much later than most other rowan species. The flowers are 8 mm diameter, with five white petals and 20 yellowish-white stamens; they are produced in corymbs 9–15 cm diameter in late spring to early summer. The fruit is a pome 7–8 mm diameter, white with a small persistent pinkish carpel, maturing in late autumn; the fruit stalks are distinctively red. The fruit commonly p ...

Seed
A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote, and grows within the mother plant to a certain size before growth is halted. The seed coat arises from the integuments of the ovule. Seeds have been an important development in the reproduction and success of vegetable gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses and liverworts, which do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates. The term "seed" also has a general me ...

Bohemian Waxwing
The Bohemian waxwing (''Bombycilla garrulus'') is a starling-sized passerine bird that breeds in the northern forests of the Palearctic and North America. It has mainly buff-grey plumage, black face markings and a pointed crest. Its wings are patterned with white and bright yellow, and some feather tips have the red waxy appearance that give this species its English name. The three subspecies show only minor differences in appearance. Females are similar to males, although young birds are less well-marked and have few or no waxy wingtips. Although the Bohemian waxwing's range overlaps those of the cedar and Japanese waxwings, it is easily distinguished from them by size and plumage differences. The breeding habitat is coniferous forests, usually near water. The pair build a lined cup-shaped nest in a tree or bush, often close to the trunk. The clutch of 3–7 eggs is incubated by the female alone for 13–14 days to hatching. The chicks are altricial and naked, and are ...
