Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Circaea Alpina
''Circaea alpina'', commonly called alpine enchanter's nightshade or small enchanter's nightshade, is a 10–30 cm tall perennial herb found in cool forests of the Northern Hemisphere. Description The leaves are opposite, ovate, 2–6 cm and coarsely dentate. The petioles have a wing beneath. The flowers and fruits are clustered near the top of the fruiting raceme; each raceme bears 15 or less white or pink flowers in mid-May through early September. Each flower has two white to light pink petals long with two lobes. The two white sepals are long. The fruit is a small bur with one seed. ''C. alpina'' can reproduce vegetatively and via stolons. Distribution In North America, ''Circaea alpina'' is distributed throughout all of Canada and North Carolina through Maine and New Mexico through Washington. In Eurasia, the range of ''C. alpina'' includes Northern Europe south to Albania and Bulgaria and east to Korea and Japan. ''C. alpina'' prefers a moist, upland habitat ...

Plants Of The World Online
Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew. It was launched in March 2017 with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". The initial focus was on tropical African Floras, particularly Flora Zambesiaca, Flora of West Tropical Africa and Flora of Tropical East Africa. The database uses the same taxonomical source as Kew's World Checklist of Selected Plant Families, which is the International Plant Names Index, and the World Checklist of Vascular Plants (WCVP). POWO contains 1,234,000 global plant names and 367,600 images. See also *Australian Plant Name Index *Convention on Biological Diversity *World Flora Online *Tropicos Tropicos is an online botanical database containing taxonomic information on plants, mainly from the Neotropical realm (Central, and South America). It is maintained by the Missouri Botanical Garden and was established over 25 y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Botanic Gardens, Kew
Royal Botanic Gardens, Kew is a non-departmental public body in the United Kingdom sponsored by the Department for Environment, Food and Rural Affairs. An internationally important botanical research and education institution, it employs 1,100 staff. Its board of trustees is chaired by Dame Amelia Fawcett. The organisation manages botanic gardens at Kew in Richmond upon Thames in south-west London, and at Wakehurst, a National Trust property in Sussex which is home to the internationally important Millennium Seed Bank, whose scientists work with partner organisations in more than 95 countries. Kew, jointly with the Forestry Commission, founded Bedgebury National Pinetum in Kent in 1923, specialising in growing conifers. In 1994, the Castle Howard Arboretum Trust, which runs the Yorkshire Arboretum, was formed as a partnership between Kew and the Castle Howard Estate. In 2019, the organisation had 2,316,699 public visitors at Kew, and 312,813 at Wakehurst. Its site at Kew ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circaea
The ''Circaea'', or enchanter's nightshades, are a genus of flowering plants in the evening primrose family Onagraceae. About two dozen taxa have been described, including eight species. Plants of the genus occur throughout the temperate and boreal forests of the Northern Hemisphere. Three taxa occur in North America: '' Circaea alpina'', '' Circaea canadensis'', and the hybrid ''Circaea'' × ''sterilis''. The generic name ''Circaea'' refers to the enchantress Circe from Greek mythology who is said to have used the herb as a charm. Description Members of genus ''Circaea'' are perennial, herbaceous plants with erect stems, which may or may not be branched. The stem leaves are opposite and petiolate, with toothed edges (i.e., with dentate leaf margins). The inflorescence is a terminal, erect raceme, with additional racemes at the apices of stem branches (if any). Flowers are dimerous with 2 sepals, 2 petals, and 2 stamens. The sepals, petals, and stamens alt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
