Style (botany)
In botany, the style of an angiosperm flower is an organ of variable length that connects the ovary to the stigma. The style does not contain ovules; these are limited to the region of the gynoecium (female organs of the flower) called the "ovary". Structure The style is a narrow extension of the ovary, usually pointing upwards, connecting the ovary to the stigmatic papillae. It may be absent in some plants; in this case, it is referred to as a sessile stigma. Styles generally resemble more or less long tubes. The style can be open (with few cells occupying the central part, or even none), featuring a central canal that may be filled with mucilage. Alternatively, the style can be closed (completely filled with cells). Most plants with syncarpous pistils ( monocotyledons and some eudicotys) have open styles, whereas many eudicots and grasses have closed (solid) styles containing specialized secretory tissues, which connect the stigma to the center of the ovary. These tissu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crocus
''Crocus'' (; plural: crocuses or croci) is a genus of seasonal flowering plants in the family Iridaceae (iris family) comprising about 100 species of perennial plant, perennials growing from corms. They are low growing plants, whose flower stems remain underground, that bear relatively large white, yellow, orange or purple flowers and then become dormant after flowering. Many are cultivated for their flowers, appearing in autumn, winter, or spring. The flowers close at night and in overcast weather conditions. The crocus has been known throughout recorded history, mainly as the source of saffron. Saffron is obtained from the dried Stigma (botany), stigma of ''Crocus sativus'', an autumn-blooming species. It is valued as a spice and dyestuff, and is one of the most expensive spices in the world. Iran is the center of saffron production. Crocuses are native plant, native to woodland, scrub, and meadows from sea level to alpine tundra from the Mediterranean Sea, Mediterranean, throu ...

Allium
''Allium'' is a large genus of monocotyledonous flowering plants with around 1000 accepted species, making ''Allium'' the largest genus in the family Amaryllidaceae and among the largest plant genera in the world. Many of the species are edible, and some have a long history of cultivation and human consumption as a vegetable including the onion, garlic, scallion, scallions, shallot, shallots, leek, leeks, and chives, with onions being the second most grown vegetable globally after tomatoes as of 2023. ''Allium'' species occur in temperate climates of the Northern Hemisphere, except for a few species occurring in Chile (such as ''A. juncifolium''), Brazil (''A. sellovianum''), and tropical Africa (Allium spathaceum, ''A. spathaceum''). They vary in height between . The flowers form an umbel at the top of a leafless stalk. The bulbs vary in size between species, from small (around 2–3 mm in diameter) to rather large (8–10 cm).

Boraginaceae
Boraginaceae, the Borago, borage or forget-me-not family, includes about 2,000 species of shrubs, trees, and herbs in 146 to 154 genus, genera with a worldwide distribution. The APG IV system from 2016 classifies the Boraginaceae as single family of the order Boraginales within the asterids. Under the older Cronquist system, it was included in the Lamiales, but clearly is no more similar to the other families in this order than it is to families in several other asterid orders. A revision of the Boraginales, also from 2016, split the Boraginaceae into 11 distinct families: Boraginaceae ''sensu stricto'', Codonaceae, Coldeniaceae, Cordiaceae, Ehretiaceae, Heliotropiaceae, Hoplestigmataceae, Hydrophyllaceae, Lennoaceae, Namaceae, and Wellstediaceae. These plants have alternately arranged leaves, or a combination of alternate and opposite leaves. The leaf blades usually have a narrow shape; many are linear or lance-shaped. They are smooth-edged or toothed, and some have petiole (bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rosaceae
Rosaceae (), the rose family, is a family of flowering plants that includes 4,828 known species in 91 genera. The name is derived from the type genus '' Rosa''. The family includes herbs, shrubs, and trees. Most species are deciduous, but some are evergreen. They have a worldwide range but are most diverse in the Northern Hemisphere. Many economically important products come from the Rosaceae, including various edible fruits, such as apples, pears, quinces, apricots, plums, cherries, peaches, raspberries, blackberries, loquats, strawberries, rose hips, hawthorns, and almonds. The family also includes popular ornamental trees and shrubs, such as roses, meadowsweets, rowans, firethorns, and photinias. Among the most species-rich genera in the family are '' Alchemilla'' (270), '' Sorbus'' (260), ''Crataegus'' (260), '' Cotoneaster'' (260), '' Rubus'' (250), and ''Prunus'' (200), which contains the plums, cherries, peaches, apricots, and almonds.

Iris Versicolor
''Iris versicolor'' or ''Iris versicolour'' is also commonly known as the blue flag, harlequin blueflag, larger blue flag, northern blue flag, and poison flag, plus other variations of these names, and in Great Britain and Ireland as purple iris. It is a species of '' Iris'' native to North America, in Eastern Canada and the Eastern United States. It is common in sedge meadows, marshes, and along streambanks and shores.

Lapeirousia
''Lapeirousia'' is a genus in the plant family Iridaceae. It is endemic to sub-Saharan Africa, about a third of the species occurring in fynbos. Origin of genus name The genus ''Lapeirousia'' was described by Pierre André Pourret in Mém. Acad. Sci. Toulouse 3 : 79 (1788); Bak. In FC. 6 : 88 (1896) in part; Goldblatt in Contrib. Bol. Herb. 4 : 1 (1972); Sölch & Roessl. in FSWA. 155 : 6 (1969). Chasmatocallis Foster in Contrib. Gray Herb. 127 : 40 (1939).Dyer, R. Allen, “The Genera of Southern African Flowering Plants”. , 1975 He named the genus in honour of his friend, the botanist Philippe-Isidore Picot de Lapeyrouse. The inconsistent spellings of that name no doubt led to the original genus name being spelt "Lapeirousia" and contributed to various subsequent misspellings of the genus in various reference sources, notably "Lapeyrousia".Chittenden, Fred J.

''Freesia'' is a genus of herbaceous perennial flowering plants in the family Iridaceae, first described as a genus in 1866 by Christian Friedrich Ecklon (1886) and named after the German botanist and medical practitioner, Friedrich Freese (1795–1876). It is native to the eastern side of southern Africa, from Kenya south to South Africa, most species being found in Cape Provinces. Species of the former genus ''Anomatheca'' are now included in ''Freesia''. The plants commonly known as "freesias", with fragrant funnel-shaped flowers, are cultivated hybrids of a number of ''Freesia'' species. Some other species are also grown as ornamental plants. Description They are herbaceous plants which grow from a conical corm diameter, which sends up a tuft of narrow leaves long, and a sparsely branched stem tall bearing a few leaves and a loose one-sided spike of flowers with six petals.
