Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (/ ˌ æ n dʒ i ə ˈ s p ər m iː /). [5] [6] The term 'angiosperm' is derived from the Greek words ἀγγεῖον / angeion ('container, vessel') and σπέρμα / sperma ('seed'), meaning that the seeds are enclosed within a fruit. The group was ...
The species is widely cultivated as an ornamental plant for its flowers. In areas too cold for winter survival, it can be grown as an annual plant. Since it is of tropical origin, it flowers best under a summer short-day photoperiod. Though it can be successfully flowered in the north, its flowering is impaired by excessively long summer days.
The fossil history of flowering plants records the development of flowers and other distinctive structures of the angiosperms, now the dominant group of plants on land.The history is controversial as flowering plants appear in great diversity in the Cretaceous, with scanty and debatable records before that, creating a puzzle for evolutionary biologists that Charles Darwin named an "abominable ...
Ipomoea sepiaria, is part of the Dashapushpam (Ten sacred flowers) in Kerala and is known as "Thiruthali" in Malayalam. [ 8 ] [ 9 ] Moon vine ( I. alba ) sap was used for vulcanization of the latex of Castilla elastica (Panama rubber tree, Nahuatl : olicuáhuitl ) to rubber ; as it happens, the rubber tree seems well-suited for the vine to ...
Some moonflowers, which flower at night, are also in the morning glory family. Because of their fast growth, twining habit, attractive flowers, and tolerance for poor, dry soils, some morning glories are excellent vines for creating summer shade on building walls when trellised, thus keeping the building cooler and reducing heating and cooling ...
Flowering plants, also known as angiosperms, spread during this period, although they did not become predominant until near the end of the period (Campanian age). [18] Their evolution was aided by the appearance of bees; in fact angiosperms and insects are a good example of coevolution.
Flower of Liriodendron tulipifera, a Mesangiosperm. Mesangiospermae is a clade that contains the majority of flowering plants (angiosperms). Mesangiosperms are therefore known as the core angiosperms, in contrast to the three orders of earlier-diverging species known as the basal angiosperms: Nymphaeales (including water lilies), Austrobaileyales (including star anise), and Amborellales.
Although at one time considered angiosperms because of their berry-like cupules, [5] that hypothesis was later disproven. [6] Nevertheless, some authorities consider them likely ancestors or close relatives of angiosperms. [7] The origin of angiosperms remains unclear, and they cannot be linked with any known seed plants groups with certainty.
