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] commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees , shrubs and vines , and most aquatic plants .
Land plants evolved from a group of freshwater green algae, perhaps as early as 850 mya, [3] but algae-like plants might have evolved as early as 1 billion years ago. [2] The closest living relatives of land plants are the charophytes, specifically Charales; if modern Charales are similar to the distant ancestors they share with land plants, this means that the land plants evolved from a ...
Sexual selection in flowering plants. Sexual selection is described as natural selection arising through preference by one sex for certain characteristics in individuals of the other sex. Sexual selection is a common concept in animal evolution but, with plants, it is often overlooked because many plants are hermaphrodites.
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 ...
The timeline displays a graphical representation of the adaptations; the text attempts to explain the nature and robustness of the evidence. Plant evolution is an aspect of the study of biological evolution, predominantly involving evolution of plants suited to live on land, greening of various land masses by the filling of their niches with ...
Lycoris squamigera is an herbaceous plant with basal, simple leaves, which are not present when the flowers emerge from the crown. The leaves sprout and grow in the spring, then die back during June; flowers appear in late July or early August. The flowers are white or pink and fragrant. The flowers spring dramatically from the ground in mid to ...
Euphorbia is a very large and diverse genus of flowering plants, commonly called spurge, in the family Euphorbiaceae . Euphorbias range from tiny annual plants to large and long-lived trees. [ 2] with perhaps the tallest being Euphorbia ampliphylla at 30 m (98 ft) or more. [ 3][ 4] The genus has roughly 2,000 members, [ 5][ 6] making it one of ...
Pressed flower decoupage on a miniature chair. Oshibana (押し花) is the art of using pressed flowers and other botanical materials to create an entire picture from these natural elements. [ 1] Such pressed flower art consists of drying flower petals and leaves in a flower press to flatten them, exclude light and press out moisture.
