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.
Pennisetum pedicellatum, known simply as desho or as desho grass, is an indigenous grass of Ethiopia of the monocot angiosperm plant family Poaceae. It is also known as annual kyasuwa grass in Nigeria , bare in Mauritania , and deenanath grass in India .
The dicotyledons, also known as dicots (or, more rarely, dicotyls), [2] are one of the two groups into which all the flowering plants (angiosperms) were formerly divided. The name refers to one of the typical characteristics of the group: namely, that the seed has two embryonic leaves or cotyledons. There are around 200,000 species within this ...
In both gymnosperms and angiosperms, the young plant contained in the seed, begins as a developing egg-cell formed after fertilization (sometimes without fertilization in a process called apomixis) and becomes a plant embryo. This embryonic condition also occurs in the buds that form on stems. The buds have tissue that has differentiated but ...
Angiosperms 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. [8] 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.
angiosperm A flowering plant; a plant with developing seeds enclosed in an ovary. anisomery The condition of having a floral whorl with a different (usually smaller) number of parts from the other floral whorls. anisotomic Branching, with branches having unequal diameters, such as a trunk and its branch. Contrast isotomic. annual
Nymphaea alba, from the Nymphaeales. The basal angiosperms are the flowering plants which diverged from the lineage leading to most flowering plants. In particular, the most basal angiosperms were called the ANITA grade, which is made up of Amborella (a single species of shrub from New Caledonia), Nymphaeales (water lilies, together with some other aquatic plants) and Austrobaileyales (woody ...
Monocots are grass and grass-like flowering plants (angiosperms), the seeds of which typically contain only one embryonic leaf or cotyledon. [12] Terrestrial plants evolved perhaps as early as 450 million years ago from a group of green algae. [13] Seagrasses then evolved from terrestrial plants which migrated back into the ocean.
