The nitrogen-fixing properties of Mimosa pudica contribute to a high nitrogen content within the plant's leaves. The leaves of M. pudica also contain a wide range of carbon to mineral content, as well as a large variation in 13 C values.
Bashful mimosa: Mimosa pudica: Ground cover for tomatoes, peppers: predatory beetles: Used as a natural ground cover in agriculture Caper spurge: Euphorbia lathyris: Moles: Used in French folk medicine as an emetic and purgative [1] Many domesticated animals can eat it, although it is poisonous to humans. [1] Primarily edible Nettle: Urtica dioica
Mimosa pudica in normal and touched state.. In biology, thigmonasty or seismonasty is the nastic (non-directional) response of a plant or fungus to touch or vibration. [1] [2] Conspicuous examples of thigmonasty include many species in the leguminous subfamily Mimosoideae, active carnivorous plants such as Dionaea and a wide range of pollination mechanisms.
The leaves of the sensitive plant, Mimosa pudica, close up rapidly in response to direct touch, vibration, or even electrical and thermal stimuli. The proximate cause of this mechanical response is an abrupt change in the turgor pressure in the pulvini at the base of leaves resulting from osmotic phenomena.
In Mimosa pudica, the internal biological clock mediates the closing of leaflets at night and opening during day. [3] Rapid (seismonastic) movement of leaves is triggered in response to touch and temperature. [4] A pulvinus is located at the base of each leaflet of the plant.
Many of these plants are used intentionally as psychoactive drugs, for medicinal, religious, and/or recreational purposes. Some have been used ritually as entheogens for millennia. [1] [2] The plants are listed according to the specific psychoactive chemical substances they contain; many contain multiple known psychoactive compounds.
The following species in the flowering plant genus Mimosa are accepted by Plants of the World Online. [1] About 90% of its hundreds of species are found in the Neotropics . [ 2 ]
A common example is the curling of Rhododendron leaves in response to cold temperatures. Mimosa pudica also show thermotropism by the collapsing of leaf petioles leading to the folding of leaflets, when temperature drops. [1] The term "thermotropism" was originated by French botanist Philippe Van Tieghem in his 1884 textbook Traité de ...
