Mimosa

Mimosa ( Mimosa pudica ), as a neophyte in Réunion

The mimosa ( Mimosa ), sometimes referred to as meaning plants are a genus of the subfamily of the mimosa family ( Mimosoideae ) within the legume family ( Fabaceae ). They are mainly located in the Neotropics. Some species are invasive plants in many tropical and marginal tropical countries.

Description

Mimosa species are herbaceous plants, subshrubs, shrubs and small trees. The most thorny stems carry twice pinnate leaves. Mimosa have the option to move their leaves nastisch (plant movement). There are stipules and "minor Papers ", including the leaflets, available.

In the leaf axils, either singly or severally at Blütenstandsschäften little head -shaped or cylindrical -eared inflorescences. The sedentary, relatively small flowers are three to sechszählig, mostly cruciform with double perianth. The petals are fused only at their base. They are all hermaphrodite, or it may Subdiözie be present. The sepals are fused bell-shaped. The most remarkable characteristic of the flowers are free of dust sheets that are each third to sixth in one or two circles and extend beyond the petals. The anthers have no glands. The single carpel contains many ovules. The stylus is thin.

The mostly flat, structured legumes are oblong to linear, membranous to leathery and consist of one-seeded segments, which are separated from each other by edges durable. The flat seeds are elliptical to circular.

Nastien of mimosa

The mimosa is also often referred to as " sensitive plant " because it responds remarkably to external stimuli such as touch. This name is somewhat misleading, since of course a more or less pronounced plant reacts to external stimuli. The plant responds to touch stimuli ( thigmonasty ) on vibration stimuli ( Seismonasty ), violation ( Traumatonastie ), to changes in light intensity ( photonasty ) and air movement with the stimulus direction nonspecific movement of the petiole, the Fiederstrahl and the leaflets ( Nastie ).

Occurrence

The genus Mimosa is predominantly located in the Neotropics. Their habitats include rainforests to dry savannah.

A frequently traded in Central Europe Mimosa species is a native of Brazil mimosa ( Mimosa pudica ), which is usually maintained as an annual ornamental plant, but like all Mimosa species actually is persistent.

In many tropical and subtropical countries different Mimosa species are very unpopular neophytes. These invasive plants are spreading on pastures. Mimosas are not eaten by cattle, because of their movements and the thorns and colonize large areas quickly by rich seed formation.

System

The genus name Mimosa was first published in 1753 by Carl Linnaeus in Species Plantarum, 1, pp. 516-523. Lectotypusart is sensitiva Mimosa Mimosa L. L. Synonyms for are: .

The genus Mimosa belongs to the tribe Mimoseae in the subfamily Mimosoideae within the family Fabaceae (Leguminosae ). There are about 57 similar species-rich genera within the flowering plant; it is estimated the number of species to 530 and continuously new species are described. This diverse genus is divided into sections and series.
