Acacia

In total, there are about 750 species of this plant, among which there are evergreen and deciduous trees or shrubs. Under natural conditions, they are most widely represented in the tropical and subtropical latitudes of both hemispheres. By the way, the branches of mimosa so popular in March are nothing but the southern "silver" acacia!

The name Acacia is derived from the Greek word "akis", which translates as "point". And it is not by chance that many species of this plant have thorns: sometimes they are located at the base of the leaves, sometimes the leaves themselves end in spikes.

Acacia leaves look like feathers because of the numerous small leaves symmetrically located on both sides of the central vein. The flowers of acacias are usually not large, collected in a complex paniculate, capitate or spicate inflorescences, usually yellow or white. Fruits are bivalves or non-opening beans. Therefore, data from different sources diverge, it is still not clear to which family does the Acacia belong: legumes or mimosa?

Acacia (erroneously from a scientific point of view) also refers to some trees of the legume family: Karagana (the so-called "yellow acacia") and Robinia ("white acacia").
