Mimosoideae

Mimosoideae (pronunciation: mi-mo-soi-dee-ay) is a subfamily of the flowering plant family Fabaceae or legumes. It is characterized by flowers with small petals and numerous long, prominent stamens that give the flower head a fluffy appearance, often likened to a powder puff or mimosa.

Etymology

The name Mimosoideae comes from the Greek word 'mimos', meaning 'mimic', and 'eidos', meaning 'form or shape'. This is in reference to the flowers of these plants, which often resemble the shape of small mimosas.

Description

Mimosoideae are typically trees, shrubs, or lianas. They are found worldwide, but are most diverse in tropical and subtropical regions. The leaves are usually bipinnate or tripinnate, meaning they are divided into leaflets that are further divided into smaller leaflets. The flowers are small and often fragrant, with numerous long stamens that give them a fluffy appearance.

Genera

The subfamily Mimosoideae includes several well-known genera, such as Acacia, Mimosa, and Albizia. These genera are notable for their economic and ecological importance. For example, Acacia species are used for timber, gum, and tannins, while Mimosa and Albizia species are important in agroforestry and as ornamental plants.
