原生地・分布（英語）:

説明（英語）: Genus of about 400 species of annuals, evergreen perennials, shrubs (which are sometimes scandent or trailing), and small trees, found in habitats ranging from forest to dry savannah in tropical regions worldwide. The often spiny stems bear alternate, 2-pinnate leaves, which in some species are sensitive to touch. Tiny, pea-like flowers, each with 4 or 5 petals and up to 10 long stamens, are lightly clustered in spherical heads, which are borne singly, or in spikes or panicles. The seed pods are sometimes twisted, curled, or spiny. In climates where temperatures fall below 13-16°C (55-61°F), grow in a warm greenhouse or as houseplants. In warmer areas, grow the annuals and perennials as ground cover, the shrubs in a border, and the trees as specimen plants. Long, hot summers are required for the production of flowers and fruits. (For the yellow-flowered florists’ mimosa, see Acacia dealbata.)
