Physical Description

Family Mimosaceae:

The Mimosaceae are mostly tropical and subtropical trees and shrubs comprising about 40 genera and 2,000 species. The leaves are nearly always alternate, stipulate, and bipinnately compound (rarely once-pinnate) They usually have swollen petiole bases called pulvini that commonly function in orientation of the leaves (remember the sensitive plant, Mimosa pudica). The inflorescence is commonly a capitulum (also called a head). The flowers are hypogynous to slightly perigynous, have radial symmetry, petals that are valvate in bud, and commonly a 5-parted calyx and corolla. The stamens are distinct to strongly monadelphous, numerous (rarely as few as 10), and are generally more showy than the perianth. The pistil is simple, comprising a single style and stigma, and a superior ovary with 2-many marginal ovules in a solitary locule. The fruit is usually a legume. -- Gerald Carr

Subfamily Mimosoideae:

Mostly trees or shrubs. Leaves mostly bipinnate. Corolla usually not showy, actinomorphic, sympetalous, the lobes valvate. Stamens 10-numerous, often monadelphous, showy. Pollen released in monads, tetrads, or polyads. Seeds with u-shaped line (pleurogram) present. [Carr]
