Description
Mimosa
pigra is a spreading, multi-stemmed, thorny shrub usually
up to 2 m tall, but occasionally up to 6 m, with a maximum lifespan of about 5
years. The plant is evergreen and bears bipinnate, sensitive leaves, up to 18
cm in length. Recurved spines (to 7 mm long) are located on the undersides of
the petioles, petioules and stems. The inflorescences, containing up to 100
flowers, are spherical (about 1 cm across) and pink. The species is
androdioecious with both male and hermaphrodite flowers bearing eight short and
long stamens. These flowers exhibit an intra-specific pollen polymorphism. The
flat pods of M. pigra are hairy and
up to 15 cm long and clustered (up to seven pods) at the stem tips. They
contain between 8 and 24 seeds. Each seed is about 5 x 2.4 mm and weighs 0.09
mg. The fruits ripen in about 3 months and, when mature, fragment into
indehiscent one-seeded segments. The pods are covered with bristles which
facilitate floating and enhance dispersal along river systems (Cabi, 2019).
