Family: Mimosoideae / Mimosaceae
Common Name: Makahiya, Bashful Mimosa, Sensitive Plant
Origin: introduced from tropical America
- “The leaflets fold together in the early evening and reopens at sunrise. It is called bashful or sensitive because the leaflets fold together on touching, warming and shaking. The phenomenon is called seismonastic movement due to a rapid change in turgor pressure and changes in membrane permeability in the pulvini cells in the leaf regions with rapid movement of calcium ions. At night, the leaves also fold and bend, termed nyctonastic movements (reaction to absence of light).”
- “When the leaflets fold together on touching, they reopen in about 10 minutes.”
- This is a very common weed in the Philippines and known to most children who love to touch the leaves to make them close!
