A diffuse undershrub grows up to 2 meters in height. Leaves bipinnately compound, pinnate 2-4 digitally arranged with 20-30 pairs of leaflets; leaves are touch sensitive. Flowers pink in round heads; fruits bristly pods, flat, consisting 3-5 one seeded segments. Plant is having inwardly curved thorns in all parts.    
MEDICINAL PROPERTIES
Plant is not having any medicinal property. Instead a slow acting poisonous alkaloid called mimosin, which affect Kidney very adversely, leads to renal failure. So by any way the use of this plant should be banned in ayurvedic preparations, as the chance of adulteration by this plant to Lajjalu (Mimosa pudica) is high.
