Field Characters

Often confused with Mimosa microphylla and the Netpunias. Mimosa microphylla also has pink flowers but is armed with prickles (M. strigillosa is not). Mimosa strigillosa has a lance shaped stipule which is broadly acute and has no awn while Neptunia spp. have yellow flowers and a stipule that is narrowed at the apex with an awn like extension (Lasseigne 1973).
