Sensitive Briar Schrankia microphylla Family Fabaceae This little bean's flowers appear to have been designed by Disney Studios. Who would believe that a natural plant has flowers like neon-pink puffballs, tipped with yellow? Yet, here it is! Flowers and leaves suggest that S. microphylla is closely related to Mimosa (Albizia julibrissin), another exotic-looking bean. Maybe convergent evolution? Leaves of S. microphylla close when touched; thus, its common name.
