This is Mimosa pudica, Sensitive Plant. It was probably introduced to Hawai'i in the 1850's, either as a curiosity or accidentally with cattle feed. Ironically, it is poisonous to cattle.
This weed makes meter tall thickets of thorned brambles that hang onto you as you walk by; their recurved thorns make you bleed if you try to pull away from them!
