Mimosa asperata (M. pigra var. berlandieri, M. berlandieri)

Fabaceae (Leguminosae)

Zarza is a mimosa preferring the seasonal wet areas of clay soils in otherwise dry lake beds and lower areas at the edges of water courses or resacas, usually in the lower Rio Grande in Cameron and Hidalgo counties, and into Mexico. It is less common along the coast farther north. It is a densely-branched shrub forming impenetreble thickets whose branches and leaves are viciously armed with stiff, flattened, recurved prickles. The smooth reddish-brown bark has many lenticils and twigs are slightly pubescent to downy. The 1/2-inch-thick flowers are pink globes.
