Nuttall’s sensitive-briar

Similar to the sensitive-briar you recently saw from Burnet County is one from an April 27th field trip to Bastrop State Park led by botanist Bill Carr. This time the species is Mimosa nuttallii, known as Nuttall’s sensitive-briar. Here you get a good look at the way the compound leaves of both species close up when something touches them, hence the sensitive part of the name sensitive-briar.
