\Im*pa"ti*ens\, n. [L., impatient.] (Bot.) A genus of plants, several species of which have very beautiful flowers; -- so called because the elastic capsules burst when touched, and scatter the seeds with considerable force. Called also {touch-me-not}, {jewelweed}, and {snapweed}. {I. Balsamina} (sometimes called {lady's slipper}) is the common garden balsam.
