Discussion Also known as the pale jewelweed. Listed as "of special concern" in Maine. This soft-stemmed annual is less common than the very similar Spotted Touch-me-not (I. capensis). The sensitive triggering of seeds from the ripe capsule inspired these species (as well as the family's) common name, touch-me-not.
Policemans Hat (I. glandulifera), a large, purple-flowered species with mostly whorled or opposite leaves, is found from Ontario east to Nova Scotia and south to Massachusetts.
