Weeper

A weeper was an animate, carnivorous plant.

One weeper plant was "Beauregard" (also known as "Gertrude") that was kept aboard the botanical section of the USS Enterprise (NCC-1701) by Lieutenant Hikaru Sulu. It was a three-foot tall, hollow, rooted tube, from which pink flower petals could extend and retract like a grasping hand. The plant would purr in the presence of those it liked, but was capable of shrill, high-pitched cries when frightened.
