A pink, tentacled plant kept by Sulu in the botany section of the Enterprise, which recoils and shrieks when the disguised M-113 creature comes near in The Man Trap.
Beauregard is an unusual plant tended by Lieutenant Sulu in the life sciences section of the Enterprise. It appears in The Original Series episode The Man Trap, set in 2266.
Sulu, whose hobby at this point in the series is botany, calls the plant Beauregard, although Yeoman Janice Rand insists on calling it Gertrude. It moves, responds to affection and makes a chiming sound. When Rand brings Sulu his lunch, she is followed in by what appears to be Crewman Green, in fact the shape-changing salt vampire. The plant shrinks back with a squeal, giving the first sign that something is wrong with him.
The plant was realised as a hand puppet. Sulu's botanical interest was soon replaced by other enthusiasms such as fencing and antique firearms.
