Derivation. The Greek name for this plant 1s Abrotonon, which 1s variously derived from aéroton, 
incorruptible ; from abrdton, unfit for food ; from the soft delicacy (abrotés) of its appearance ; or 
from abros, soft, and tonos, extension, because it is extended, or grows in a very soft manner. 
Why Linnzus and others write it Abrotanum is not known. The name of Old Man, doubtless, 
has reference to its grey and powdery appearance. It is called Garderobe in French, from its 
being used to prevent moths from getting into clothes-presses and wardrobes. LEberraute is boar’s 
rue ; and Wermuth, wormwood ; Stabwurtz means staff root ; and Gartenwurtz garden root.
