\Hen"bane`\, n. [Hen + bane.] (Bot.)
A plant of the genus {Hyoscyamus} ({H. niger}). All parts of
the plant are poisonous, and the leaves are used for the same
purposes as belladonna. It is poisonous to domestic fowls;
whence the name. Called also, {stinking nightshade}, from the
fetid odor of the plant. See {Hyoscyamus}.
