From lily, pale, bloodless.(American Heritage® Dictionary of the English Language, Fourth Edition)
The first known use of lily-livered was in 1605. From the medieval belief that the liver was the seat of courage, and the pale color of the lily flower. A person who had no blood in their liver would have no courage and would thus be a coward. (Wiktionary)
