How to tell the difference between soloman's seal

Whats the best way to tell the difference between soloman's seal and false soloman's seal? In pictures they look pretty much the same to me?

false solomans has more of a woody and crooked stem and leaves are offset
......reg solomans is straight and fleshy with leaves lining up side by side

Solomon's seal has flowers and berries on the underside while false Solomon's seal has flowers at the end of the stem. If anyone is collecting, I need 150 lbs of true Solomon's seal root.
