in kenworthys book ''treasure, signs, symbols, shadow and sun signs '' , he makes reference to a sulfide weed that grows where sulfides { like the type emited from silver in the ground } percolate up through the ground.....this weed only grows where these sulfides are present......does anyone know the proper name of this weed, {not maui wowee or kona gold} or can someone post a picture of it.......thanks..........gldhntr
