M. Hayne, of Berlin, has observed, that the vesicles at the roots of each species consist of a transparent, 
tough horny, and elastic membrane, and are furnished with an aperture, closed by a lid that only opens 
outwardly. Before the flowers appear, the vesicles are filled with water ; but when the plant brings forth 
the scape, and approaches the time of flowering, the water disappears and air is secreted in them, by which 
means the plant rises to the surface of the water, so that the flowers may unfold in the open air ; when 
the flowering is over, the vesicles are again filled with water, and the plant sinks to the bottom.
