Brasenia schreberi - Water shield Floating-leaved plant can be distinguished from the water lilies by its oblong-shaped leaf with complete leaf margin (no nicks or cuts or pie-shaped wedges missing) and stalk which attaces at the center of the leaf. There is often a gelatinous sheath around stalk and underside of leaf. Rarely blooms with small pink emergent flower.
