Catharine Parr Strickland Traill, North American Wild Flowers
“ Where there is a deep deposit of mud in the shallows of still waters we frequently find many different species of aquatics growing promiscuously. The tall lance-like leaf and blue-spiked heads of the stately Pontederia, keeping guard as it were above the graceful Nymphæa, like a gallant knight with lance in rest, ready to defend his queen, and around these the fair and delicate white flowers of the small arrow-head rest their frail heads upon the water, looking as if the slightest breeze that ruffled its surface would send them from their place of rest. ”
