中文注释:在田纳西州的里尔夫国家野生动物保护区, 浮萍,这种世界上最小的开花植物生长在这里静止的或者缓慢移动着的湖面上。它长得飞快——有时有些太快了,偶尔会覆盖正片湖面或者近乎干涸萧条的河面上。它保护着那里的水生物,控制过多的矿物质,并且阻止水分蒸发。文字及照片用于国家地理书刊1976年《野生动物的栖息地》一文,未刊发。 作者: Bates Littlehales

Duckweed, the world's smallest flowering plant, grows on the surface of still or slow-moving water. It grows rapidly—sometimes too rapidly, occasionally covering whole lakes or drought-slowed rivers—and provides protection for water creatures, control of excess minerals, and a barrier against evaporation.
