From each node, leaves spread horizontally or nearly so on the surface of the water. The exposed side of a floating leaf is actually the lower (adaxial) surface, On the surface of the floating leaf are numerous hairs, each with finger-like branches at the tip, and these hairs are very effective in keeping the leaf surface dry (non-wettable or waterproof) by trapping air, thereby permitting the plant to remain floating and to prevent the stomates from being covered with water. Salvinia, called water spangle or floating fern, has no true roots on the adult plant, but instead has a finely dissected submerged leaf type that appears rootlike.
