Morphological and Physiological Adaptations of Hydrophytes
Wolffia are free-floating aquatic plants with fronds that are nearly spherical to cylindrical in shape and lack airspaces or veins. They do not have roots. Their rarely seen flowers originate from a cavity on the upper surface of the frond, and each flower has one stamen and one pistil. Although Wolffia can reproduce by seed, they usually use vegetative reproduction. A mother frond has a terminal conical cavity from which it produces daughter fronds. WebRoots absent. Fronds submersed (except when flowering or fruiting), proximal part near surface, 1 or 2–20 or more, coherent, linear, ribbon, sabre or tongue-shaped, or ovate, flat, longer than 2 mm, margins entire; air spaces in tissue; pouch 1, terminal, at base from which daughter fronds (no flowers) originate, triangular, lower wall of pouch with tract of … WebRoots absent.
