Heterophylly is rather common among aquatic plants, and is well seen in several aquatic species of Ranunculus, many species of Potamogelon, Sagittaria sagittifolia, Scir pus lacusiris, Castalia (Nymphaea) alba, Hippuris vulgaris, Callitriche spp., Sium latifolium.
Dimorphism or heterophylly is fairly common.
Certain species of the southern hemisphere genus Dacrydium afford particularly striking instances of heterophylly, e.g.
A wellknown fossil conifer from Triassic strata - Voltzia heterophylly - also illustrates a marked dissimilarity in the leaves of the same shoot.
