Sagittaria sagittifolia L. (Alismataceae), known as “arrowhead”, is a stoloniferous aquatic perennial plant with two sorts of leaves: submerged ribbon-like leaves and leaves above the water surface which develop the characteristic arrowhead shape. Ramets grow as a rosette of leaves. The stem is swollen at the base and throws out creeping stolons or runners, which produce winter tubers composed almost entirely of starch. Flowers are pale pink in a spike. The phenotypic plasticity of the leaves of aquatic plants, especiallly that of the Sagittaria sagittifolia leaves, is well known (Haynes & Holm-Nielsen, 1994; Dorken & Barrett, 2003). The plant propagation is mainly asexual through plantlets forming numerous lateral runners. Sagittaria can also be grown from seeds or tubers (Anonymous, 1992). In the literature, some authors describe the morphological characteristics and the foliar dimorphism of this plant (Nyarady, 1966; Tarnavschi et al., 1974; Strasburger, 1991; Bavaru & Bercu, 2002). Information, however, on the anatomy of the vegetative organs of Sagittaria sagittifolia is actually lacking.
