“…However, other species of aquatic plants that have a triangular petiole (such as some species within the genus Nuphar) have vascular bundles distributed in circles (Sculthorpe, 1967). The pattern of petiole vascular bundles seen in Alismataceae is more similar to that encountered in representatives of the family Hydrochariataceae-with Halophila having a median arc with three bundles, and Hydrocharis and Limnobium having from five to seven bundles (Ancibor, 1979).…”

“…There are a larger numbers of vascular bundles in the arcs and in the abaxial series of E. glandulosus and E. palaefolius than are seen in E. pubescens, E. macrophyllus and S. montevidensis.The vascular bundles in the petioles of Echinodorus are characteristically arranged in arcs, similar to their placement in Hydrocharitaceae (Ancibor, 1979), but differ from that seen in other aquatic plants such as Nymphaeaceae (Conard, 1905) and Hydrostachyaceae (Ja¨ger-Zu¨rn, 1998) where they are disposed in a circular pattern.…”

“…Phenotypic variation is minimal compared to some related species such as Limnobium spongia, which has floating and stranded morphotypes with different leaves (Catling and Dore 1982). For information on anatomy of vegetative organs see Ancibor (1979) and Tomlinson (1982). Aspects of branching are discussed by Loiseau and Nougarède (1963) and Posluszny and Charlton (1999).…”

Catling, P. M., Mitrow, G., Haber, E., Posluszny, U. and Charlton, W. A. 203. The biology of Canadian weeds. 124. Hydrocharis morsus-ranae L. Can. J. Plant Sci. 83: 1001-1016. European frog-bit (Hydrocharis morsus-ranae L.), a free-floating, stoloniferous aquatic, is native to Europe and parts of Asia and Africa. It was discovered in Canada in 1932 in Ottawa, but earlier introduction is possible. By 1955 its North American distribution extended from Ottawa to Montreal. By 1980 it had extended southwest to Lake Ontario and northeast to Quebec City. Recently it has spread throughout much of the central and southwestern parts of southern Ontario, and further into northern New York and Vermont and eastern Michigan. The maximum rate of spread has been 15.6 km yr -1 . Reproduction by seeds is rarely reported but vegetative reproduction is very important in spread and colonization. In the fall, turions separate from the plant, sinking to the bottom where they overwinter. In the spring, these turions grow into small floating rosettes. Extremely rapid stoloniferous growth during the summer months results in the formation of large masses of interlocking plants that diminish native submerged aquatic plant communities by reducing available light. It is also of importance in limiting water flow in irrigation systems and restricting water traffic, thereby hindering recreational activity. Management has been largely mechanical. Hydrocharis morsus-ranae is a food plant for several water birds, rodents, fish and insects.

“…They are also observed in the stem endodermis of several herbaceous and water plants (Esau, 1965;Ancibor, 1979;Fahn, 1990). Typical Casparian bands are found more frequently in underground stems, such as rhizomes than in aerial stems (Fahn, 1990;Lersten, 1997;Morita, 1998).…”
