  Comment: Stoermer, E. G., R. G. Kreis, Jr. and N. A. Andresen in J. Great Lakes Res. 25(3):515-566: Lange-Bertalot (1980) demonstrated Navicula lanceolata sensu Agardh, Navicula lanceolata Agardh sensu Kütz. Navicula lanceolata Agardh sensu Ehrenb. and Navicula lanceolata Agardh sensu Hust. to be three different species. Navicula lanceolata (C.Agardh) Ehrenb. = Navicula lanceolata(C.Agardh) Ehrenb. Navicula lanceolata (C.Agardh) Kütz. = Navicula trivialis Lange-Bert. Navicula lanceolata (C.Agardh) Kutz. sensu Hust. = Navicula pseudolanceolata Lange-Bert. We could assume the majority of Navicula lanceolata records were identified with either Hustedt (1930) or Patrick and Reimer (1966) which presents problems. Both authors cite (C.Agardh) Kütz. as the authority for the taxon. Patrick states having examined the Agardh type and established a lectotype (Agardh Herb. Lund No. 3401 Frustulia lanceolata Ge.B.A. +4) then gives Kützing as the authority. Adopting the synonymy of Lange-Bertalot (1980)would result in the following: If Hustedt 1930 was used to identify a specimen the synonymy is: Navicula lanceolata (C.Agardh) Kütz. = Navicula pseudolanceolata Lange-Bert. If Patrick and Reimer (1966) was used to identify a specimen the synonymy is: Navicula lanceolata (C.Agardh) Kütz. = Navicula trivialis Lange-Bert. This is unsettling as Patrick in Patrick and Reimer (1966) clearly indicates Pl. 48, fig. 20 as a drawing of the Lectotype. This would mean identifications made using Patrick and Reimer (1966) and citing Pl. 48, fig. 20 represent the Agardh type and should not be considered Navicula trivialis Lange-Bert. which would be the case if one were to just do 'paper taxonomy'
