Comment:
Stoermer, E. G., R. G. Kreis, Jr. and N. A. Andresen in J. Great Lakes Res. 25(3):515-566: Simonsen (1987) discusses the basis for transferring Eucconeis lapponica Hust. to Achnanthes quadrataera (Østrup) Möller ex Foged. Lange-Bertalot in Lange-Bertalot and Krammer (1989) suggests Achnanthes lapponica (Eucocconeis lapponica) be transferred to Achnanthes laevis var. quadratarea (Østrup) Lange-Bert. in Lange-Bert. & Krammer. Lange-Bertalot also suggested Achnanthes lapponica var. ninckei be transferred to Achnanthes laevis var. ninckei (H. Guermer & Mang.) Lange-Bert. in Lange-Bert. & Krammer. Round, Crawford and Mann (1990) suggested Eucocconeis be considered a valid genus closely related to both Achnanthidium and Cocconeis. We retain the Eucocconeis designation pending further investigation into this little studied, complex group.
