1 QUALIFIER:

  Qualifier Code: TaxaNote
  Description: Notes taken about the taxa for a count; older data typically includes information such as beginning and end scan coordinates, unusual taxa, etc.
  Comments: start x=92.0, y=18.0; end x=92.0, y=10.2 Observations on individual taxa: - In the counts I kept separated dwarf forms of Achnanthidium exiguum var. constrictum. These differ by small size, subrostrate ends, and extremely weak constriction, and might represent a separate taxon. In this count: Achnanthidium exiguum var. constrictum = 116 valves Achnanthidium exiguum var. constrictum DWARF = 2 - In the counts I kept separated typical specimens of Nitzschia palea from a short, subcapitate morphotype. In this count: Nitzschia palea SHORT SUBCAPITATE = 7 valves Nitzschia palea = 1
