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: Row 1 : x: 99.5; y: 7.5- 24. Row 2: x: 95; y: 24-14.5. Taxa Notes: Achnanthes minutissima var. saprophila has pronounced large central area on rapheless valve. This form might have been lumped into Achnanthidiu, minutissimum before? Also differenciation beween Navicula tenelloides and N. suchtlandii or N. longicephala in prevoius counts should be studied. Diatom concentration on slide is low, sparse, diatoms often clumped together , makes count difficult!
