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: 72.1x95.0 end 112.6=17.1mm Na.tripunct. schizo centered 74.5x95.5 end 112.6=17.1mm Ni. dissipata touch rght margin 75.4x95.5 end 104.5=9.0mm Syn.acus centered Achnanthes minutissima problem in this sample. Three forms or shapes, to me, appear to be present. They also seem to intergrade and I could not accurately separate them, esp in girdle view. 1. normal & typical form, 2, wider w/ narrow rostrate ends 3. wider with slight capitate & wide ends. 2 circles each with a nontypical form scribed.
