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: 95.5; y: 9.5-17.5 Achnanthes spp. is the same species than what was found in count 410.- need to verify what this is. Extremely hard to differenciate between E.soleirolii and related forms (E. pirla, E. carolina). Decided to keep all in soleirolii, beacause pore size is too big for E. pirla. Pores are very distinct and visible. SEM work might be necessary-also to work on N. wellnerii.
