Amaranthus blitoides | False Report |  | Unknown |  | Native |  |  |  |  |  |  | Park herbarium has BADL 421 ([NAME]'s number 485) listed as A. retroflexus on herbarium label, therefore on page 13 of Lindstrom 1958 the listing of Amaranthus blitoides is false report. [NAME] has herbarium specimen BADL 422 A. graecizans which is a synonym for A.blitoides and A. albus. Lindstrom 1959 lists A. blitoides as present. Is likely present in the park, but need more evidence to confirm.  BADL 422 was collected 8 miles west of Interior.  BADL 422 collected outside park boundary.

[NAME] put “probably present” since there are no herbarium specimens to verify this.  She wasn’t sure of the reliability of these sources.  She was wary of the Z databases’ A. fruticosas because they had no A. nanas which are more common.  If you go to the right places you can find A.nana and A. canescens pretty easily, so the reviewer was wondering if they might have mixed them up.
