Notes. Treated as a distinct species by Alexeev (1982) but as synonymous with F. arizonica Vasey in this database. Alexeev (1982) does not appear to have been aware that specimens of F. arizonica have awns 0.4–1.5(-2.7) mm long.
We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations with detailed captions, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, and distributions of character states within any set of taxa. See also Guidelines for using data taken from Web publications.
