Onosmodium
See list of 2 species in this genusOnosmodium bejariense DC. ex A. DC. var. hispidissimum (Mackenzie) B.L. Turner was reported from ME and NH by Turner (1995). The report was certainly in error given that (1) Turner’s manuscript was internally inconsistent (e.g., the identification key gave one range, the discussion of the taxon gave another, the map provided gave yet another range) and (2) no Onosmodium has ever been collected north of MA in New England.
