Wissadula hernandioides is very uncommon within the flora area, having been reported [as W. amplissima (Linnaeus) R. E. Fries, following Fries (1908)] from only Cameron County, Texas; Collier County, Florida; and Louisiana (unvouchered).
It has been widely but incorrectly referred to Wissadula amplissima. A. Krapovickas (1996) clarified the correct application of the latter name to a different Neotropical species.
