Discussion

The venation of Campyloneurum latum is similar to, but more variable than, that of C. phyllitidis.

The only record in the flora is based on a collection by J. J. Soar and A. A. Eaton in December 1903 from Dade County, Florida (A. A. Eaton 1906). Extensive searches at the original collection site and many other likely locations in the southern portions of Florida have failed to turn up any plant that could be called Campyloneurum latum. The species is apparently extirpated from North America north of Mexico.
