Linnaea20: 417. 1847
Phenology: Sporulating summer–fall.
Habitat: Rocky slopes and cliffs, apparently confined to limestone
Elevation: 300–1900 m
Although Notholaena aschenborniana is often described as nonfarinose, the abaxial glandular farina characteristic of all species of Notholaena as defined here is present beneath the dense covering of scales. All individuals examined chromosomally by M. D. Windham (unpublished data) were apogamous triploids that apparently arose through autopolyploidy. Further investigation is necessary to determine whether or not 64-spored, diploid populations of N. aschenborniana are still extant.
