Amer. Fern J.5: 1. 1915
Phenology: Sporulating late spring–fall.
Habitat: Rocky slopes and cliffs, on a variety of substrates including granite and limestone
Elevation: 300–2100 m
The low numbers of spores per sporangium in Notholaena standleyi are apparently not associated with apogamy because all plants thus far analyzed are sexual diploids (M. D. Windham, unpublished data). D. S. Siegler and E. Wollenweber (1983) identified three chemotypes in this species correlated with substrate specificity and subtle variations in farina color. These three "races" occupy different portions of the geographic range, and further investigation may indicate that they deserve formal taxonomic recognition. A report of Notholaena standleyi from Nevada (D. B. Lellinger 1985) must be considered suspect because it is disjunct, and the closest populations in Arizona represent a different chemotype.
