I know of only two locations for this unusual species. It was first described from chalky limestone
roadside rockcuts outside of the town of Jacala, Hidalgo (Pray, 1967), where it is still locally common
today (at least as recently as August 2009). It is also found (and is also locally common) in the gypsum
outcrops of Municipio San Nicolas Tolentino, San Luis Potosí, which it shares with the extremely local
endemic Pellaea ribae (known from no other location). At the latter site, N. jacalensis plants can be
quite large, approaching N. copelandii in size.

Notholaena jacalensis most closely resembles a small version of N. copelandii , and thus its phylogenetic
position with N. bryopoda and N. neglecta is rather surprising. Interestingly, in the original description,
Pray (1967) suggests that N. jacalensis shares a resemblance with N. greggii (and thus with N. bryopoda
by extension), an observation worth further attention in light of our molecular data. From Notholaena
copelandii it differs in its narrower leaf, more-gradual tapering of the leaf tip, widely spaced segments,
and purported by farina colour (with N. jacalensis having light yellow farina, versus the white farina of
N. copelandii ). However, in the field, the farina colour of N. jacalensis seemed to vary based on
exposure and age, with some individuals distinctly yellowish, and others nearly white. Notholaena
jacalensis also differs from N. copelandii in its rhizome scales, which are smooth, and resemble those of
N. candida. With Notholaena bryopoda and greggii it shares the widely spaced segments, and the slight
narrowing of the bases of the ultimate segments (Pray 1967).

Single-locus chloroplast data (Rothfels unpublished) place N. jacalensis in a polytomy with N. bryopoda
and N. neglecta, well within core Notholaena II.
