Pinnae in plane of blade, narrowly deltate-lanceolate to deltate-oblong, narrowed to elongate, serrate tip; basal pinnae deltate-oblong, somewhat reduced, basal pinnules shorter than adjacent pinnules, basal basiscopic pinnule longer than basal acroscopic pinnule; pinnule margins serrate.

Discussion
Dryopteris cinnamomea belongs to the D. patula complex of Mexico and Central America, which is poorly understood. Arizona material of D. cinnamomea has been misidentified as D. patula, according to J. T. Mickel and J. M. Beitel (1988).
Selected References
