Discusión taxonómica
(In relation to the synonym Thelypteris mortonii) This is most similar and closely related to T. resinifera, from which it differs in the short-creeping rhizomes and the small indusia that are nearly obscured by sessile, orange-red glands; it also occurs at somewhat higher elevations.A
