|discussion=<p>We here restrict Pentagramma triangularis subsp. triangularis to plants with yellow farina and glabrous adaxial leaf surfaces occurring throughout a large region in westernmost North America. This subspecies comprises a complex of morphological, cytological, and phytochemical variants, at least some of which may deserve formal taxonomic recognition, following more detailed studies. Plants with yellow farina reported from Arizona, Nevada, and Utah may represent tetraploid hybrids between P. triangularis subsp. triangularis and P. triangularis subsp. maxonii and are not mapped herein.</p>
