Discusión taxonómica
Hemionitis subcordata is unique in the genus in having 1-pinnate blades and laminar surfaces glabrous. In Colima this has been found to cross with Cheilanthes skinneri (see Hemionanthes). The sori are so different in these two species that it raises the question of usefulness of sorus type as a measure of relationship in this group. See Mickel (1987).A
