Asplenium arcanum is a fern found in western Mexico and Nicaragua. It has fibrous roots and an upright rhizome with narrow, blackish scales. The fronds grow in clumps and are 7 to 20 centimetres long, with stipes that are dark purple in color at the base and become green towards the blade. Each leaf bears from one to five pairs of pinnae, with the pair closest to the base being the largest. Fertile fronds bear from one to three pairs of sori per pinnule on both sides of the costule, which are covered by indusia 2 to 5 millimetres long and 0.5 to 0.8 millimetres wide, with jagged margins. The spores are kidney-shaped. It is similar to other species such as A. fragrans, A. minimum, A. pumilum, and A. tenerrimum, but differs in various ways. It grows on stream banks and on wooded hillsides in the states of Nayarit and Sinaloa, at altitudes from 200 to 700 metres.
