Asplenium majoricum

''Asplenium majoricum'' is a tiny fern endemic to Mallorca (Serra de Tramuntana) and some locations in Valencia and south of Catalonia. It belongs to the Aspleniaceae family. This allotetraploid hybrid (2n = 144 chromosomes) is the result of crossbreeding between the diploid ferns ''Asplenium fontanum'' subsp. ''fontanum'' (2n = 72 chromosomes) and ''Asplenium petrarchae'' subsp. ''bivalens'' (2n = 72 chromosomes), followed by the spontaneous doubling of the number of chromosomes. Its fronds measure between 6 and . The sori are more longer than wide with a side indusie and are located near the central line of the pinnae. Sporulation from March to November.
== Habitat ==

This small fern lives among the stones of the walls of the terraces and in the crevices of limestone rocks oriented North and Northwest. It likes light but not direct sun. In the dry summer months enters in estivation (summer sleep), dehydrating the fronds until apparently dead. With the first rains of autumn, the fronds will rehydrate in less than 24 hours and turn green as if nothing had happened. A few days starting to sprout new fronds. Stops in the middle of winter to spring, restarting sprouting in the spring.
