Asplenium majoricum

Species of fern in the family Aspleniaceae

Asplenium majoricum is a tiny fern endemic to Mallorca, and some locations in Valencia and south of Catalonia, Spain. It belongs to the family Aspleniaceae. This allotetraploid hybrid is the result of crossbreeding between the diploid ferns Asplenium fontanum subsp. fontanum and Asplenium petrarchae subsp. bivalens, followed by the spontaneous doubling of the number of chromosomes. Its fronds measure between 6 and 12 cm (5 in). The sori are longer than they are wide, with a side indusie, and are located near the central line of the pinnae. Sporulation occurs from March to November.
