About the Image

Asplenium aureum Cav. photographed in a remnant of laurel forest in the Barranco del Laurel, Gran Canaria. This species is endemic to the Canary Islands and is the largest within subgenus Ceterach.Molecular data suggest the polyphyly of subgenus Ceterach(Willd.) Bir et al., implicating homoplasy in the lamina shape and the dense scale cover, characters previously used to circumscribe this group.
