it has very leathery thick leaves, texture similar to Microsorum musifolium 'Crocodillus' - but it's not!
the leaves are narrower and more mature leaves develop waves along the edges and then become pinnate.
it has hairy brown feet (rhizomes).
i thought perhaps it is Microsorum punctatum (but not the Elkhorn), since i read that it develops pinnate mature leaves. but images are sort of different from mine.
then i found M. diversifolium - but it has darker central vein and very smooth leaves, while mine is puckered a bit like 'Crocodyllus'
