Fern ID - Dimorphic
Perhaps someone here can shed some light on the mystery of this lovely fern I purchased recently. There was no sign with it and though I am pretty good with plant ID, after scouring countless ID sites I just cannot pin it down or come close.
The best I have now is that it is dimorphic (morphologically different sterile and fertile fronds). I provide the following photos as aid. Any help would be hugely appreciated! Thanks guys!

not an expert. However my first thought is that the ‘broad-fronded’ plant has been produced by vegetative propagation from a parent plant that exhibited the unusual characteristics (ferns are very prone to producing these variations).
The fine fronds may be an example of ‘reversion’ as when a variegated holly starts to produce plain green shoots, or may have developed from ‘spores’ from the broad fronds. As it is a ‘sport’ plants from spores will not be the same as the parent plant. The variation can only be propagated vegetatively.
