Ophioglossum petiolatum Hook. ???? 
This is Ophioglossum petiolatum. It has a curious habit of invading pots of plants in gardens, and is common on rooftop gardens in Kathmandu, for example - and I hear the same happens elsewhere.  It blows in the wind (I mean the spores do!) and establishes itself.  Nice little thing. Like most or nearly all Ophioglossum species it propagates by root-buds and forms colonies where it has spread to.
Thank you.
