Selaginella tenera (Hook. & Grev.) Spring is a wild primitive fern from Western Ghats Tamilnadu. 
Yes - the dimorphic sporophylls are just visible. But I wouldn't think of a Selaginella as primitive, really- in many ways they are much more advanced than other groups of Lycophytes as they have developed heterospory. Also the group has radiated greatly in relatively modern times.
