Any fern?

this is Selaginella sp. but could not close in into the specific ID.

---

Well the Selaginella is young plants of the well known S. monospora that grows in huge quantity around Darjeeling, E. Nepal etc., but as there is no close-up of fertile strobili, the characteristic diagnostic features are not shown.  All Selaginella requires to show the strobili in detail – to make a more useful photo.
The uncurling frond also shows no diagnostic features, but would presumably be Dennstaedtia zeylanica (syn. D. scabra), if a mature frond were shown.
