Selaginella ?? 

Best not to bother photographing sterile Selaginella since the strobili are well known to be diagnostic.
Please consult the herbarium in Godavary, just up the road from you, and ask Dr. D.R. Kandl - thus helping you to learn the common species of Nepal.  You may also consult the descriptions etc. In the Checklist of Ferns and Fern Allies of Nepal, vol. 1. 2015 - which will be provided to you free of charge there.  Study in the herbarium is necessary and is the function of a herbarium.

Enclosing some images from the book by Fraser-Jenkings  and the team. Is it one of them?

hopefully Selaginella chrysocaulos (Hook. & Grev.) Spring [vegetative part]
Most probably Selaginella chrysocaulous common in Himalayas including Nepal and Bhutan. Though the diagnostic characters are not in the image.
Sir it seems Selaginerlla chrysocaulos
Thank you ... for the ID !
