Please identify this herb from Kannur District of Kerala. Leaf midrib underside is slightly spinous..

please see my comment in your id 1 thread

Any idea about the family or genus ?

orchid?

I do not think so.
Cyperaceae family
Family is Cyperaceae.The genus may be Carex.
Now the same plant has grown further with large sized inflorescence. Hope the identification could be easier…

No mix up dear …

Image#….3516 in 1st post is of peduncle and flower buds before blooming.  #…2858 & #…3019 in 5th post are of fruits/seeds images.

I send later the images of whole plant with flowers for a clear view,

Sharing more images.

Probably Juncaceae. Check Luzula nivea or Luzula indica

Does not seem to match with either of these as per POWO specimens:
Also does not match with another species listed in FoPI:
Luzula campestris

Hypolytrum nemorum ?

yes it is Hypolytrum nemorum, thank you very much for ID my plant,  sharing an image,
