This blue flowered Crotalaria (if I am right upto this  level) was seen near Cherrapunji, Meghalaya during my recent visit to the place.
This is different in leaves and hirsuteness from Crotalaria sessiliflora subsp. sessiliflora i.e. I already have.

Thanks, …  I hope you have already checked in comparative images in efi site. 

Also looks a bit different from images of Crotalaria mairei var. mairei available at http://db.kun.ac.cn/search/list/f/3/t/1/id/49628

May I request you for id of this post, in view of your publication
Crotalaria sessiliflora L.
Thanks, …  But as per …:
‘This is different in leaves and hirsuteness from Crotalaria sessiliflora subsp. sessiliflora i.e. I already have.’

I shall again go through photos and revert back to you.
