Wild legume at 3600 m above sea level

This looks to me as if it could be a Lathyrus and I would be grateful for some help. Found in the Ecuadorean Andes at 3 600 m by a grassy path through pasture fields

 

Looks good for Lathyrus. Not sure about the species, though. Check if L. bauhinii or L. crassipes occur at that location.

 

Thanks a lot for the confirmation Andrey. I think that L. subandinus may be another strong possibility.
