The flower and the bracts take to two conclusions.
1. B. cristata var. dichotoma. But, in B.cristata var. dichotoma, the leaves
appear bigger than what you have posted in the pictures.
I think this could be somewhere around Barleria nitida. But its distribution
appears to be restricted to South India.
Check for B. nitida. If that is the case it may a unique finding.
We also considered,
1. B. noctiflora, but in this case the corolla tube of B.noctiflora is
2. B. buxiflora, but in B. buxiflora the plant is spinous.
Please check and let us know where u arrive. ;)
