look to me as a Striga species –Scrophulariaceae

This is Stachytarpheta X trimeni a Verbenaceae member. This is actually a hybrid species. You can see a detailed nomenclature of this taxon in Revised Flora of Ceylon.

It is not same.

May….Bouchea marrubifolia a member of Verbenaceae.
This plant also reported from our area -Kachchh Arid Zone (Gujarat).

It is not same.

I think … id is correct. New name Chascanum marrubifolium Fenzl ex Walp.
