I think this is from Acanthaceae family 
Please id it
Could it be Dischoriste vagans? just a wild guess!
Can it be Dyschoriste erecta  as per FOI:
It is not Dyschoriste erecta; but it looks like Dyschoriste littorals, not sure for the details are not clear
Does not seem to match with images of Dyschoriste litoralis also.
