plant from North gujarat
its often procumbent
collected near cultivated field
To me it appears Justicia glauca. wait for others to respond
It may be some other species of Justicia (or Rostellularia?), but not J. glauca.
Key for Justicia in Gamble flora took me to J. quinqueangularis.
In the picture the bracts show distinct scarious margin why not it is a species of Rungia?
The question is valid with respect to scarious bracts.
But this may not be Rungia because the spike is not one sided.
According to the key in Gamble Rungia has one sided spikes.
