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.
Pl check this: http://en.wikipedia.jpg


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.

Please check Justicia notha
