plant from North gujarat
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.
please identify it.: 1 image.
Found on mountainous rocks
with elevation of 9000 feet asl, from moist temperate region of Pakistan.
It is a Justicia species.
This is Justicia quinqueangularis J. Koenig ex Roxb. as per images and details herein.
Please check Justicia of your area!
Justicia vahlii Roth !
I think looks different from images at Justicia vahlii
It is Justicia quinquangulare; reason- the stem is 5 angular, hairy, leaves linear, slender.
Please check Justicia notha
to me not matching with J.notha
Justicia diffusa Willd. var. hedyotidifolia (Nees) Clarke ?
I agree with … for Justicia quinqueangularis, as per images and details herein.
