Strobilanthus spp in Iruppu, Kodagu, Karnataka:
please find few photos of a Strobilanthus spp with winged stem and petiole; Is it S. ixiocephalus or S. neesianus?
Seen at Iruppu, Kodagu, Karnataka on 30.07.2011

This is Strobilanthes barbatus of Acanthaceae family. Flowers once in 7 years.
I doubt stem of S. ixiocephalus has wings or even quadrangular!
Another distinguishing character for these two species;
stem glabrous - S. barbatus
stem hairy- S. ixiocephalus
I am not familiar with S. neesianus/ (I think S. neesiana).
