Dear Geeta,
 yes. we had identified it as  Orthosiphon pallidus (O. thymiflorous ). it is abundant  in Sanjay Gandhi National Park.
However while going thr'o the book by Shrikant i found similar flowers (Vol II - page 384), from same Lamiaceae family, which resemble the pics i have uploaded ( e.g. the colour, the quadrangular stem with red tinge). 
I am confused about the leaves. I therefore wish someone to differentiate bet. the two and explain. 
cheers,
shubhada
