On 13/9/08 at Vanasthalipuram Deer Park in Hyderabad, AP. I hope the Id is correct.

A reply from another thread:

“you may like to add one more feather in your cap, as proud owner of (most probably) Leucas stricta Wall. ex Benth. Another closely related species is L. clarkei Hook. f.”

Yes Sir, this is Leucas stricta Wall. ex Benth.; terminal whorl subtended by linear bracts as long as calyx, also subtended by leaves; funnel shaped slightly curved calyx tube with subulate acicular teeth.

Leucas hirta (B.Heyne ex Roth) Spreng., erect herb in rainfed agriculture fields, near Krishnagiri, Tamilnadu

Thanks, … But these images look different from Leucas hirta identified by you at Leucas hirta (B.Heyne ex Roth) Spreng. SN Sep 29 & Leucas (Lamiaceae) for ID :: 060115 :: MK007

Yes, it looks different from Leucas hirta 

For me it looks like common L.aspera.  

It may be Leucas aspera.

Looks different from other images at Leucas aspera (Willd.) Link

Also looks different from images at Leucas cephalotes (Roth) Spreng.
