blue snake weed. we also know it (i think) as Stachytarpheta jamaicensis
I have seen it planted in at least one herbal gardden in south 24 paraganas in west bengal a few years ago… even though its supposed to be a bit toxic to the liver
do your region have ethnobotanical studies? do tribals in your forest use it?

The Flowers of India site lists Stachytarpheta indica in their pages and call it as “Indian snake weed” and says that it is similar to S. jamaicensis. They further add that it is not clear as to whether the two are same…!

yes, …  all those links that …
has sent if you look at them (i did just now) both are listed in the same listing as if the authors are implying they are synonyms
all snakeweed at east these blue one hybridize like crazy and are according to univ fl extension …difficult to differentiate…
i did not readily find any molecular analysis papers
so may be one has to wait till these weeds find enough interest in the research community
i may yet because it seems it may be an important anti-inflammatory  and may even be useful in diabetes…

Yes …, The possibility of natural hybridisation has compounded the problem of classification and nomenclature. As per my field observation over the years the ones growing in the Eastern plains have off-blue coloured flowers and the ones growing around Ghat forests have deep blue flowers. But I cannot substantiate scientifically….Its only my observation…!

Stachytarpheta jamaicensis for v0-`alidation-GSDEC2016/10 : 3 posts by 2 authors.
I had taken these photographs last year while accompanying … within Bangalore and Chikamagalur in September 2015. Comparison with images images on Flowers of India is even more confusing, but looking at this website and comparison therein (although it considers S. indica as synonym of S. jamaicensis) I place this within S. jamaicensis

Thanks, … I think yes as per http://lee.ifas.ufl.edu/Blue_porterweed.pdf
