After my posting on Nicandra physalodes, a lot of confusion arose among the respected members. I am not an expert anyway, but watched both the plants closely.
Attaching herewith a PDF document on "comparative study of Physalis minima & Nicandra physalodes".
I have mentioned name of two books at the footnote. It may possible that someone may not have those books in collection. In that case, I may request you the easiest way- go for web photo search to cross-check my identification.
In case of any difficulty in opening the PDF document, kindly let me know, I shall post a word document of the same.
I am sorry, the file is a little bit larger.
