Thank you very much Mayur Ji for the ID & keys to *Commelina*. Thank you Garg Sir.
So, it is the same species as in my earlier uploads at https://groups.google.com/d/topic/indiantreepix/d-klP7pd_VY/discussion and at https://groups.google.com/d/topic/indiantreepix/6Xf1XiDWPRE/discussion. As for sizes of spathes i must add that flower sizes also vary, because the flowers in my first upload (in the 1st link) is smaller than the rest. I hope *Commelina diffusa *Burm. f. Fl. Ind. 13. t. 7. f. 2. 1768. is the same as - *C. diffusa*, Burm. Fl. Ind. 18, t. 7, f. 2. as in the attached screenshot of part of F. B. I. vi. 369. or - *Commelina diffusa* N. L. Burman, Fl. Indica. 18, plate 7, fig. 2. 1768. at FoC <http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=222000040>.
