Madhuri ji your posted pictures First* Commelina bengalensis 1.jpg *is
absolutely no doubt *Commelina benghalensis *
But *Commelina bengalensis 2.jpg *may be *Commelina diffusa *(most
probably)
May be this key will be helpful to identify few common Commelina's* *in
field .................
1. Spathes with margin free to base
........................................................... *C. diffusa *
1. Spathes with margins fused at least basally
.......................................................2
2. Inflorescence (Spathe) solitary, axiallary or
terminal.........................................3
2. Inflorescence composed of several aggregate, axillary or terminal
spathe...........4
3. Flowers
white...........................................................................
*C. suffruticosa *
3. Flowers
blue.............................................................................................5
5. Spathe funnel shaped...
......................................................*C. benghalensis *
* *5. Spathe broadly
ovate...............................................................*C.
forskalaei*
