Dear Saroj ji,
I missed this email. It is albino-flowered (unusual, I have never seen before) Commelina maculata.
C. paludosa and C. undulata has large, rounded, usually lilac or white petals, and acute spathes. Whereas, C. maculata can be sorted by its small, ovate, blue (rarely white) petals and apiculate to acuminate spathes. Although, all the three species often found difficult to recognise in the field, if you are not familiar with key features.
Thank you for sharing.
sincerely,
Mayur
