Murdannia brownii

Murdannia brownii Nandikar & Gurav;

09-12-09 in Thattekad [Periyar bank], Kerala; Wild Flower for ID-241209-RK-2 - efloraofindia | Google Groups
Plant for ID:   I have confusion with this Plant Murdannia ??? (Commelinaceae
Some of the Morphological charachters shows smillarities with Murdannia pauciflora Wight. But there is an confusion with bearded fertile filaments and habit. 
On the other hand the same species cosidered by Rolla Rao and Kammathy as a Murdannia wightii having glbrous filaments and blue coloured flowers. 
I also search original citation of Robert Wight but it couldn't match with that. 
So anyone can having information about above plant then please reply. 
If it is possible then help me out by providing the original citation M. pauciflora (Wt.) G. Brukner in Engl. & Prantl. Pflanzwenfam. ed. 2. 15a: 173. 1930. M. wightii Rao & Kammathy, Notes Roy. Bot. Gard. Edinburg 25 (2): 184. 1964.
