Crotalaria evolvuloides, perhaps.


Further, I would like to clarify few points.
While checking the Kew herbarium (http://apps.kew.org/herbcat/getImage.do?imageBarcode=K000633877) the leaves seems to be entire and obtuse at tip (attaching a cropped picture for closer look).
Here the leaf tip is mucronate and, towards the tip (though, I don’t remember it from the field), it looks like it is slightly serrate. But the specific epithet is apt for its behavior as it looks like Evolvulus (vegetative phase)
Our library is closed as Saturday is holiday for ATREE. I will refer on Monday.


“Thanks for sharing the picture with most of the details of the species.
Now, I feel that the one that I had posted (from Bennarghatta) is different. 


I think appear closer to images at Crotalaria pusilla DC.
