Hello Garg ji,
Later on, I do not recollect why I would have dropped the variety ID in my flickr notes. In either case, the post in our group nor the observations in iNaturalist are validated for what I have suggested.
Thus, I am revising my notes for all the observations listed above to Vigna radiata var. sublobata (Roxb.) Verdc. in both flickr and iNaturalist, and will update here, in case it gets validated otherwise.
Many thanks Garg ji, for pointing to the discrepancy in my notes, and the resulting mess.
Regards.
Dinesh
