Thank you very much for sharing the link, flowers are very matching, but having difference in peduncle image,
Very close to S. anaimudica, but not basally bulbous stem which showing in the diagram,
Could not find a match as per comparative images at Sonerila
I tried with listed species in Flora of Peninsular India, with distribution in the area.
 But could not find any match.
 It comes somewhat close to Sonerila grandiflora, but not convinced.
