P. Kumar: I think this is a new species: petals are much shorter than sepals (almost same in O. difformis), outer wall of the stigma is glabrous (papillose in O. difformis), stigmatic wall is narrow and nor extending out (O. difformis wall is much wider), and of course the fringes are very short (much longer in O. difformis).
