Suggestions regarding a new variety: 1 very high res. image.
we have found around 5 white flowered specimen of a plant that resambles a plant (Didymocarpus punduanus Wall. ex R.Br. var. pulchrus (C.B.Clarke) Su.Datta & B.K.Sinha ) reported from Sikkim. Most of the plant characters are similar except the flower colour and sparsely pubescent leaves.
