Researchers at the CSIR-Institute of Himalayan Bioresource Technology (IHBT), Palampur, have described a new plant species of the sunflower family and named it Doronicum sanctum.
The species was collected in Tawang district of Arunachal Pradesh at an elevation of about 4,086 metres above sea level.
It is the first member of the genus Doronicum, commonly called Leopard's bane, ever documented from Northeast India; all previous Indian records of the genus were confined to the western Himalaya.
The specific epithet sanctum, from the Latin for holy or sacred, was chosen because the type locality lies near the Chumi Gyatse holy waterfalls, a site of spiritual importance to local communities.
The plant carries vibrant yellow flower heads and heart-shaped leaves, and appears to be extremely rare in the wild.

India has four of the world's recognised biodiversity hotspots - the Himalaya, Indo-Burma, the Western Ghats and Sri Lanka, and Sundaland including the Nicobar Islands. Arunachal Pradesh falls within the first two.
One of the largest families of flowering plants, whose 'flower' is in fact a composite head of many tiny florets. Sunflower, marigold, dahlia and Leopard's bane all belong to it.
The westernmost district of Arunachal Pradesh, a high-altitude district on the India-China frontier whose alpine flora remains poorly surveyed.
The place from which the specimen used to formally describe a species was collected; it anchors the name permanently and, here, supplied the epithet sanctum.
