ground, dried
Sample note
The plant material was collected from Pandukholi Forest, Almora, Uttarakhand (India), and identified according to the Flora of District Garhwal, North-West Himalaya, the Forest Flora of Kumaon. A voucher specimen of B. petiolaris, KRA 24410, was deposited in the departmental Herbarium of CDRI. Each part of the plant (fruit, leaf, root and stem) was washed thoroughly under tap water and dried at room temperature.
