Dear TapasThanks for sending the key. Would you let me know which publication this comes from?Would you also please provide an approx. altitude and general location where you took your photos?Such information is important and should always accompany any images of any genus sent foridentification.I do have the key in 'Flora of Bhutan' Vol 1 Part 2 (1984), which covers Sikkim as well but clearly the knowledgeof the genus in the E.Himalaya has advanced since then.One must always use keys with caution. They are difficult to prepare and inevitably imperfect. They canserve a useful purpose in narrowing down the most likely candidates but even so.A major problem is that most are mostly prepared from a limited number of dried, pressed herbarium specimens -the characteristics of living/fresh specimens is often not known by herbarium taxonomists.The detail one can see in photos - not matter how close-up they are (and yours are not) is often inadequateand/or requires inspect of both flowers and fruit, which seldom are available together.

Dear Sir,Thank you.The photograph was taken from a plant near Thangu, North Sikkim at about 4000 m altitude.This key belongs to an unpublished manuscript on the Flora of Sikkim and the family Ranunculaceae is authored by R. C. Srivastava, ex Scientist of Botanical Survey of India.it is indeed well known that the keys to the taxa of certain plant families should be prepared by supplementary field observations as well.Regards,Tapas.

There is a new suggestion - Aconitum laciniatum
Thank you once again Sir.Regards,Tapas.

Dear TapasUnfortunately, this is a challenging genus and requires serious investigation. I have literally dozens of generawaiting for my attention to scrutinize them further. The situation is complicated by me having fewer reference works to-handand less knowledge/familiarity with the flora of the Eastern Himalaya.As to the suggestion A.laciniatum it seems this is no longer an accepted name according to 'The Plant List'. Currentlyunder A.heterophylloides. According to 'Flora of Bhutan' this species is found on grassy alpine slopes and among shrubs @ 3500-4570m in Sikkim & Bhutan.I cannot readily access reliable images or shots of herbarium specimens of this species.Will be in touch when can devote the necessary time and concentration to this or come across a fresh source of information.I see nobody else has volunteered any suggestions.
