本文是一篇基於形態特徵及植物地理學觀點對於印度毛茛屬植物的分類訂正文章，文中共報導了45分類群（包括41種及4變種），包括8個分類群的指定選模式標本。筆者檢視過印度及歐洲蒐藏有採自印度的毛茛屬植物標本的重要標本館及相關文獻，除了發現有16種本屬植物不僅在標本館的標本數量不多，在野外的族群也稀少；本文更處理毛茛屬複雜性較高的物種：禺毛茛(Ranunuculs cantoniensis DC.)、鋪散毛茛(R. diffusus DC.)、R. hyperboreus Rottb.及美麗毛茛(R. pulchellus C.A. Mey.)等與曾被前人處理為同物異名的分類群，在文中都已經被分開為種下分類群或合併到一些物種當中。本文同時包括分種檢索表，每物種詳細的命名資訊（同物異名、模式標本）、分類學描述、親緣關係、物種在印度及世界上的分佈及乾燥標本，並儘可能包含每物種生態學及分類上的意義，且附每一物種的線描圖及細部說明與其在印度的分佈圖。

The genus Ranunculus L. in India is taxonomically revised, based on morphological and phytogeographacial patterns. Forty-five taxa (41 species and 4 varieties) of Ranunculus have been recognized, of these, the taxonomic complexicity among the Ranunuculs cantoniensis DC., R. diffusus DC., R. hyperboreus Rottb. and R. pulchellus C.A. Mey. have been resolved in this treatment, and also several taxa were treated as synonymous to these species by the earlier workers, have been segregated either as infra-specific taxa or were merged under the species proper. Efforts have been made to check and study each and every taxon of Ranunculus known from India, represented in all the Indian and European herbaria and from the literature. Sixteen species of Ranunculus show a very meager representation in the herbaria and in the field as well. The present work also includes the lectotypification of eight species (article submitted for publication). A key to the species, nomenclatural citation of each species, their synonyms, details of type, taxonomic description, phenology, distribution in India and worldwide, exsiccata, ecological and taxonomical notes if any, have been provided. Line drawings of the habit and details of each species have been drawn wherever possible, based on the availability of the materials. The distribution of all the species in India has been shown on the maps.
