Abstract:A species of the genus Delphinium(Ranunculaceae), Delphinium furcatocornutum, is described as new from Sichuan Province. In having sepals with furcate horn-like projections, this species is related to D.campylocentrum Maxim., in which the sepals also bear furcate horn-like projections, and from the latter differs in its 3-parted, abaxially glabrous leaf blades, 3-5 flowers arranged in corymbs, white-puberulous pedicels, slightly downward curved sepal spurs, and not 2-lobulate petals.
