  • Description

    Description - The original specimens were rather depauperate and the most prominent characters which separate it from P. Hippiana were not noticed by me when I prepared my Monograph of the North American Potentilleae. The plant is much greener than P. Hippiana; the upper surface of the leaves, as well as the pedicels. hypanthium and the calyx, is only slightly silky, not at all tomentose; the cyme in well-developed specimens is more open and flat-topped; and the upper segments of the leaves are decurrent and sometimes confluent, which is never the case in P. Hippiaim. By the latter characters it approaches P. ainbigeiis Greene. From this it differs in the appressed pubescence, the smaller flowers and the less coarsely toothed segments. Baker's no. 390, as represented in the herbarium of the New York Botanical Garden, was named P. anibigcns by Professor Greene, but belongs unquestionably to this species.
