%X An unusual developmental pattern of stigma was observed in six <em>Clematis</em> species(<em>Clematis tangutica</em>(Maxim.) Korsh., <em>Clematis fruticosa</em> Turcz., <em>Clematis glauca</em> Willd., <em>Clematis gracilifolia</em> Rehd. et Wils., <em>Clematis argenfilucida</em>(Levl. et Vant.) W.T.Wang, <em>Clematis brevicaudata</em> DC.) by scanning electron microscopy. The stigmas of <em>Clematis</em> flowers were on the ventral sides of the styles, and developed into stigmatic papillae by cells along the ventral slits. The shape of papillae change along with the development of stigma. During anthesis, the receptive surfaces matured in a sequence from the apical towards the basal ends of the styles. Stigma development pattern is functionally concerted with other floral design. Our study will be a new field of vision to understand the evolution of stigma in pollen capture with a reference value in breeding and cultivation of ornamental <em>Clematis</em> species.
