摘要
Palynological and leaf epidermal anatomical studies were performed on three Clematis L. species i.e. C. connata DC, C. grata Wall. and C. montana Buch. Ham. in DC using light and scanning electron microscopy. Clematis species usually possess tricolporate pollen but differ in details of polar and equatorial diameter, colpi length, colpi width, exine thickness and exine sculpturing. Anomocytic stomata are present in these species but they differ in details of size of stomatal complex, stomatal aperture, abaxial and adaxial cell length and breadth. Trichomes are present in C. connata and C. grata but absent in C. montana. It is concluded that these three species of genus Clematis are differentiated on the basis of palyno-anatomical characters which are important for correct taxonomic identification of these species along with morphological characters.
