Pollen Morphology in L. (Rosaceae) and Its Taxonomic Implications.

The genus L. in the Rosaceae family is taxonomically challenging due to its morphological variation, polyploidy, and interspecific hybridization. In this study, we used scanning electron microscopy (SEM) to observe the pollen morphology of eighty species, representing six subgenera, in order to assess the differences within the genus and its pollen characteristics.
