Abstract
Abstract The pollen morphology of the 16 recognized species of the genus Asphodelus L. (Asphodelaceae) has been investigated by light and scanning electron microscopy. Four pollen types can be distinguished on the basis of variation in size of the polar, equatorial longitudinal and transverse axes, as well as in exine structure and sculpturing, which correlate with the subdivision of the genus into sections. Correlations between pollen size and some biological characters are made. Phylogenetic implications are suggested, and trends of pollen evolution in the genus are indicated.
