Pollen morphology and its taxonomical implications – case studies of some alpine-dinaric taxa of the genus Crocus L. (Iridaceae)
The aim of this study was to investigate possible taxonomical and evolutionary significance of pollen morphological features for the genus Crocus. Therefore pollen grains of the some interesting alpine-dinaric taxa of the genus Crocus L. (Iridaceae) were studied by scanning electron microscopy, according to standard palynological procedure (Halbritter 1998). Pollen descriptions follow Hesse et al. (2009). All pollen grains of the genus Crocus are monads and spiraperturate, with mainly echinate and perforate exine ornamentation. Pollen grains are spheroidal and large (51-100 µm), with different and variable number of apertures, which are more or less spiral. Generally, dry pollen grains are circular with sunken apertures. However, several different pollen types were recognized and taxonomically delimited to the specific sublevels. Furthermore, some specific palynological features suggested possible hybridogenous origin of some taxa. Palynological features which could have taxonomical importance on different classification levels are: shape of dry pollen grains ; shape, outline and approximate size of hydrated pollen grains, ornamentation of the aperture membrane and of the exine. Possible taxonomic and evolutionary implications of pollen morphology of the genus Crocus will be suggested and briefly discussed.
