Heterostyly in Goniolimon italicum (Plumbaginaceae), endemic to Abruzzo (central Apennines, Italy)
Abstract
Goniolimon italicum is an endemic species to central Apennines (Italy). Here we provide the first report of heterostyly in this species. Two morphological types were identified: an S-morph with stamen filaments longer than gynoecia, stigmas with a papillate surface and finely reticulated pollen grains with very small spinules (Type B); and an L-morph with stamen filaments shorter than gynoecia, stigmas with a cob pattern and coarsely reticulated pollen grains with small spinules (Type A). Two new locations of G. italicum were found and are here reported.
