The seed micromorphology of all species and subspecies of Orobanche occurring in Sicily has been studied. A synthesis of the results is presented, and comments are made on its taxonomic relevance. In addition, the influence of different hosts on seed size and sculpture has been considered in four species, and intra-individual variation of seed dimensions in four other species has been assessed. Scanning electron micrographs illustrate the seed morphology of 9 species for which no published documents of this kind have been found.
