The present study introduces two new nothospecies from Turkey, Convolvulus × pseudocompactus C. Aykurt & Sümbül ( C. oleifolius Desr. var. deserti Pamp.× C. compactus Boiss.) and Convolvulus × peshmenii C. Aykurt & Sümbül ( C. holosericeus Bieb. subsp. macrocalycinus Hausskn. & Bornm.× C. compactus Boiss.). Morphological differences and similarities between the hybrids and their parents are discussed; in addition, habit and sepals are illustrated as diagnostic characters, and the geographic distribution of the hybrids and their parents are mapped. Pollen characteristics of Convolvulus × pseudocompactus , Convolvulus × peshmenii and their parents were examined by means of light microscopy and SEM. Detailed morphological and palynological investigations have been performed for hybrid individuals and parental species. As a result of the palynological investigations, the rate of dehydrated pollen grains was established as an important criterion to determine the hybrid status of Convolvulus taxa.
