Two new hybrid species of Salvia (S. × karamanensis and S. × doganii) from Turkey: Evidence from molecular and morphological studies

Salvia L. is an ideal exemplar to demonstrate prezygotic isolation mechanisms in sympatric populations due to their wellknown staminal lever mechanism. Mechanical, phenological, and ethological isolation mechanisms have been reported among sympatric species of Salvia. However, it has been shown that if closely related species are sympatric and flower at the same time, they can potentially hybridize. In this study, we describe two new hybrid species of Salvia (S. × karamanensis Celep & B.T.Drew, and S. × doganii Celep & B.T.Drew) from Turkey based on morphological and molecular evidence.
