Morphology and typification of Szovitsia callicarpa (Apiaceae)

The poorly known monotypic genus Szovitsia Fisch. & C.A.Mey, in the Apiaceae family, is here revised. Szovitsia callicarpa Fisch. & C.A.Mey. is an annual herb with a restricted distribution in the Caucasus region and adjacent areas of northwestern Iran and northeastern Turkey. The genus is unusual within the family because of the transverse plicae covering its fruits. In this study, morphological, micromorphological, and anatomical characters of S. callicarpa are reviewed. In addition, a previous lectotypification of the name S. callicarpa is discussed and amended.
