A new annual Satureja (Lamiaceae) species from Turkey with molecular evidence, and lectotypification of two species

Abstract

A new species, Satureja hasturkii, is described using morphological characters and molecular studies in this study. The new species is closely related to S. hortensis but differs from it by very lax thyrsoid inflorescence, longer pedicels, shorter calyx, upper and lower calyx teeth, and corolla. In order to support the morphological data, molecular studies are also done using nrITS and cptrnL-F gene regions. nrITS data gives better results in phylogenetic analysis. It is pointed out that the closest relatives of S. hasturkii are S. hortensis and S. laxiflora. The fact that having annual life forms of these three species also explain their molecular closeness. With this new species, the number of Satureja species in Turkey increased to 17. Moreover, lectotypes were determined for Satureja macrantha and S. wiedemanniana here.
