Two New Ferula (Apiaceae) Species from Central Anatolia: Ferula turcica and Ferula latialata

Abstract

Ferula turcicaandFerula latialataare two novel endemic species discovered in the Konya and Kırşehir provinces of the central Anatolian region of Türkiye. These two new species are described by morphological, ecological, carpological, and phytochemical characteristics and phylogenetic analysis. F. turcicaandF. latialataare morphologically distinct fromF. szowitsianaby their habit, the stalk of the terminal umbella, and the mericarp size, as well as by the profile of their secondary metabolite markers and phylogenetic placement. The phylogenetic analyses of sequences of the internal transcribed spacer in ribosomal DNA belonging to both new taxa were conducted to reveal the evolutionary relationships of the new species. Their relationships with the other related species and proposed conservation status were reviewed. The morphological, molecular, and phytochemical evidence supported the hypothesis thatFerula turcicaandFerula latialataare two new distinct species.
