Aubrieta birolmutlui is described as a new species from the eastern part of Turkey based on morphological and molecular
data. The new species is confined to limestone rock and is most similar to A. macrostyla, but it differs by having only
rosette-like basal leaves, larger and entire leaves with sparse indumentum, bigger fruit and short style. The new species is
also close to A. libanotica and A. canescens according to the morphological data. The morphological characters of the new
species distinguishing it from its relatives are given in a comparative table and discussed. This new species, the closest
relative taxa, and some of the Aubrieta species have been studied by sequencing the most commonly used plastid markers in
the genus, namely trnS- ycf9, trnL-F and trnL intron. All the sequences have been evaluated by Maximum Likelihood and
Bayesian approaches and the results support the morphological species delimitation. A detailed morphological description,
photographs from the habitat of the new species, and a phylogenetic consensus tree are provided herein. The new species is
assigned to the CR threat category of the IUCN.
