A new genus segregated from Thermopsis (Fabaceae: Papilionoideae): Vuralia

A relict endemic species originating from Turkey, Thermopsis turcica, was excluded from Thermopsis in consideration of morphologic studies based on its flowers and fruits as well as micromorphological features that were obtained by scanning electron microscopy (SEM) and data from supporting molecular analyses internal transcribed spacer (ITS). Additionally, phylogenetic analyses (maximum parsimony and neighbour-joining) were conducted using PAUP 4.0 software. These analyses supported a new taxonomical position for the Turkish species. SEM and morphological studies indicated that the species has unique features that have not been observed in other Thermopsideae species. The unique features and characteristics are comprehensively illustrated here. For confirmation of our purpose, the chromosome number and karyotype of V. turcica were determined via the KAMERAM software program. As a result, all detailed examinations and comparisons of Vuralia and related genera suggest that Vuralia is a new monotypic genus within Thermopsideae, and a new genus and combination nova were established for this Turkish species. © 2014 Springer-Verlag Wien.
