Changes to Potentilla s.l.(Rosaceae) in Flora Iranica

As a summary of independent investigations by multiple authors, numerous updates are now required for the 1969 treatments of Potentilleae (Rosaceae) in "Flora Iranica". Following the convergence of morphology-based conclusions by Soják and molecular phylogenetic analysis by ERIKSSON et al., several sections of Potentilla L. are now treated as segregate genera. Potentilla sect. Fruticosae (Th. Wolf) Gross. becomes Dasiphora Raf., with D. dryadanthoides Juz. replacing P. phyllocalyx (Juz. Schiman-Czeika. Potentilla sect. Bifurcae (Th. Wolf) Grossh. becomes Schistophyllidium (Juz. ex Fed.) Ikonn., with the single species S. bifurcum (L.) Ikonn. replacing P. bifurca L. Potentilla sect. Xylorhizae (Th. Wolf) Schiman- Czeika becomes Tylosperma Botsch, encompassing P. lignosa Willd. (as T. lignosa [Willd.] Botsch.) and P. sericophylla Parker (combination in Tylosperma ined.). Potentilla sect. Rupestres (Th. Wolf) Grossh. becomes Drymocallis Fourr. ex Rydb., with D. poteriifolia (Boiss) Soják replacing P. poteriifolia Boiss. Two other species of Drymocallis are added to the flora: D. rupestris (L.) Soják and D. schiraziana (Khat.) Ertter & Attar, the latter a new combination provided for P. schiraziana Khat. In addition, Comarum salesovianum (Stephan) Bunge is replaced by Farinopsis salesoviana (Stephan) Chrtek & Soják. Additions to Potentilla s.s. include P. discipulorum Davis, P. virgata Lehm., P. alexeenkoi Lipsky, P. agrimonioides M.-Bieb., P. bactriana Soják, P. parmirica Th. Wolf, P. pamiroalaica Juz., P. gorganica Soják, P. laciniosa Waldst. & Kit. ex Nestl., P. botschantzeviana T.A. Adylov, P. ghazniensis Soják, P. porphyrantha Juz., P. algida Soják, P. doubjonneana Cambess., P. crantzii (Crantz) Beck ex Fritsch, and P. adenophylla Boiss. & Hohenack. Among other changes are the inclusion of P. straussii Bornm. within P. speciosa Willd., P. canescens Besser within P. inclinata Villars., P. gilanica Th. Wolf and P. adsharica Sommier & Levier within P. divaricata DC., and P. cryptophila Bornm. within P. petraea Willd. The inclusion of P. argyrophylla Wall. ex Lehm., P. hirta L., and P. tephroleuca Th. Wolf in Flora Iranica is probably erroneous and based on other species.
