PUCCINIA SPP. ON ARUNDINEAE IN IRAN: DELIMITATION AND DISTRIBUTION

The taxonomy, morphology and distribution of rust species on Arundineae (Poaceae) in Iran was studied. Five species of Puccinia viz. P. magnusiana Körn., P. phragmitis (Schumach.)Körn., P. isiacae G. Winter, P. trabutii Roum. & Sacc. and P. akiyoshidanensis Morim. are described and illustrated. Of these, Puccinia akiyoshidanensis is considered as a distinct species and newly recorded for Iranian rust flora. Moreover, on the basis of examination of type and authentic materials, P. isiacae, P. trabutii, P. moriokaensis S. Ito and P. okatamaensis S. Ito are considered as distinct species. A distribution map and key to the identified Puccinia species on Arundineae in Iran is also given.
