8D4A87C3FFB9FFF5FEFDA248FBC4140A.taxon	discussion	REMARKS Differences between Crataegus pentagyna Waldst. & Kit and C. petrodavisii nom. nov. are as follows and are summarized in Table 1. The leaves of C. petrodavisii nom. nov. are larger than those of C. pentagyna and are glabrous at mature stage. The fruit of C. petrodavisii nom. nov. is bigger than that of C. pentagyna Waldst. & Kit, and it is glabrous. Pyrenes are mostly are 2 - 4 (- 5) for C. petrodavisii nom. nov. whereas they are 4 - 5 for C. pentagyna. Crataegus petrodavisii nom. nov. occurs mostly in forest areas under dry climatic conditions in Iran and Turkey. However, C. pentagyna occurs in more humid deciduous forest and openings. Crataegus petrodavisii nom. nov. is confined to SE Turkey, the ranges of Zagros Mountain and western Iran, it is an Irano Turanian element. However, native range of C. pentagyna is central and southern Europe, Crimea, Caucasia and northern Iran, and it is an Euro-Siberian element (Table 1). Thus, an evaluation of many collections made by the present author, particularly those with flowers or mature fruits, demonstrate that C. petrodavisii nom. nov. is taxonomically distinct from C. pentagyna.	en	Dönmez, Ali A.

Both of the paratypes have been examined by the present author. Christensen & Zielinski (2008) mentioned new material from Tavşanlı, Kütahya which appeared to be an unusual location for this species. The present author therefore undertook extensive field research throughout Turkey and in many localities in Iran, which resulted in the reduction above of this species hybrid to synonymy with C. meyeri Pojark.	en	Dönmez, Ali A.

8D4A87C3FFBDFFF1FEDDA32EFE501488.taxon	discussion	REMARKS Crataegus pseudoheterophylla Pojark. subsp. turcomanica (Pojark.) K. I. Christ. is a first record for the Turkish flora. It grows naturally in mountainous areas of central Anatolia. The examined individuals have plenty of mature fruits. According to the IUCN (2001) criteria, the Turkish population of the species has no threat for extinction. The species is represented by two subspecies and hence an identification key is given here.	en	Dönmez, Ali A. (2014): Nomenclatural, taxonomic and biogeographic novelties in the Turkish Crataegus L.
