subsp. ursina (Kotschy) Browicz, comb, et stat. nov. Syn: P. ursina Kotschy in Verh. Zool.-Bot. Ges. Wien 14:435 (1864); Prunus ınonticola C. Koch var. pııbescens Náb. in Publ. Fac. Sci. Univ. Masaryk Brno 35:107 (1923) !

E. & S. Anatolia. A8 Erzurum: Kop Da., between Aşkale and Bayburt, 2000-2450 m, Rech. 32892 ! B9 Van: E. side of Pelli Da. pass, 38 km from Gevaş to Tatvan, 2240 m, D. 46078 !

C10 Hakkari: 8 km from Şemdinli to Yüksekova. 1700 m, D. 44967 ! W. Syria. A very variable and taxonomically difficult species requiring much further study (for a fuller treatment of infraspecific taxa see Kovalev in Compt. Rend. Acad. Sci. URSS 23. 3:285-291, 1939). Subsp. divaricata is and has long been cultivated for its edible fruit (resembling the Damson) and is probably extensively naturalized. It is probably impossible, however, to distinguish with certainty between truly wild and naturalized populations in Turkey. P. alpestris Schischkin (in Ber. Tomskcr Staats-Univ. 80:472, 1929), described from B10 Ağri (d. Doğubayazit, Klyez -geduk, between Czelkany and Dutach, 24 v 1916, Schischkin; Ağri Da., Achty pass, 11 viii 1916, Supozhnikov & Schischkin) appears from the type description to be no more than a form of P. divaricata with small, glabrous leaves.
