Mountain steppe and pasture, 800-2400 m. Type: Turkey A8 Gümüşane; d. Bayburt, Kop Dağ, Aşkale-Bayburt, alpine Trift 5 km N der Passhöhe, 1950-2000 m, 28 vi 1951, Huber-Morath 11418 (holo. Hb. Hub.-Mor.!). N.E. & E. Anatolia. A8 Erzurum: 59 km from Erzurum to Ispir, 1900 m, Hub.-Mor. 16139! A9 Erzurum: 14 km from Horasan, 1900 m, D. 29525! B8 Erzurum: Palandöken Da., 20-23 km from Çat to Erzurum, 2300-2350 m, D. 47365! B9 Van: nr. Ber.dimahi 1700 m, D. 44151! Ağri: E. side of Tahir pass, 19 km from Eleşkirt to Horasan, 2400 m, D. 47220! B10 Kars: Karaklisse, 7 v 1916, Schischkin! Endemic; Ir.-Tur. element. A very variable species. Subsp. campylosema is intermediate between subsp. atropurpıtreus and subsp. nigripilis. A. atropıırpureus Boiss. var. rewanduzicus Náb., described without fruit from C8 Mardin: Kurruk Da. nr. Erbil [d. Savur] c. 1600 m, Nábelek 3110, may belong to this species, but in this condition we cannot be certain. A. campylosema var. cappadocicus Boiss. based on a specimen from B5 Kayseri, Erciyas Da., nr. Jachjaila, 1300 m, Kotschy 183, is said to differ from A. campylosema var. campylosema in having a purely white-hairy calyx. The species is related to A. refractus C. A. Meyer, from N. Iran and Soviet Armenia. |
