Edinb. 33:434 (1975). Syn: Chrysanthemum heimerlei Náb. in Publ. Fac. Sci. Univ. Masaryk Brno 52:23, t. 1 f. 1 (1925)! Type: Turkey B9 Van: in monte Warak-Dar (Erek Da.) prope Wan, 2600 m, Nábělek 3588 (BRA!). S.E. Anatolia. B9 Van: Şuşanis Da. nr Van, 2200 m, Hub.-Mor. 9026! C9 Hakkari: Kara Da., 2745 m, D. 24324! C10 Hakkari: Cilo Tepe, 3200 m, D. 24071! N.W. Iran. The species belongs to the Irano-Turanian element. T. longi-pedunculatum (Sosn.) Tzvel., which is confined to Soviet Armenia, probably represents yet another variety of T. chiliophyllum. It has very tall stems (c. 45 cm) and bears 8-9 capitula in a loose corymb. |
