    Type: Turkey, Nigde, in humidis fontiun prope Bulgar Magara, substrato dioritico, 2438 m, 8.1853, Kotschy 285 (Holo-K!).

    B-8 Baltistan: Thalle La, 10000 ft., 13.8.1940, R.R. Stewart 20627 p.p. (RAW), Skardo-Dras, 9100 ft., 18.8.1876, Clarke 30528 (K), B-9 3 km N. of Sankoo, Ladakh, 1980, Southampton University 179 (K), Tibet: Utztachin, Zardkotal, 1838, Herb. Falconer s.n. (K), C-7 Kurram: ascending Sikaram Road, 12000 ft., 4.8.1879, Aitchison 932 (K).

    Distribution: Turkey, Pakistan and Tibet.

    Grows at an elevation of 9-13000 ft., as an annual in dry soil among or near juniper bushes.

    The distribution of this taxon is rather strange as after Turkey, it again makes its appearance in Pakistan and Tibet. Is it really a case of disjunct distribution or hitherto not collaected from Iran and Afghanistan ?
