C. pseudofoetida described from Altai Mts. is treated here following Kukkonen (in Rech.f.., Fl. Iran. 173: 200. 1998) and understood to contain three subspecies. Plants of Caucasus and Elburs Mts., as well as C. foetida All. var. minor Kük. & Bornm., based on Bornmüller 4801 (B! holotype) from Iran, Kerman (Österr. Bot. Zeitschr. 47: 134, 1897), are considered to belong western C. pseudofoetida Kük. subsp. acrifolia (V. Krecz.) Kukkonen (cf. Dickoré in Stapfia 39: 1-x. 1 298. 1995). Subsp. pseudofoetida occurs in the mountains N of our area; however, also in Pamir and may thus be found in N Pakistan.
