Capitula ovate-conical, slightly
arachnoid
, 2.5-3 cm in diameter, (without acidotus) monocephalous. Phyllaries are numerous in number 90-100, except internal, with a slightly arcuately reflect acidotus; internal protruding up, lanceolate; scarious on top, acerous in a very thin, short the barb, usually brownish; setula receptacle above advanced, asperous. Corolla pink. Achenes ca. 3.5-4.0 mm long, obovate, glabrous and smooth.

Flowering from June to July, fruiting from July to August.
Habitat.
On the rubbly-fine earth slopes, shale rocks in the middle belt of mountains.

Previosuly considered endemic to the Western Tien Shan Mountains to distribution in Chatkal, Fergana, Uzunakhmat and Atoynak ranges. This range is now extended to the Alay Range, Uzbekistan (Fig.

Species recognition.
Very close to the
Cousinia margaritae
Kult., differing mainly by the color of the corolla (from
Cousinia margaritae
corolla whitish or pale yellow in
Cousinia waldheimiana
corolla pink or purple). However, color of the corolla in the herbarium of poorly stored, making difficulties to define plant, why the geographical boundary of these species are currently unclear (Tscherneva 1962).
