Capitulum solitary, in center of leaf rosette or terminal on stem. Involucre bowl-shaped, 1.5-2.5 cm in diam. Phyllaries in 3-5 rows, sparsely arachnoid tomentose; outer and middle phyllaries narrowly triangular-ovate, 5-15 × 1-3 mm, apex spiniform-acuminate and reflexed; inner phyllaries narrowly triangular-ovate to linear, 10-14 × 1-3 mm, apex acuminate and not reflexed.

Jurinea pamirica does not differ from J. algida, except for the stronger branched caudex, which leads to a more densely caespitose or even pulvinate habit. Leaf division is quite variable in J. algida so that this character cannot be used to separate J. pamirica from it.
