Leaves sessile, linear to filiform, 1-7[-10] × 0.1-0.2 cm, abaxially grayish white and densely arachnoid tomentose, adaxially green and glabrous, margin revolute, apex acute. Capitulum solitary at end of branches. Involucre obconic, 1-2 cm in diam. Phyllaries in 5-8 rows, purplish red, appressed, tomentose, apex not reflexed, acuminate, and cartilaginous; outer phyllaries narrowly ovate-elliptic, 3-5 × 1-1.5 mm; middle phyllaries narrowly ovate to narrowly elliptic, 5-13 × 1.5-2 mm; inner phyllaries broadly linear, ca. 14 × 1.5 mm.

Gravelly riversides, moist gorges, sandy places; 700-1000 m. C Xinjiang [Kazakhstan].
Jurinea pilostemonoides does not differ from J. filifolia, except by the glabrous anther connectives, which, however, can be glabrescent in J. filifolia as well.
Jurinea karategina (Lipsky) O. Fedtschenko, described from Tajikistan and also treated as Pilostemon karateginus (Lipsky) Iljin, is said to occur in Xinjiang as well (G. M. Shen, Fl. Xinjiang. 5: 258. 1999; Iljin, Fl. URSS 27: 711. 1962), but no specimens from China are known. It differs from J. filifolia by its broader, elliptic or oblong leaves, to ca. 10 × 1.5 cm, and by its smaller florets, with a corolla of 1-1.3 cm.
