Herbs perennial, 15-40 cm tall, hispid, strigose. Stems single or several (1-4) arise from rosettes, caspitose, erect, not branched, usually pale straw to light brown, densely covered with long white spreading bristles. Basal leaves short petiolate, linear to linear-oblanceolate, 10-23 cm
3-10 mm, abaxially densely pubescent and hispid along rised midrib and margin, reticulate venation, adaxially densely appressed hispid and short strigose, base attenuate, apex acute; Cauline leaves sessile, lanceolate, 2-5 cm
1.5-5 mm. Inflorescences terminal, solitary or dichotomously branched, 4-8 cm wide at anthesis, length to 11 cm in fruit, flowers 5-20; bracts lanceolate to linear-oblanceolate, 1.2-2 cm
1-2 mm, densely hispid, short strigose, parted nearly to base; lobes linear. Corolla cream above middle, light yellow below middle, clavate, 2.2-2.7 cm, base ca. 2 mm wide, gradually expanded upward; throat ca. 5 mm wide, obscurely pubescent outside, glabrous inside; lobes broadly triangular, ca. 1.5
3 mm. Filaments subulate, 9-11 mm, decurrent; anthers united only at base, 7-8 mm, included, apex sterile, ca. 2 mm. Style 2.4-2.8 cm, glabrous. Nectary ca. 1 mm, glabrous. Pollen grains isopolar, tricolporate and prolate, polar axis (P) 21.91
