''Draba asprella'' is a [[perennial]] [[herb]] that grows in small, low clumps. At its base, the plant has a thickened stem base called a [[caudex]] with multiple branches. Around each caudex branch, there is a [[Rosette_(botany)|rosette]] of obovate leaves, 0.8–4.5 cm long and 2–12 mm wide, which are sessile or borne on very short [[petioles]]. The leaf margins are typically smooth but may also be minutely toothed. Small hairs called [[trichomes]] cover both the upper and lower faces of the leaves, each 0.2–1.9 mm long; these hairs may be simple or branched, with 2–4 rays. |

The [[inflorescence]] is borne on an unbranched, leafless stem (4–)6–15(–27) cm in length, also covered in simple or 2–4-rayed trichomes. The flowers, typically 30–75 in number, are arranged in a [[raceme]] and are not subtended by bracts. Each flower is yellow, with ovate sepals 1.8–3.5 mm long. The fruit are ovate, hairy, and nearly flat but with inflated bases. |
