|description='''Annuals''', 10–50 cm; taproots slender, vertical; caudices small, ± herbaceous. '''Stems''' (1–30), sparingly branched at midstem or distally (lateral branches often short, minutely bracteate or naked), glabrous. '''Leaves''' usually all basal; blades oblanceolate to oblong, 20–110 × 5–30 mm, margins nearly entire to dentate or pinnatifid, faces usually glabrous or glabrate, sometimes hirsute on veins. '''Heads''' borne singly or 2–3 in loose, cymiform arrays (terminating branches, not showy). '''Involucres''' narrowly campanulate, 8–16 × (3–)5–20 mm. '''Phyllaries''' 18–20, lanceolate, 3–18 mm, unequal, margins scarious, faces glabrous (apices brownish or reddish, sometimes ciliate). '''Florets''' 20–40; corollas white to yellowish, 5–8 mm, ± equaling phyllaries at flowering. '''Cypselae''' dimorphic, outer cylindric, stout, truncate, inner fusiform, slender, beaked; bodies dark brown, 10-nerved, 8–10 mm, beaks 3–4 mm; pappi of tawny bristles in 2 series, outer barbellate, shorter than plumose inner, longest 9–10 mm. 2n = 8, 10, 12.

|discussion=Hypochaeris glabra is usually distinguishable by its annual habit and relatively small size, slender and shallow roots, fine stems, often glabrous leaves, and beakless, truncate outer cypselae. Occasional specimens are larger and have induments characteristics of H. radicata; they can be distinguished by the dimorphic cypselae. }}
