Usually much branched shrubs, frequently pachycladous. Stems with tomentum and prominent leaf scars. Leaves usually crowded on current season's growth, entire, tomentose to lanate or felted below, slightly to strongly revolute. Inflorescences of terminal, sessile, syncephalous glomerules subtended by leafy bracts. Heads of 1-20 homogamous, tubular disc flowers, often subtended by bracts; phyllaries imbricate in several series, oblong, obtuse to subacute. Pappus biseriate; inner paleas 4-10 (15) mm long, flattened, twisted, deciduous; outer paleas minute to 2.5 (4) mm long, persistent, sometimes fused basally. Corolla actinomorphic, tube slender, limb narrow. Anther bases sagittate, obtuse to acuminate. Style branches subulate and short hirsute. Achenes cylindrical and slightly enlarged apically, truncate at apex, usually glabrous (but in L. diamantinana strigose apically on the angles), ca 10-ribbed, frequently glandular-punctate between the ribs. Pollen type: an echinate, tricolporate grain with a continuous micropunctate tectum, i.e. Vernonia Type A, sometimes with a tendency towards Type B (Keeley & Jones, 1977). Chromosome number: x = 17.
