Erect to decumbent shrubs or trees 1–5 m tall. Bark lamellose-flaky. Hairs greyish, appressed to patent or curly. Young branchlets moderately to densely hairy. Leaves linear to narrowly oblong to linear-elliptic to linear-spathulate, 2–9 cm long, 1–7 mm wide, flat or convex (often with slightly recurved margins), spreading to suberect, straight, not twisted, innocuous, concolorous to slightly discolorous, not glaucous, sparsely to moderately hairy when immature, glabrescent, smooth. Inflorescence auxotelic, 1–50-flowered; rachis 0–17 cm long. Flowers subtended by scale leaves and leaves; pedicels 2–8 mm long, erect or spreading, moderately to densely hairy; tepals 9–14 mm long, apiculate to caudate, sparsely to densely hairy on outside. Ovary glabrous; ovules 2. 

Occurs east and south of the Great Dividing Range between the northern tributaries of the Macleay River in N.S.W. and Tambo River in eastern Vic. Grows in sclerophyll forest and woodland in well-drained soils derived from a wide variety of substrata, from sea level to 1300 m alt. Flowers chiefly Dec.–May. Map 78.

N.S.W.: Broken Bago Ra., P.G.Richards 48 & P.H.Weston (NSW); 17.1 km NE of Rylstone on road to Growee Gulph, R.G.Coveny 10504 & P.Hind (NSW); Lake Parramatta Reserve, W.Bishop 137 (K, NSW, PERTH); 10 km SW of Candelo, M.Parris 9679 (NSW). Vic.: between Bruthen and Buchan, M.E.Phillips 160 (NSW).

Persoonia linearis hybridises sporadically with P. chamaepeuce , P. conjuncta , P. curvifolia , P. lanceolata , P. levis , P. media , P. mollis subsp. mollis , P. mollis subsp. ledifolia , P. mollis subsp. leptophylla , P. mollis subsp. livens , P. mollis subsp. caleyi , P. myrtilloides subsp. cunninghamii , P. oleoides , P. pinifolia and P. sericea where they grow together. The type of P. lucida R.Br. [Trans. Linn. Soc. London 10: 161, 1810. T: 'In Novae Hollandiae orâ orientali, prope Port Jackson' [N.S.W.], F.Bauer ; syn: BM, E, K] is a P. levis × P. linearis hybrid.

The species shows ecogeographic variation in leaf width. For example, relatively broad-leaved populations (leaves 3–7 mm wide) occur in the upper Hunter River valley, between Merriwa and Denman, in the Gosford district and the area between Lake Conjola and Clyde River. In some areas (e.g. the Gosford district) broad- and narrow-leaved populations occur in close proximity and the variation appears to be ecotypic. However, these variants appear to intergrade.

The locality cited for the type of P. breviuscula ['Qld'] is likely to be an error.
