Erect herb to 1.5 m high; branches usually glabrous, occasionally sparsely hairy on lower stems. Leaves usually radical and cauline, ovate or elliptic, to 20(–30) cm long, to 4(–8) cm wide, apex acute or obtuse, base attenuate, usually glabrous, sometimes pubescent; petiole to 7(–16) cm long, usually narrowly winged; upper cauline leaves lanceolate to linear, usually sessile. Inflorescences terminal, panicle-like, usually few-branched, pubescent with glandular hairs. Flowers on pedicels to c. 25 mm long; calyx tubular, 6–13(–26) mm long, pubescent, intersepalar membranes usually conspicuous; corolla white, tube 20–55 mm long, mostly 3–5 mm wide at apex of calyx, pubescent, limb 14–35 mm diam., lobes obtuse or notched; stamens unequal, upper 4 filaments to 3 mm long, lower filament 11–16 mm long. Capsule ovoid to ovoid-ellipsoid, 7–12 mm long; seeds mostly reniform or angled, 0.6–1.2 mm long, honeycombed or wrinkled. Flowers mainly spring and summer.

Nicotiana x flindersiensis (a hybrid between introduced Nicotiana glauca and native Nicotiana suaveolens) was named for the type locality, Flinders Peak, in the You Yang ranges near Geelong.
Nicotiana maritima has been recorded from several sites in Victoria (e.g. Studley Park, Cape Schanck), but close examination of herbarium specimens has shown these to be either misidentified, or geographically misplaced (e.g. by misinterpretation of South Australian localities for like-named places in Victoria). The Cape Schanck population is noteworthy for the unusual near-coastal, sandy habitat and for their much hairier-than-typical lower stems and leaves by which they approach N. maritima, but they lack the characteristic leaf shape and floral morphology of that species.
