Spreading, multi-stemmed shrub, 2–2.5 m high; branches weeping at tips; bark papery. Leaves lanceolate to broadly lanceolate, mucronate, often slightly asymmetrical, (1.7–)2.2–4.8(–8) cm long, (3–)4–6(–8.5) mm wide, margins thickened, oil glands visible on both leaf surfaces; petiole usually straight. Flower spikes usually with leaf-like bracts at the tip, c. 6–10 cm long, 5–6.8 cm wide; axis hairy; hypanthium hairy; stamens 12–19 mm long, filaments and anthers pinkish-purple. Capsules 5–6 mm long, c. 6–9 mm wide. Flowers mainly Aug.–Nov.

HSF. Known from a single population of c. 10 plants growing along the upper Genoa River.

Callistemon genofluvialis, C. forresterae, C. kenmorrisonii and C. nyallingensis are all quite localised in East Gippsland and are somewhat intermediate between the relatively common and widespread C. citrinus and C. subulatus. These localised species were regarded by Craven (2006; 2009) as hybrid swarms presumably involving C. citrinus and C. subulatus.
