Affinity:— Differs from subsp. subnuda in having longer phyllodes ≥ 10 mm long. Similar to D. debilior

subsp. debilior but the latter has non-pungent fully developed phyllodes that abruptly give way to minute scales part-way up the branchlet, as opposed to the pungent phyllodes of D. hakeoides subsp. hakeoides that gradually reduce in size towards the branchlet tips. Daviesia major differs in having acuminate calyx-lobes, each with a pale stripe, larger flowers (e.g. standard 11–12 mm broad) and a non-turgid viscid pod that lacks a beak. Daviesia smithiorum is vegetatively very similar to D. hakeoides subsp. hakeoides except that the stems are glaucous to pruinose near the base. Daviesia smithiorum also differs in having a pod that is neither turgid nor bluntly beaked and tends to be purplish.
