It is a bushy shrub with sharply pointed, egg-shaped to elliptic or oblong phyllodes, and yellow-orange flowers with reddish-brown markings.

[2][3][4] Daviesia nudiflora was first formally described in 1844 by Carl Meissner in Lehmann's Plantae Preissianae from specimens collected near Lake Monger in 1839.

[7] In 1995, Michael Crisp described four subspecies and the names are accepted by the Australian Plant Census: This daviesia grows in mallee-heath with a shrubby understorey, and is widespread in the northern half of the wheatbelt, from near Kalbarri to near Lake Grace with disjunct populations near Bunbury and Southern Cross.

nudiflora has about the same distribution as the species, in the Avon Wheatbelt, Coolgardie, Geraldton Sandplains, Jarrah Forest, Mallee and Swan Coastal Plain biogeographic regions of south-western Western Australia.
