The Wagin Banksia is an erect shrub or small tree growing to 4 m. The flowers are borne in cone-shaped clusters and are red in the lower half, grading to cream above, with the limb pale yellow and all turning orange-brown (George 1988; Hopper et al. 1990; George 1999).

This species is found to the west of Wagin and Katanning, in the southern wheatbelt of south-western WA (Brown et al. 1998). Originally known only from the type locality in Nature Reserve 9098, 28 km north-west of Wagin, where there are about 300-400 plants (George 1988; Taylor & Hopper 1988). By 1999 it was known from two localities near Wagin, WA (George 1999).

Banksia oligantha is closely related to B. cuneata but there are fewer flowers in the inflorescence (George 1988; Taylor & Hopper 1998).

The Wagin Banksia is found amongst otherwise cleared farmland (Taylor & Hopper 1988). It grows in brown and yellow-brown sand along an ephemeral salt creek system in tall shrubland, with Banksia attenuata, B. prionotes, Eremaea pauciflora, Leptospermum erubescens and Conospermum (George 1988; Taylor & Hopper 1988; Hopper et al. 1990). It has also been reported from deep white sands, in areas where it is sometimes the dominant plant (Brown et al. 1998; George 1999).

This species appears to lack a lignotuber and is fire-sensitive, regenerating only from seed. Flowering occurs from Oct. to Nov. (George 1988; Hopper et al. 1990; George 1999).

Follicles open readily even in the absence of fire (Taylor & Hopper 1988).

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
