The Wongan Eriostemon is an erect, multi-stemmed shrub growing to 1 m high with white flowers with pink stripes (Brown et al. 1998; Hopper et al. 1990; Wilson 1982).

This species is only known from the Wongan Hills, approximately 13 km NE of Wongan Hills township, 140 km NE of Perth (Brown et al.1998; Wilson 1982). It was discovered in 1980 and is only known from one area of private land, a few hectares in size (Wilson 1982) There are about 100 plants present (B. Rye pers. comm. in Wilson 1982) and the population is not reserved (Hopper et al. 1990).

This species grows in red sandy soil over fractured schistose greenstone in open Eucalyptus ebbanoensis woodland in laterite capped hills (Brown et al. 1998; Hopper et al. 1990; Wilson 1982).

Flowering occurs from Aug. to Oct. (Brown et al. 1998; Hopper et al. 1990; Wilson 1982).

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.
