The White-flowered Philotheca is an erect branched, spreading shrub or undershrub (Mollemans 1993), growing to 1 m high and 0.8 m wide (Brown et al. 1998).

This species was discovered in 1990 and occurs SSE of Trayning, in the Shire of Trayning, 180 km E of Perth, WA (Mollemans 1993). It is found over a geographic range of only a few kilometres. The two populations, totalling 100 plants, occur on road verges (Brown et al. 1998). The plants were significantly damaged by locusts in 1990 but were found flowering apparently unaffected in 1991 (Mollemans 1993). The species does not occur in a conservation reserve (Briggs & Leigh 1996).

This species grows on deep yellow sand in dense scrub heath vegetation. Associated species include Eucalyptus leptopoda, Grevillea eriostachya, Allocasuarina acutivalvis, Baeckea muricata, B. floribunda, Hakea coriacea, Melaleuca conothamnoides, M. sp., Daviesia sp., Choretrum pritzellii, Phebalium tuberculosum, Pimelea sp. and Hibbertia sp. There is little of this vegetation type left, and what remains is mostly roadside remnants (Brown et al. 1998; Mollemans 1993).

The flowers appear Aug. to Oct. (Brown et al. 1998; Mollemans 1993).

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.
