The Jerramungup Myoporum is a twiggy spreading shrub growing to 1 m high with solitary white flowers (Robinson & Coates 1995).

This species is found between Ongerup and Jacup, WA (Hopper et al. 1990). It is mainly known from six sites that have been disturbed. Most locations are on road verges, fire breaks or chained bush. The largest population of 10,000+ occurs at Twertup with the smallest surviving population at Corackerup having 10+ individuals (Robinson & Coates 1995).

This species occurs on disturbed (Hopper et al. 1990) loamy-clays which prior to disturbance supported open eucalypt woodland over tall shrubs. At Corackerup NR it occurs scattered through mallee woodland which is occasionally disturbed by sheet flooding over sandy clay (Brown et al. 1998; Robinson & Coates 1995).

This species is probably short lived (around ten years) with seeds which must have longevity of at least thirty years. Chaining and burning is known to stimulate seed germination. Flowering occurs from June to Nov. (Robinson & Coates 1995).

The potential for undiscovered populations, persisting as soil stored seed in other locations, is high (Robinson & Coates 1995).

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.
