The Salt Myoporum is an erect shrub growing to 4 m tall, which is at first multi-stemmed and broom-like, but eventually consists of one or a few long slender stems with leafy branches restricted to the uppermost part. Both branches and leaves are sticky and have prominent wart-like protuberances. Flowers are a dull white but often tinged with lilac (Craig & Coates 2001).

This species is known only from road verges over a small range of less than 15 km, north-east of Esperance, WA (Brown et al. 1998; Chinnock 1986).

Myoporum turbinatum is similar to M. platycarpum except for the fruits, which are not as flattened in the latter species (Craig & Coates 2001)

This species grows on the margins of saline depressions in sandy duplex soils (Chinnock 1986), in mallee heath scrub, with Bottlebrushes (Melaleuca), Pincushion Hakea (Hakea laurina) and various eucalypts (Brown et al. 1998).

Flowering occurs in May, and October to February. This species is a disturbance opportunist and relatively short lived (Craig & Coates 2001).

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.
