The Reflexed Everlasting is a shrub growing to 1.3 m high, with slender spreading branches, and cream to yellowish flowers in clusters (Leeson & Rozefelds 2003).

This species is endemic to the Meehan Range in south-east Tasmania and consists of a single population of 4000-5000 plants, restricted to an area of approximately two ha (R. Schahinger, pers. comm. 2001 in Leeson & Rozefelds 2003). Thorough and wide searching in similar habitats to that in which it was discovered has not revealed another population (Leeson & Kirkpatrick 2004).

The single population of Ozothamnus reflexifolius can be clearly differentiated from other species in the genus by its unique leaf characters of strongly reflexed adult leaves. It is restricted to a single valley in the Meehan Range and has probably evolved in situ, being effectively isolated from related species by the surrounding topography.

It is closely related to O. lycopodioides, O. scutellifolius, and O. selaginoides in having conspicuous anauxotelic inflorescences (sections of plants that do not end in a flower or grow beyond the flowering region), capitula in sessile clusters, and leaves with recurved margins (Leeson & Rozefelds 2003).

This species occurs on skeletal soils derived from Jurassic dolerite in three broadly divided vegetation communities. It occurs as an understory shrub in Allocasuarina verticillata-dominated open woodland to closed forest; it is co-dominant in open heath with Spyridium obovatum var. velutinum; and is an important component in rock face vegetation with Dodonaea viscosa, Beyeria viscosa and herbaceous plants including Bulbine glauca, Plantago varia and Thysanotus patersonii. The resurrection fern Cheilanthes austrotenuifolia is present in all community types (Leeson & Rozefelds 2003).

Flowering and fruiting occurs from Nov. to Mar. The plants occur in a region which falls within a rain shadow, receiving approx. 500 mm rainfall/year, therefore, vegetative features, such as long white hairs on seedlings and on new growth close to the ground on mature plants, and waxy covering on adult foliage may be adaptations for survival in drought conditions (Leeson & Rozefelds 2003).

The results of germination experiments shows that O. reflexifolius produces large amounts of viable seed and germinates readily, however it does not appear to have a long period of seed viability (Leeson & Kirkpatrick 2004).

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.
