The Small-leaf Spyridium is a many-branched shrub, growing to 1.5 m high. In open situations it grows as a compact shrub, tending to be more straggling in shaded situations. It has small, thick, leathery leaves 2-4 mm long, and very small cream-coloured flowers clustered at the ends of branches which are surrounded by whitish leaves resembling petels. The flowers are surrounded by conspicuous velvety floral bracts.

Threats The main identified threats to the Small leaf Spyridium are fire and degradation of habitat from weeds; notably Gorse (Ulex europaeus) (TSS; 2009).
Populations on exposed highly isolated sites may be impacted adversely by fire if follow up rains are not forthcoming; as evidenced by the Three Thumbs subpopulation near Orford.

Description of Threats The main threats to the Small leaf Spyridium are land clearance; inappropriate fire regimes; and degradation of habitat by weeds and grazing (TSS; 2006a).
Inappropriate fire and grazing regimes are potential threats which may have an impact on the viability of the populations.
All populations; including those in reserves; are potentially threatened by inappropriate fire regimes.
The Committee considers that the species has a restricted geographic distribution; which is precarious for the survival of the species due to habitat clearance; inappropriate fire and grazing regimes; and the impact of woody weeds.
The impact that land clearance has had on the distribution of potential habitat along the St Pauls; Swan and Apsley Rivers; along with the current threats of grazing and woody weed invasion and the potential threat of inappropriate fire regimes; suggest that the number of plants is likely to continue to decline.
The Committee considers that the species has a restricted geographic distribution; occurring in 10 locations; and an inferred continuing decline in the area; extent and quality of habitat; which is precarious for the survival of the species due to habitat clearance; inappropriate fire and grazing regimes; and the impact of woody weeds.
