Description
Spyridium scabridum is a slender, erect shrub or small tree that typically grows to a height of up to {{cvt|3|m}} and has densely hairy young stems. The leaves are oblong to narrowly egg-shaped with the narrower end towards the base, {{cvt|5–11|mm}} long and {{cvt|1.5–2.8|mm}} wide on a petiole {{cvt|1.5–2|mm}} long with sticky, egg-shaped stipules {{cvt|3.0–3.5|mm}} long at the base. The edges of the leaves are turned down or rolled under, the upper surface hairy at first, the lower surface felt-like and densely covered with star-shaped hairs. The heads of "flowers" are more or less sessile, {{cvt|5–12|mm}} in diameter and hairy, surrounded by 4 to 7 densely hairy floral leaves {{cvt|4.0–7.3|mm}} long and {{cvt|2–4.3|mm}} wide. Flowering occurs from September to November and the fruit is an oval capsule {{cvt|1.7–2.0|mm}} long.{{cite journal |last1=Kellerman |first1=Jurgen |last2=Barker |first2=William R. |title=Revision of the Spyridium bifidum - S. halmaturinum complex (Rhamaceae: Pomaderreae) from South Australia and Victoria. |journal=Muelleria |date=2012 |volume=30 |issue=1 |pages=43–45 |url=https://www.biodiversitylibrary.org/page/59605029#page/45/mode/1up |access-date=3 November 2022}}
