Male and female flowers are borne on separate plants.
Description
Pimelea serpyllifolia is an erect shrub that typically grows to a height of 0.1–1.5 m (3.9 in – 4 ft 11.1 in), but is rarely stunted or prostrate in exposed positions. The leaves are borne in opposite pairs on glabrous stems and are crowded, narrowly elliptic to spatula-shaped, 4–12 mm (0.16–0.47 in) long and 2–4 mm (0.079–0.157 in) wide. The leaves are glabrous, and the same shade of green on both sides. The flowers are borne in compact heads of 4 to 12 yellow, yellowish-green or white flowers surrounded by 2 or 4 sessile, elliptic involucral bracts 2–6 mm (0.079–0.236 in) long and 1–4 mm (0.039–0.157 in) wide, female and male flowers borne on separate plants. The floral tube of female plants is 1.5–2.5 mm (0.059–0.098 in) long, the sepals 0.8–1 mm (0.031–0.039 in) long, and of male plants 1.8–2.5 mm (0.071–0.098 in) and 1.0–1.7 mm (0.039–0.067 in) long respectively.
Taxonomy

Why this record matters
“Pimelea serpyllifolia” is worth following because a concise public description often conceals a longer documentary argument. Here, Pimelea, serpyllifolia and species provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 5, 2026. The linked authority identifier is Q7194618. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1810.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
