Pimelea holroydii is a species of flowering plant in the family Thymelaeaceae and is endemic to the north of Western Australia. It is an erect shrub with egg-shaped leaves arranged more or less in opposite pairs, and head-like clusters of white or cream-coloured, tube-shaped flowers.
Description
Pimelea holroydii is an erect shrub that usually grows to a height of {{cvt|0.3–1|m}} and has a single stem at ground level. The leaves are arranged more or less in opposite pairs, egg-shaped to broadly egg-shaped, {{cvt|12–37|mm}} long and {{cvt|6–20|mm}} wide on a petiole {{cvt|0.5–2|mm}} long. The flowers are arranged in heads on a peduncle usually {{cvt|5–30|mm}} long, the flowers surrounded by 4 to 7 egg-shaped to broadly egg-shaped, green involucral bracts {{cvt|9–20|mm}} long and {{cvt|7–16|mm}} wide. As the flowers develop, the heads become more elongated. The flowers are usually white, sometimes cream-coloured, each flower on a pedicel {{cvt|0.5–1|mm}} long. The floral tube is {{cvt|2–3|mm}} long and densely hairy, the sepals {{cvt|2.5–3.0|mm}} long. Flowering occurs in January and February and from August to October.{{cite web |last1=Rye |first1=Barbara L. |title=Pimelea holroydii |url= https://profiles.ala.org.au/opus/foa/profile/Pimelea%20holroydii |publisher=Flora of Australia.
