Stenanthemum pomaderroides is a species of flowering plant in the family Rhamnaceae and is endemic to the southwest of Western Australia. It is an erect shrub with densely hairy young stems, egg-shaped leaves with the narrower end towards the base, and cream-coloured clusters of 10 to 30 tube-shaped flowers.
Description
Stenanthemum pomaderroides is an erect shrub that typically grows to a height of {{cvt|0.2–1.5|m}}, its young stems densely covered with rust-coloured hairs. Its leaves are egg-shaped with the narrower end towards the base, mostly {{cvt|12–18|mm}} long and {{cvt|5–8|mm}} wide on a petiole {{cvt|2–4|mm}} long with egg-shaped or triangular stipules {{cvt|3–6|mm}} long and free from each other. The upper surface of the leaves has star-shaped hairs or is glabrous, the lower surface with shaggy, greyish hairs. The flowers are cream-coloured and borne in clusters of 10 to 30, often with white floral leaves at the base. The floral tube is {{cvt|2.2–4.5|mm}} long and {{cvt|1.0–1.5|mm}} wide, the sepals {{cvt|1.1–1.4|mm}} long and the petals {{cvt|0.7–0.8|mm}} long. Flowering occurs from August to November, and the fruit is {{cvt|2.8–3.2|mm}} long.{{cite web |title=Stenanthemum pomaderroides |last1=Kellerman |first1=Jurgen|last2=Thiele |first2=Kevin R.|editor-last1=Kodela |editor-first1=Phillip G. | url=https://profiles.ala.org.au/opus/foa/profile/Stenanthemum%20pomaderroides |publisher=Australian Biological Resources Study, Department of Agriculture, Water and the Environment: Canberra |access-date= 22 January 2023}}{{FloraBase|id=13476|name=Stenanthemum pomaderroides}}{{cite journal |last1=Kellermann |first1=Jürgen |last2=Thiele |first2=Kevin R. |title=The other ‘propeller plant’ – Notes on Stenanthemum Reissek (Rhamnaceae: Pomaderreae) and a key to the genus in Australia |journal=Swainsona |date=2021 |volume=35 |page=15 |url=https://data.environment.sa.gov.au/Content/Publications/JABG35P011_Kellermann.pdf |access-date=3 January 2023}}

This species was first formally described in 1848 by Siegfried Reissek who gave it the name Cryptandra pomaderroides in Novarum Stirpium Decades.{{cite web|title=Cryptandra pomaderroides|url= https://id.biodiversity.org.au/instance/apni/508169|publisher=APNI|access-date=21 January 2023}}{{cite book |last1=Reissek |first1=Siegrfried |editor-last1=Endlicher |editor-first1=Stephan |editor-last2=Fenzl |editor-first2=Eduard |title=Novarum stirpium decas I-X |date=1848 |pages=29–30 |url=https://www.biodiversitylibrary.org/item/221285#page/37/mode/1up |access-date=22 January 2023}} In 1858, Reissek changed the name to Stenanthemum pomaderroides in the journal Linnaea.{{cite web|title=Stenanthemum pomaderroides|url= https://id.biodiversity.org.au/instance/apni/474200|publisher=APNI|accessdate=22 January 2023}} The specific epithet (pomaderroides) means "pomaderris-like".{{cite book |last1=Sharr |first1=Francis Aubi |last2=George |first2=Alex |title=Western Australian Plant Names and Their Meanings |date=2019 |publisher=Four Gables Press |location=Kardinya, WA |isbn=9780958034180 |page=281 |edition=3rd}}
