Stenanthemum intricatum is a species of flowering plant in the family Rhamnaceae and is endemic to the southwest of Western Australia.

Description

Stenanthemum intricatum is an erect to spreading, often wiry shrub that typically grows to a height of {{cvt|5–80|cm}}, its young stems sparsely covered with grey or rust-coloured, star-shaped hairs. Its leaves are egg-shaped with the narrower end towards the base, to almost fan-shaped, mostly {{cvt|2–4|mm}} long and {{cvt|1.5–4|mm}} wide on a petiole {{cvt|0.3–1|mm}} long, with broadly triangular stipules {{cvt|1.0–1.5|mm}} long and joined together at the base. The tips of the leaves have three teeth, the upper surface is softly-hairy and the lower surface densely covered with greyish, star-shaped hairs. The flowers are white to cream-coloured, and densely covered with softly-hairy, greyish, star-shaped hairs. The floral tube is up to {{cvt|0.2|mm}} long and {{cvt|0.8–1|mm}} wide, the sepals {{cvt|0.8–1.2|mm}} long and the petals {{cvt|0.6–0.7|mm}} long. Flowering occurs throughout the year, and the fruit is {{cvt|2.0–2.5|mm}} long.{{cite journal |last1=Rye |first1=Barbara L. |title=New and priority taxa in the genera Cryptandra and Stenanthemum (Rhamnaceae) of Western Australia. |journal=Nuytsia |date=1995 |volume=10 |issue=2 |pages=287–289 |url=https://www.biodiversitylibrary.org/item/225398#page/151/mode/1up |access-date=29 December 2022}}{{cite web |title=Stenanthemum intricatum |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%20intricatum |publisher=Australian Biological Resources Study, Department of Agriculture, Water and the Environment: Canberra |access-date= 29 December 2022}}

Taxonomy and naming

Stenanthemum intricatum was first formally described in 1995 by Barbara Lynette Rye in the journal Nuytsia from specimens collected near Kalbarri in 1968.{{cite web|title=Stenanthemum intricatum|url= https://id.biodiversity.org.au/instance/apni/568445|publisher=APNI|accessdate=29 December 2022}} The specific epithet (intricatum) means "entangled", referring to the branching pattern of this species.
