Cyanothamnus westringioides is an erect shrub that typically grows to a height of {{cvt|75|cm}} and has ascending branches. The leaves are sessile and elliptic, sometimes trifoliate, more or less terete and {{cvt|5-10|mm}} long. The flowers are borne singly in upper leaf axils on a top-shaped pedicel {{cvt|1-3|mm}} long. There are leaf-like bracts about {{cvt|1.5|mm}} long at the base of the flowers. The sepals are prominently glandular, triangular to egg-shaped or pointed and {{cvt|2-3|mm}} long.

Taxonomy and naming
This species was first formally described in 1998 by Paul Wilson and given the name Boronia westringioides in the journal Nuytsia from a specimen collected near the road between Hyden and Norseman.{{cite web|title=Boronia westringioides|url= https://id.biodiversity.org.au/instance/apni/558605 |publisher=APNI|accessdate=15 March 2020}} In a 2013 paper in the journal Taxon, Marco Duretto and others changed the name to Cyanothamnus westringioides on the basis of cladistic analysis.{{cite journal |last1=Duretto |first1=Marco F. |last2=Heslewood |first2=Margaret M. |last3=Bayly |first3=Michael J. |title=Boronia (Rutaceae) is polyphyletic: Reinstating Cyanothamnus and the problems associated with inappropriately defined outgroups |journal=Taxon |date=2020 |volume=69 |issue=3 |pages=481–499 |doi=10.1002/tax.12242|s2cid=225836058 }} The specific epithet (westringioides) refers to the similarity of this species to some in the genus Westringia.
Distribution and habitat
Cyanothamnus westringioides grows on loamy sandplains in a small area north of Lake King and east of Hyden.
Conservation
