Cyanothamnus fabianoides

Cyanothamnus fabianoides is a compact, multi-branched shrub that grows to a height of {{convert|0.3-0.6|m|ft|sigfig=1|abbr=on}}. The leaves are simple, more or less cylindrical {{convert|5-15|mm|in|sigfig=1|abbr=on}} long with a channel on the upper surface and often bunched. The flowers are white, pink or pale blue and are borne singly in leaf axils on a fleshy pedicel {{convert|1-2|mm|in|sigfig=1|abbr=on}} long. The four sepals are fleshy, narrow triangular to egg-shaped and {{convert|1-3|mm|in|sigfig=2|abbr=on}} long. The four petals are broadly elliptic, {{convert|3-7|mm|in|sigfig=1|abbr=on}} long and thickened- glandular along the mid-line. The eight stamens are hairy.{{cite web |last1=Duretto |first1=Marco F. |last2=Wilson |first2=Paul G. |last3=Ladiges |first3=Yvonne Y. |title=Boronia fabianodes |url=https://profiles.ala.org.au/opus/foa/profile/Boronia%20fabianoides |publisher=Australian Biological Resources Study, Department of the Environment and Energy, Canberra |accessdate=11 March 2019}}{{cite book |last1=Corrick |first1=Margaret G. |last2=Fuhrer |first2=Bruce A. |title=Wildflowers of Southern Western Australia |date=2009 |publisher=Rosenburg Publishing |location=Dural |isbn=9781877058844 |page=191}}

This boronia was first formally described in 1904 by Ludwig Diels who gave it the name Eriostemon fabianoides and published the description in Botanische Jahrbücher für Systematik, Pflanzengeschichte und Pflanzengeographie.{{cite web|title=Eriostemon fabianoides|url= https://id.biodiversity.org.au/instance/apni/470770|publisher=APNI|accessdate=11 March 2019}}{{cite journal |last1=Diels |first1=Ludwig |title=Fragmenta Phytographiae Australiae occidentalis.

In 1998 Paul G. Wilson had described two subspecies.{{cite journal |last1=Wilson |first1=Paul G. |title=New names and new taxa in the genus Boronia(Myrtaceae) from Western Australia, with notes on seed characters |journal=Nuytsia |date=1998 |volume=12 |issue=1 |page=150 |url=https://www.biodiversitylibrary.org/item/224909#page/156/mode/1up |accessdate=12 March 2019}} The names have subsequently been changed to reflect the change in the genus name:

• Cyanothamnus fabianoides subsp. fabianoides (the autonym) grows to a height {{convert|0.1-0.3|m|ft|sigfig=1|abbr=on}} and has white petals {{convert|3|mm|in|sigfig=1|abbr=on}} long with a green midrib;{{FloraBase|name=Cyanothamnus fabianoides subsp. fabianoides|id=50115}}
• Cyanothamnus fabianoides subsp. roseus{{cite web |title=Cyanothamnus fabianoides subsp. roseus |url=https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:77211032-1 |publisher=Plants of the World Online |access-date=21 September 2021}} grows to a height of about {{convert|0.3|m|ft|sigfig=1|abbr=on}} and has white petals with a pink midrib.{{FloraBase|name=Cyanothamnus fabianoides subsp. roseus|id=50116}}

Subspecies fabianoides grows in eucalypt woodland between Norseman and the Esperance area but subspecies rosea grows on hillslopes, around granite rocks and undulating plains between Lake King and the Fraser Range east of Norseman.

Both subspecies of C. fabianoides are classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
