It is a slender shrub with cylinder-shaped leaves and pairs of cream-coloured flowers with a pinkish base.[2] DescriptionFlowers and fruits sporadically throughout the year but primarily in spring and summer. This species is closely related to H. darwinoides but has longer leaves and larger flowers.[3] Taxonomy and namingThis plant was first formally described in 1889 by Richard Thomas Baker who gave it the name Rylstonea cernua from a specimen collected from Mount Coricudgy. The description was published in Proceedings of the Linnean Society of New South Wales.[4][5] In 1991 Lyndley Craven and S.R.Jones changed the name to Homoranthus cernuus.[6] Distribution and habitatEndemic to the north-western section of Wollemi National Park in central New South Wales. Grows on shallow sandy soils in layered woodland or heath, usually on steep rocky terrain.[3] Conservation statusUncommon and restricted in distribution, but well reserved in Wollemi National Park. Listed as a rare species by Briggs and Leigh (1996) with a ROTAP conservation 2RCa.[3] References1. ^1 {{WCSP | 100138 | Homoranthus cernuus }} 2. ^{{cite web |last1=Harden |first1=Gwen J. |title=Homoranthus cernuus |url=http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Homoranthus~cernuus |publisher=Royal Botanic Garden Sydney |accessdate=23 August 2018}} 3. ^1 2 {{cite journal |last1=Copeland |first1=Lachlan M. |last2=Craven |first2=Lyn A. |last3=Bruhl |first3=Jeremy J. |title=A taxonomic review of Homoranthus (Myrtaceae: Chamelaucieae) |journal=Australian Systematic Botany |date=2011 |volume=24 |issue=6 |pages=351 |doi=10.1071/SB11015}} 4. ^{{cite web|title=Rylstonea cernua|url=https://id.biodiversity.org.au/instance/apni/535255|publisher=APNI|accessdate=23 August 2018}} 5. ^{{cite journal |last1=Baker |first1=Richard T. |title=Supposed new genus of the N.O.
