Taxonomy and naming

This species was first formally described in 1984 by Norman Byrnes who gave it the name of Darwinia decumbens and published the description in Austrobaileya.[6] In 1991, Lyndley Craven and S.R.Jones changed the name to Homoranthus decumbens.[7] The specific epithet (decumbens) is a Latin word meaning "lying down" or "reclining".[8]

Distribution and habitat

Found in a small area north of Chinchilla Queensland. Grows on deep sandy soils in heath and shrubby woodland on flat terrain.[5]

Conservation

Homoranthus decumbens is listed as "endangered" under the Australian Government EPBC Act of 1999.[4] A very rare species with a highly restricted distribution. A ROTAP code of 2VC is appropriate, Briggs and Leigh (1996). IUCN (2010) considered vulnerable.[5]
