Rylstonea cernua R.T.Baker

Homoranthus cernuus is a plant in the myrtle family Myrtaceae and is endemic to a small area in the Wollemi National Park. It is a slender shrub with cylinder-shaped leaves and pairs of cream-coloured flowers with a pinkish base.[2]

Description

Flowers 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 naming

This 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 habitat

Endemic 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 status

Uncommon 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]
