Leionema obtusifolium, is a small shrub with yellow-white flowers in terminal clusters at the end of branches. It is endemic to Queensland.
Leionema obtusifolium is a small shrub to high with a smooth, shiny appearance. The branchlets are flattened with noticeable acute angles and a finely warty surface. The sessile leaves are smooth, papery, narrowly elliptic or with straight sides and rounded apex to spoon-shaped, long, wide, minutely scalloped near the apex that is rounded to blunt. The flowers are a cyme formation of 10-20 flowers at the end of branches on slender stalks long. The sepals are hemispherical shaped, long and the lobes long. The yellowish white spreading petals are narrowly egg-shaped, about long and the stamens more or less equal in length of the petals. Flowering occurs in spring.[1]
This species was first formally described in 1970 by Paul G. Wilson and gave it the name Phebalium obtusifolium.[2] [3] In 1998 Paul G. Wilson changed the name to Leionema obtusifolium and the name change was published in the journal Nuytsia.[4] [5]
This species has a restricted distribution, growing on sandstone hills in the Helidon and Ravensbourne areas of south-eastern Queensland.[1]
Leionema obtusifolium is classified as "vulnerable" by the Government of Queensland Environment Protection and Biodiversity Conservation Act 1999.[6]
