Leionema westonii is a flowering plant in the family Rutaceae and is endemic to New South Wales. It has white flowers borne in upper leaf axils.
Leionema westonii is a multi-branched shrub to high and forms a rhizome. The stems are covered with spreading, soft, fine, simple white hairs. The leaves are linear-shaped or narrow elliptic, long, wide, margins rolled under, apex pointed, upper surface covered with spreading, soft, weak hairs, lower surface covered with white, minute protuberances and with sparsely soft, fine, weak hairs. The single flowers are borne in upper leaf axils on a pedicel long, bracteole long and covered with soft, spreading hairs and tapering gradually to a point. The calyx is cup-shaped, long, with occasional long, stiff, upright hairs, sometimes with minute star-shaped hairs, triangular shaped teeth about long. The white petals are long, upper surface smooth, lower surface dotted with glands and with occasional short soft, weak, thin hairs. Flowering occurs from late summer to autumn.[1] [2]
Leionema westonii was first formally described in 2018 and description was published in Telopea.[2] [3] The specific epithet (westonii) honours Peter Henry Weston a co-discoverer of the species in 2004.[3]
This leionema grows in woodland on shallow soils in the Oxley Wild Rivers National Park.[1]
