Leionema microphyllum, commonly known as limestone phebalium, is a small shrub with terminal clusters of white-pink flowers in spring. It is a rare plant in Victoria and South Australia.
Leionema microphyllum is a small shrub to 40 cm (16 in) high with terete branchlets that are covered with tiny star-shaped hairs or sometimes smooth. The stiff, leathery leaves are egg-shaped to broader egg-shaped, 3–5 mm (0.12–0.20 in) long, 2–4 mm (0.079–0.157 in) wide with an apex almost heart-shaped or pointed to rounded, occasionally smooth or with minute star-shaped hairs with flat, smooth margins. The inflorescence is a cluster of 1-4 flowers at the end of branches in upper leaf axils. The white to pink petals are narrowly egg-shaped, about 4 mm (0.16 in) long and smooth, stamens almost length of the petals. The pedicels are 2–4 mm (0.079–0.157 in) long, fleshy, triangular-shaped lobes are about 0.5 mm (0.020 in) long and smooth. The dry fruit are smooth, about 4 mm (0.16 in) high and the surface finely corrugated with a rounded apex. Flowering occurs in spring. [2]
This species was first formally described in 1855 by Ferdinand von Mueller and gave it the name Eriostemon microphyllus. [3] In 1998 Paul G. Wilson changed the name to Leionema microphyllum and the name change was published in the journal Nuytsia. [4] [5] The specific epithet (microphyllum) is from the Greek microphyllus, micro- meaning "small" and -phyllus meaning "leaved". [6]
