Leionema ralstonii

Leionema ralstonii, is a small shrub with angular, smooth branchlets and pale green flowers in winter. It is restricted to the south coast of New South Wales.

Description
Leionema ralstonii is a small shrub to about 1 m high with smooth, substantially angular branchlets. The smooth leaves are sessile, about 30 mm long, 8 mm wide, smooth edges rolled under when dry, papery texture, with a slight notch at the rounded apex. The inflorescence is a tight cluster of 4-7 flowers at the end of branches. The smooth leaves are more or less lance shaped, broader at the apex, 2.5-5 cm long, 5-8 mm wide, gradually narrowing at the base, margins rolled under or upward when dry. The inflorescence is a compact cyme of 4-7 flowers at the end of branches, the stalk bent downwards, individual  fleshy flower stalks are about 3 mm long. The hemispherical calyx is smooth and fleshy with triangular shaped lobes. The flower petals are pale green, about 8 mm long and stamens more than double the length of the petals. The dry fruit sits upright, 4-5 mm long and ending in a short triangular point. Flowering occurs mostly in winter.
