Leionema sympetalum, commonly known as Rylstone bell,[2] is a shrub with greenish-yellow tubular flowers in small terminal clusters at the end of smooth, angular branches. It has a restricted distribution, grows near Rylstone in New South Wales.

Description

Leionema sympetalum is a small shrub to 2–3 m (6 ft 7 in – 9 ft 10 in) high with smooth, angular branches covered with star-shaped to minute, soft, upright hairs when young. The leaves are wedge shaped to elliptic 1.5–3.5 cm (0.59–1.38 in) long, 4–8 mm (0.16–0.31 in) wide, smooth, edges slightly recurved, mostly more or less finely toothed when dry, a prominent midrib on the underside and a blunt apex with a slight notch. The inflorescence is cluster of 1-3 flowers often pendulous at the end of branches, each on a slender, reddish stalk about 7 mm (0.28 in) long. The calyx are hemispherical, smooth, fleshy with wide-triangular lobes about 1 mm (0.039 in) long. The flowers are tubular, 10–15 mm (0.39–0.59 in) long, greenish yellow, petals splitting toward the apex turning upward with triangular tips and the stamens longer than the petals. The fruit are a capsule, each segment about 4 mm (0.16 in) high, ending with a short beak. Flowering occurs from winter to spring.[2][3]
