Persoonia cordifolia

Persoonia cordifolia is a species of flowering plant in the family Proteaceae and is endemic to a restricted area in the south of Western Australia. It is an erect, rounded to spreading shrub with smooth, mottled grey bark, broadly heart-shaped leaves and bright yellow flowers borne in groups of two to eight along a rachis up to 25 mm (0.98 in) long.

Description

[edit]

Persoonia cordifolia is an erect, rounded to spreading shrub that typically grows to a height of 1–2 m (3 ft 3 in – 6 ft 7 in) with many stems arising from the base and has smooth, mottled grey bark. The leaves are arranged in opposite pairs, broadly heart-shaped, 7–12 mm (0.28–0.47 in) long and 6–13 mm (0.24–0.51 in) wide. The flowers are arranged in groups of two to eight along a rachis up to 25 mm (0.98 in) long that grows into a leafy shoot after flowering, each flower on a pedicel 3–5 mm (0.12–0.20 in) long. The tepals are bright yellow, about 11 mm (0.43 in) long with bright yellow anthers. Flowering occurs from December to January.[2][3][4][5]

Taxonomy and naming

[edit]

Persoonia cordifolia was first formally described in 1994 by Peter Weston in the journal Telopea from specimens collected by William R. Archer near Mount Heywood, 130 km (81 mi) north-east of Esperance in 1991.[4][6]

Distribution and habitat

[edit]

This geebung is only known from the type location and one other 8.5 km (5.3 mi) away, where it grows in heath in the south of Western Australia.[3]
