Persoonia muelleri, known as Mueller’s geebung, is a shrub endemic to Tasmania.[1] It forms a shrub in open areas of wet forests in the west and northeast of the state. It is occasionally confused with P. gunnii though it has larger flowers and longer, straighter leaves.
The French botanist Paul Évariste Parmentier described this species as Drimys muelleri, placing it in the family Winteraceae, in 1896.[2] It was given its current name and reclassified in the genus Persoonia by botanist Tony Orchard in 1984.[3] The genus was reviewed by Peter Weston for the Flora of Australia treatment in 1995, and the three endemic Tasmanian species P. muelleri, P. gunnii and P. moscalii are classified in the gunnii group.[4]
There are 3 known subspecies of P. muelleri, which have been also relegated to the rank of variety.[1] Subspecies muelleri has hairless oblanceolate leaves and grows in the northeast of the state. Subspecies augustifolia grows in the west of the state on nutrient poor soils and has narrow, hairy linear to oblanceolate leaves. Subspecies densifolia grows along the south coast and offshore islands and has hairy leaves which are broader than the other subspecies.[5][1]
Populations with characteristics intermediate between P. muelleri and P. gunnii are known from Lake Dove–Cradle Mountain and Adamsons Peak–South Cape localities.[1]
Persoonia muelleri grows as a shrub or small tree anywhere from 1 to 5 m (3–16 ft) tall. It has narrow leaves measuring 1.3 to 6 cm (0.5–2.2 in) long and 0.3–1 cm (0.1–0.4 in) wide. The small flowers are yellow to cream.[1]
Persoonia muelleri subsp. densifolia is known to be susceptible to Phytophthora cinnamomi dieback.[6]
