''Persoonia muelleri'', known as Mueller’s geebung, is a shrub endemic to Tasmania. 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. It was given its current name and reclassified in the genus ''Persoonia'' by botanist Tony Orchard in 1984. 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. There are 3 known subspecies of ''P. muelleri'', which have been also relegated to the rank of variety.〔 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.〔 Populations with characteristics intermediate between ''P. muelleri'' and ''P. gunnii'' are known from Lake Dove–Cradle Mountain and Adamsons Peak–South Cape localities.〔 ''Persoonia muelleri'' grows as a shrub or small tree anywhere from tall. It has narrow leaves measuring long and wide. The small flowers are yellow to cream.〔 ''Persoonia muelleri'' subsp. ''densifolia'' is known to be susceptible to ''Phytophthora cinnamomi'' dieback. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Persoonia muelleri」の詳細全文を読む スポンサード リンク
