Eucalyptus lansdowneana
Template:Short description Template:Speciesbox
Eucalyptus lansdowneana, commonly known as the crimson mallee or the red-flowered mallee box,[1] is a species of slender stemmed, straggly mallee that is endemic to a restricted area of South Australia. It has rough, fibrous or flaky bark at the base, smooth, grey over creamy-white bark, lance-shaped adult leaves, flower buds in groups of seven, crimson flowers and barrel-shaped fruit.
Description
Eucalyptus lansdowneana is a mallee that typically grows to a height of Template:Cvt and forms a lignotuber. It has about Template:Cvt of rough, fibrous or flaky bark at the base, smooth, grey over creamy-white bark that is shed in short strips above. Young plants and coppice regrowth have broadly lance-shaped to egg-shaped leaves that are Template:Cvt long and Template:Cvt wide. Adult leaves are glossy green, lance-shaped, Template:Cvt long and Template:Cvt wide on a petiole Template:Cvt long. The flower buds are arranged on both branched peduncles Template:Cvt long on the ends of branchlets each branch with a group of seven buds and on unbranched peduncles in leaf axils, the individual buds sessile or on pedicels up to Template:Cvt long. Mature buds are oval, Template:Cvt long and Template:Cvt wide with a conical to rounded operculum. Flowering mainly occurs between August and October and the flowers are crimson, ageing to pink. The fruit is a woody barrel-shaped capsule Template:Cvt long and Template:Cvt wide with the valves below rim level.[2][3][4][5]
Taxonomy and naming
Eucalyptus lansdownea was first formally described in 1891 by Ferdinand von Mueller and John Ednie Brown in volume 9 of Brown's book, The forest flora of South Australia.[6] The specific epithet (lansdowneana) honours Thomas Lansdowne Browne, who collected the type specimens.
In 1974, Clifford David Boomsma described Eucalyptus lansdownea subsp. albopurpurea in the journal South Australian Naturalist[7] but in 2000, Dean Nicolle raised the subspecies to species level as E. albopurpurea. Eucalyptus albopurpurea has a larger, more robust habit, broader leaves, usually smaller buds and fruit and white, pink or purple flowers.[8]
Distribution and habitat
Crimson mallee is restricted to the south western part of the Gawler Ranges where it grows in mallee vegetation on rocky outcrops and hilltops.[2][3]
