Corymbia flavescens, commonly known as the Scraggy Cabbage Gum, Wrinkle-leaf Ghost Gum,[1] Cabbage Ghost Gum, Apple Ghost Gum or the Bastard Ghost Gum,[2] is a species of plant in the myrtle family that is native to northern Australia, from the Kimberley region of Western Australia across the Northern Territory to western Queensland.[3]

The Jaru peoples know it as warlarri.[1]

Description[edit]

It grows as a tree up to 15 metres (49 ft) in height, with smooth, white, flaky bark.[3] The bark is powdery and sheds the tree in thin greyish to yellow coloured scales leaving vivid white behind. Adult leaves are concolorous or slightly discolorous, stiff, undulate, glossy and yellow-green in colour. The leaves are predominantly alternate with petioles that are 0.4 to 2 centimetres (0.16 to 0.79 in) long and a ovate to lanceolate shaped blade that is 6 to 23 cm (2.36 to 9.06 in) long and 1.3 to 7 cm (0.51 to 2.76 in) wide with a base tapering to petiole and a pointed apex.[1] It produces cream-white flowers from April to June, or in November.[3] The perfumed inflorescences are compound and axillary and later form a fruit that is pedicellate with pedicels that are 0.2 to 0.7 cm (0.08 to 0.28 in). The fruit is cupular to cylindrical to barrel-shaped with a length of 0.8 to 1.2 cm (0.31 to 0.47 in) and a width of 0.8 to 1.1 cm (0.31 to 0.43 in). Seeds are a dull to semi-glossy red or red-brown colour with a regular and flattened, patelliform and ovoid shape that is shallowly reticulate.[4]

C. flavescens has a lignotuber and will form an epicormic shoot in response to fire. As a result, the tree has a lower than 30% mortality rate even if all of its leaves are scorched during a bushfire.[5]

Distribution and habitat[edit]

It occurs on red earth soils, often along watercourses. In Western Australia it is found in the Central Kimberley, Dampierland, Great Sandy Desert, Northern Kimberley, Ord Victoria Plain, Pilbara, Tanami and Victoria Bonaparte IBRA bioregions.[3] In the Northern Territory it is found in the Davenport Murchison Ranges, Gulf Fall and Uplands, Mitchell Grass Downs, Mount Isa Inlier and Sturt Plateau IBRA bioregions.[1]
