Eucalyptus incrassata

Eucalyptus incrassata, the ridge-fruited mallee or lerp mallee, is a small mallee eucalypt in the family Myrtaceae endemic to semi-arid southern Australia, where it dominates extensive areas of mallee woodland on sandy and sandy-loam soils. It typically grows 2-7 m tall, forming a multi-stemmed lignotuberous shrub or small tree with smooth, shedding grey to coppery bark over reddish new bark. Adult leaves are lanceolate, glossy green on both surfaces, and pendulous. The cream to pale yellow flowers are borne in seven- to eleven-flowered axillary umbels and are followed by characteristic conical to barrel-shaped fruits with prominent longitudinal ridges and a deeply enclosed disc, giving the species its name. It tolerates drought, fire, and nutrient-poor soils and resprouts vigorously from its lignotuber after disturbance.
