Eucalyptus gracilis, commonly known as kong mallee, yorrell, or snap and rattle, is a tree native to Australia, where it is found from southwestern New South Wales, Victoria, South Australia, and Western Australia.
The open to spreading, multi-stemmed tree typically grows to a height of 20 metres (70 ft) with rough brown bark at the base that becomes smooth and a coppery-creamy in colour above. It blooms between March and October producing creamy-white flowers. The adult leaves are disjunct, glossy, green, concolourous and have a narrow-lanceolate shape. They are 5 to 8 centimetres (2.0 to 3.1 in) in length and 0.8 to 1.5 cm (0.31 to 0.59 in) wide. The inflorescences have seven-flowered umbellasters and a quadrangular peduncle that is 5 to 10 mm (0.20 to 0.39 in) long on terete pedicels. The buds are clavate and approximately 4 to 6 mm (0.16 to 0.24 in) long with a diameter of 3 to 4 mm (0.12 to 0.16 in) diameter.
The species was first formally described by the botanist Ferdinand von Mueller in 1854 as part of the work Second systematic index of the plants of Victoria. in Victoria – Parliamentary Papers – Votes and Proceedings of the Legislative Assembly. The species name is the Latin adjective gracilis "slender", likely referring to its branches and habit.
Common names include snap and rattle, red mallee, white mallee, yorrell, and kong mallee.
Eucalyptus yilgarnensis was formerly considered a subspecies of this species.
It grows on sand dunes and plains, crests of rises and along creek lines in the south eastern Wheatbelt and Goldfields-Esperance regions of Western Australia where it grows in sandy-clay-loamy soils over limestone. It is found throughout most of southern and central South Australia and into Victoria and south western New South Wales where it is found in mallee shrubland on red aeolian sands south from Yathong and west from West Wyalong.
