The '''Sugar Gum''' (''Eucalyptus cladocalyx'') is a [[Eucalyptus|eucalypt]] from [[South Australia]]. It is found naturally in three distinct populations - in the [[Flinders Ranges]], [[Eyre Peninsula]] and on [[Kangaroo Island]]. Sugar Gums from the Flinders Ranges reach up to 35m in height and have the classic "gum" habit - with a straight trunk and steep branches occurring about half way up. Each main branch ends with its own little canopy. These are commonly cultivated as farm [[windbreak]]s and for timber. However, Eyre Peninsula and Kangaroo Island trees are much shorter and often have crooked trunks.
''E. cladocalyx'' has no close known relatives within the ''[[Eucalyptus]]'' [[genus]]. It is notable for its mottled colourful yellow to orange bark, strongly discolourous leaves and inflorescences grouped on leafless branchlets inside the [[tree crown]].
The old [[bark]] is smooth and grey, shedding in irregular patches to expose the fresh yellowy-brown bark. Flowers are creamy-white in summer. The capsules are barrel to urn shaped.
