Corymbia calophylla – Xanthorrhoea preissii woodlands and shrublands of the Swan Coastal Plain..  In 2009, Parra-O and colleagues added more taxa and published a combined analysis of nuclear rDNA (ETS + ITS) and morphological characters published to clarify relationships within the genus. calophylla differs in being much larger (to about 50 metres (160 ft) high in the wild), having very much larger buds and fruit, and having flowers that are usually white to pink instead of red. The trunk responds to damage by insects by exuding a red, blood-like substance, a type of kino, that is able to be collected for a variety of uses. Each branch of the peduncle has buds in groups of three or seven on pedicels 6–37 mm (0.24–1.46 in) long. Synonyms. Corymbia calophylla. Removal of trees at farmland was found to be difficult, resisting labour-intensive mechanical methods and ringbarking, the cost-effective method, demonstrated in 1904 at an experimental farm in Narrogin, was to splinter the trunks and roots with Gelignite. In the flowering season in summer the buds burst into clusters of fluffy cream flowers which are held outside the canopy making a wonderful display.  All three genera, Angophora, Corymbia and Eucalyptus, are closely related, and are generally referred to as "eucalypts".

It differs in that it has urn-shaped fruit rather than barrel shaped, its seeds are larger and do not have wings, and its oil glands in the leaves are prominent. Red gum was recorded as a name in use by the Swan River colonists in 1835. Formerly known as Eucalyptus calophylla, Corymbia calophylla is a large tree that can grow up to 40 metres in height and occurs naturally through the south-west of Western Australia in a range of habitats. , Old large trees became rare after extensive agricultural conversion of land during the twentieth century, but Mueller recorded specimens in the 1870s with trunks up to three metres in width. Characteristics of Marri (Corymbia calophylla) fruits in relation to the foraging behaviour of the Forest Red-tailed Black Cockatoo (Calyptorhynchus banksii naso) Christine Cooper , Philip Withers , P.R. , Mueller placed the species with a series of 'bloodwoods' in 1884, based on characteristics of the bark.

C.henryi is restricted to an area between about Brisbane and Coffs Harbour. Key results Marri (Corymbia calophylla) and jarrah were commonly consumed in unmined forest and Banksia and Hakea species were also fed on to a lesser extent.

He did not give a reason for the specific epithet (calophylla), however Ferdinand von Mueller noted in 1879 that Brown "bestowed the specific name on this tree seemingly for a double reason, because the foliage is more beautiful than that of many other Eucalypts, and also because the venation of the leaves reminds of that of the tropical genus Calophyllum in the plants-order of Guttiferae. , The marri range and population has increased and decreased with recent environmental changes, urban development, land clearing, intensive agriculture and altered fire regimes.  Mueller noted in Eucalyptographia (1879) that the tree could be grown in tropical climes, giving John Kirk's report of its successful introduction to Zanzibar, but that its sensitivity to frost had accounted for its failure in Melbourne, Australia and other regions. Corymbia calophylla is one of around 80 eucalypts which were transferred in 1995 from the genus Eucalyptus to the newly created genus Corymbia. the eucalypt Marri (Corymbia calophylla) and often only from specific feed trees. The value of marri lacking gum veins was propounded by the state conservator of forest John Ednie Brown in 1897, with a recommendation they be used for packaging fruit, however, the 1922 commission found that while useful for that purpose and others, the irregular faults reduced its utility.
