Corymbia calophylla (also known as Eucalyptus calophylla R. Br.) is a bloodwood native to Western Australia. Common names include Marri and Port Gregory Gum,[1] and a long-standing usage has been Red Gum due to the red gum effusions often found on trunks.

It is distinctive among bloodwoods for its very large buds and fruit (colloquially “honky nuts” in Western Australia).
In 2009, Parra-O and colleagues published a combined analysis of nuclear rDNA (ETS + ITS) and morphological characters published to clarify relationships within the genus Corymbia. C. calophylla was found to form a natural group with two other Western Australian species C. ficifolia and C. haematoxylon. They classified the group as section Calophyllae within the subgenus Corymbia.[2]

It is related and somewhat similar to the Red-flowering Gum (Corymbia ficifolia). C. 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. However, in some areas hybridisation makes identification difficult.
It will grow on comparatively poor soil, but good specimens are considered an indicator of the better agricultural soils.

It is my pleasure to share few images of Corymbia calophylla,formerly Eucalyptus calophylla (Myrtaceae)

Commonly known as the Red Gum, Marri, Port Gregory Gum etc. this species is distinct from the similar looking Corymbia ficifolia that has red flowers instead of white to pink as in the instant specimen. 

Habit: A large tree over 50 m height. 

Habitat: Planted long ago, Possibly around or after the reign of the then Ruler of Mysore, Tippu Sultan who introduced Eucalypts in India around 1790…! 

Sighting: Chikmagalur, Karnataka, about 1000 msl
