Marri

Corymbia calophylla

Appearance

  • Tree with tessellated bark.
  • Size: 40 – 60 m high.
  • Leaves: lance to oval shape.  Veins are distinct.
  • Flowers: White to pink.
  • Fruit/seed: Urn shaped fruit 0.7 – 1.4 cm long, 0.7–1 cm diameter.  

What to Observe

  • First fully open single flower
  • Full flowering (record all days)
  • End of flowering (when 95% of the flowers have faded)
  • No flowering

ClimateWatch Science Advisor

We expect plants to start shooting and flowering earlier in the year as a result of climate change warming the Earth. They may also start appearing in new areas, as warmer temperatures enable them to live in environments that were previously too cold for them.

When To Look

  • Tree is present all year.
  • Flowers from December to May.

Where To Look

  • South Western Australia
  • Ranging from Geraldton to Albany.  Inland to Albany highway.
  • Widely spread

Above, the left and middle maps show the modelled habitat suitability for the the species under current and potential future climate conditions. The colours indicate the predicted habitat suitability from low (white) to high (dark red).

The future habitat suitability is modelled for the year 2070 under a climate change scenario that represents 'business as usual' (RCP 8.5). The map on the right shows how the range of the species might change between now and 2070, with orange areas indicating where the species might disappear, green areas where the species range might expand, and blue areas where the habitat is predicted to be suitable for the species now and in the future.

The models for this species were run in the Biodiversity and Climate Change Virtual Laboratory. Please note that while models can be very informative, they are only a representation of the real world and thus should always be viewed with caution. You can read more about the science behind these models here.

  1. What Else?

    Marri is superficially similar to Corymbia ficifolia. However 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. C. ficifolia always has scarlet flowers, while marri flowers are almost always white

  1. Did You Know?

    Corymbia comes from Latin, corymbium, a "corymb" refers to floral clusters where all flowers branch from the stem at different levels but ultimately terminate at about the same level.

    calophylla comes from Greek calo, beautiful, and phyllon, a leaf.
