Natural History

This is the Avocado or Avocado Pear of commerce. This species is occasionally found in the wild on the Atherton Tableland. At first sight it is difficult to envisage any local dispersal agencies. However, dogs (and dingoes) on the Atherton Tableland have developed a taste for the fruit and in some cases they will carry away and bury the seed after consuming the flesh. These buried seeds have been observed to germinate and grow in domestic situations.

The leaves of this species are poisonous Austin, D. F. 1998. Poisonous Plants of Southern Florida. (http://www.fau.edu/divdept/science/envsci/poison- pl.html)

This species has a number of uses. The pericarp is regarded as a tasty delicacy and is a rich source of oil. However, the seeds and leaves are poisonous. (http://squid2.laughingsquid.net/hosts/herbweb.com /herbage/A19613.htm)
