It’s not a botanical term.  It is an ecological term used to describe the 
broken remains of Allocasuarina seed cones lying under the tree after being 
broken by birds (usually Glossy Black-Cockatoos) in the process of extracting 
the seeds.  The number of orts under a tree is used as a measure of the level 
of food/feeding activity at the tree and the colour of the orts provides a 
guide to the length of time that has elapsed since they were broken.
