<eolonies, and is a cosmopolitan grass in addition. In New South 

 Wales it is found in most parts of the Colony. The following note ' 

 from a correspondent from Myall Plains, near Jerilderie, explains one 

 of its habitats : 



" Only growing on some land that was cleared and burnt off last 

 -January, and only in the stump holes and ashes where the trees were 

 Tfournt, and as thick as it can grow. It is quite unusual for grass to 

 -grow here for several years where large trees or heaps of wood or 

 scrub are burnt, but this grass seems to come up at once, and do well 

 where the most ashes are found. It grows so high and rank that you 

 can trace where every portion of the tree has been burnt."
