The above is a very distinct geographical variety and has 

 very little in common with the typical form. Although 

 approached by some examples of var. dnnwrilii, it is neverthe- 

 less constantly separated by the characters given above. It is 

 worthy of note however, that the specimens of var. ilinuerUli 

 which show the closest affinity to this form, occur on the Great 

 Dividing Range in a region where the range may be said to be 

 the eastern boundary of the Riverina District, and the habitat 

 of var. iHterioris:.
