Notes. The collections designated as Grevillea brachystylis subsp. australis can be distinguished 
from G. brachystylis subsp. brachystylis by the purple pollen presenter, the branches being up to 2 
m long (instead of 40-70 cm), often erect, and much branched. No intermediate populations are 
known because of the disjunct nature of the species. 
Etymology. From the Latin australis, referring to the southern distribution of this subspecies. 
Habitat. Both varieties occur on winter wet fiats normally covered by heath with sand over day.
