fumida is broadly sympatric with D.
orbata in tropical and
(Map 8) where it grows in a range of
Eucalyptus woodlands on mainly sandy
soils. It is often abundant in the summer season following fire in the previous
mostly November to August.
Notes: This species differs from D. orbata by having a lower glume.
