Fimbristylis subaristata
Fimbristylis subaristata (Data Deficient) is a sparse, annual sedge to 20 cm high – see Figure 21.
There are 21 specimens of Fimbristylis subaristata in Australian herbaria (most in QLD) and three of those in
the NT where it has been collected on sandy gravelly substrates in the western Top End. This species would
be difficult to identify from a specimen taken during the Dry season as much of the fertile material would
have disintegrated. For this reason it is possible that the species is more widespread in the NT than is
indicated by the number of collections.
It was found growing in open woodland on gravelly soil in vegetation type 2 – Corymbia ferruginea +/-
Eucalyptus tetradonta, Eucalyptus phoenicea, Mid Open Woodland.
Likely effect of mining disturbance on species
The effect of mining disturbance on this species is limited with only a small proportion of the total habitat on
the lease (vegetation type 2) being affected by direct impacts.
