Commonwealth status: Endangered
Profile last updated: 24 Jul 2019

Description

An erect perennial grass to 0.9 m high. Leaves are 2 - 4 mm wide, deeply grooved, with a rough lower surface and a hairy upper surface. The leaves have a 1 - 2 mm long ligule (appendage towards the base of leaf) that is membranous, truncate and jagged. The moderately dense panicle (compound inflorescence) is 20 - 30 cm long, possessing spikelets that are about 3.5 mm long. Glumes (two bracts at the base of spikelets) are slightly unequal, 1-nerved, keeled, and very acute.

Distribution

A highly restricted NSW endemic known only from two pre-1942 records in the Sydney area. Was first collected in 1930 at Herne Bay, Saltpan Creek, off the Georges River, south of Bankstown. Was then collected in 1941 from Killara, near Hornsby. Has not been collected since and may now be extinct in the wild due to the level of habitat loss and development that has occurred within these areas.

Habitat and ecology

  • Given that D. appressa hasn’t been seen in over 60 years, almost nothing is known of the species' habitat and ecology.
  • Flowers spring to summer and is mesophytic (grows in moist conditions).
