Floyd’s Grass is a spreading stoloniferous perennial that typically forms a dense groundcover (to about 50cm) beneath low-lying swamp sclerophyll forest. The solitary flower heads are small (3-4mm long) and arranged in a panicle. Flowering usually occurs during spring, although it has also been observed at other times of year. The leaves are linear, 1-2mm wide and shiny in appearance.


Floyd's Grass occurs only on the NSW mid north coast from Coffs Harbour to Scotts Head. It is currently known from two disjunct areas: a northern population centred around Sawtell and a southern population along Warrell Creek. Most Floyd's Grass is found on floodplain alluvial deposits between 1m and 2m above the mean tide level, although there are two atypical headland occurences (at Coffs Harbour and Sawtell). 

Habitat and ecology

  • Floyd's Grass occurs predominantly in swamp sclerophyll forest where Swamp Oak Casuarina glauca and/or Broad-leaved Paperbark Melaleuca quinquenervia are usually the dominant canopy species. The plant favours the moderate to high sunlight levels in this habitat.
  • Floyd’s Grass is the sole food plant for the caterpillar of the Endangered Black Grass-dart Butterfly Ocybadistes knightorum.
  • High salinity levels are not tolerated by Floyd's Grass. The majority of its distribution is between 1m and 2m above the mean tide level, i.e. immediatley above the zone of king tide inundation.
  • The most vigorous and extensive examples of Floyd's Grass are found on rich alluvial floodplain terraces. However, the grass will grow on a wide variety of substrates, e.g. it is found on two coastal headlands.
  • The majority of Floyd's Grass is found in riparian zones within 5km of the coast. However, it reaches inland along Warrell Ck as far as Macksville (over 7km from the coast).
