such as A. bivenosa, A. stowardii, S. artemisioides subsp. 
oligochylia x subsp. helmsii, A. pruinocarpa, A. ancistrocarpa 
and S. glutinosa subsp. x luerssenii. These latter species 
occur in other communities, but are typically more 
common here. The species diversity is significantly lower 
here than in most other hummock grassland 
communities and the tree and shrub cover is relatively 
small (Table 3). Floristically and structurally, this 
community is intermediate between 1A/1B and 2A. 
Subtype 3: Hummock grassland and mixed Acacia 
woodland on calcareous, alkaline soils. 
Community 3A: Triodia wiseana - T. longiceps hummock 
grassland with emergent Eucalyptus trivalvis - E. 
socialis mallee (on Oakover and dolomite flats/ 
undulating land; 9 sites). 
This community comprises a mosaic of the two 
hummock grass species (again 20-25% total cover) with
