Ok, so here are some Xanthorrhoea, or grass trees.    From Wordnik.com.  [Archive 2008-03-01] Reference

Now largely cleared, marri (Eucalyptus calophylla) – kingia (Kingia australis) woodlands grow on heavy soils of the Swan Coastal Plain, and marri – grass tree (Xanthorrhoea preissii) woodlands and shrublands also grow on the Swan Coastal Plain.    From Wordnik.com.  [Swan Coastal Plain scrub and woodlands] Reference

The relict alluvial dune fields east of the Warrego River in Queensland support a diverse "heath" flora and several species at the western edge of their distribution such as Eucalyptus melanophloia, E. ammophila, Casuarina inophloia, and Xanthorrhoea johnsonnii.    From Wordnik.com.  [Eastern Australia mulga shrublands] Reference

Root disease is now spreading to other habitats, including kwongan shrublands, and in particular Stirling Range National Park, where it has caused mortality among susceptible plants like the peculiar grass trees (Xanthorrhoea spp.) and members of the Proteaceae, especially the banksias (Banksia spp.).    From Wordnik.com.  [Biological diversity in Southwest Australia] Reference

Further up you see a lot of Xanthorrhoea, or Grass Trees.    From Wordnik.com.  [TravelPod.com Recent Updates] Reference

Some more Xanthorrhoea were seen, and several small creeks joined this from the ranges to the north.    From Wordnik.com.  [Australia Twice Traversed, Illustrated,] Reference

Xanthorrhoea, reaching a height of twelve feet, was seen on the ranges along Rudall's Creek, but no specimen for examination was secured.    From Wordnik.com.  [Australia Twice Traversed, Illustrated,] Reference

This valley is remarkable as containing one Xanthorrhoea (grass-tree) being the farthest point to the north at which I have found this tree.    From Wordnik.com.  [Journals of Two Expeditions of Discovery in North-West and Western Australia, Volume 2] Reference

A number of grass-trees (Xanthorrhoea) grew near the spot where we had halted; they appeared unhealthy and stunted, but indeed I suspect they are a new and undescribed variety.    From Wordnik.com.  [Journals of Two Expeditions of Discovery in North-West and Western Australia, Volume 2] Reference

The country was sandy, and bedecked with triodia, but near the range I saw for the first time on this expedition a quantity of the Australian grass-tree (Xanthorrhoea) dotting the landscape.    From Wordnik.com.  [Australia Twice Traversed, Illustrated,] Reference

Grubs are principally procured by the natives from the Xanthorrhoea or grass-tree, but they are also found in wattle-trees, and in dead timber; those found in the grass-tree have a fragrant aromatic flavour and taste very like a nice nut.    From Wordnik.com.  [Journals of Two Expeditions of Discovery in North-West and Western Australia, Volume 2] Reference

But we had left, as it seemed, all the good grassy land behind us; for the stringybark and a species of Xanthorrhoea (grass-tree) grew to the water's edge both where the soil looked black and rich and where it possessed that red colour which distinguishes the best soil in the vicinity of limestone rock.    From Wordnik.com.  [Three Expeditions into the Interior of Eastern Australia, Volume 2] Reference

Winterrowd described their new book as "50 chapters about various plants that have been special to our long gardening life, such as cyclamen, agapanthus, tender rhododendrons, etc., and some rarer ones such as Xanthorrhoea quadrangulata, a single huge potted specimen of which we have owned for thirty years.".    From Wordnik.com. Reference

A number of Swan Coastal Plain woodland communities are listed as Endangered under the Commonwealth Environment Protection and Biodiversity Conservation Act: marri (Eucalyptus calophylla) – kingia (Kingia australis) woodlands on heavy soils, marri (Eucalyptus calophylla) – grass tree (Xanthorrhoea preissii) woodlands, and shrublands, shrublands, and woodlands of the eastern Swan Coastal Plain, shrublands and woodlands on Muchea Limestone of the Swan Coastal Plain, and shrublands and woodlands on Perth to Gingin ironstone.    From Wordnik.com.  [Swan Coastal Plain scrub and woodlands] Reference

Understories are often dense and diverse, composed of large Xanthorrhoea tussocks and small-leaved sclerophyllous shrubs (e.g.    From Wordnik.com.  [Murray-Darling woodlands and mallee] Reference

The forest and woodland understories tend to have a species composition similar to the heath regions, being made up of Xanthorrhoea tussocks and small-leaved sclerophyllous shrubs (e.g.    From Wordnik.com.  [Naracoorte woodlands] Reference

The same rule holds good with regard to animal productions; for example in the southern parts of the continent the Xanthorrhoea affords an inexhaustible supply of fragrant grubs, which an epicure would delight in when once he has so far conquered his prejudices as to taste them; whilst in proceeding to the northward these trees decline in health and growth, until about the parallel of Gantheaume Bay they totally disappear, and even a native finds himself cut off from his ordinary supplies of insects; the same circumstances taking place with regard to the roots and other kinds of food at the same time, the traveller necessarily finds himself reduced to cruel extremities.    From Wordnik.com.  [Journals of Two Expeditions of Discovery in North-West and Western Australia, Volume 2] Reference

On Saturday, the 25th of September, being the sixteenth day from the water at the Boundary Dam, we travelled twenty-seven miles, still on our course, through mallee and spinifex, pines, casuarinas, and quandong-trees, and noticed for the first time upon this expedition some very fine specimens of the Australian grass-tree, Xanthorrhoea; the giant mallee were also numerous.    From Wordnik.com.  [Australia Twice Traversed, Illustrated,] Reference
