I took quite a few closeups of the flowers and bracts, but I am not sure if there is anything to help distinguish bewteen X. australis and X. glauca - they seem very similar. Nancy Burbidge's book only describes X. australis. These grass trees are in a different location from the others I reported, but I imagine they would all be the same species.

Thanks Jennie, Given that the scape is long, thin and with a slight hook and seems hairless, I'm leaning towards Xanthorrhoea australis - will try and get some one with more knowledge than me to take a look
Cheers Michael

Jennie - Dave Mallison explained that X. australis is not in the ACT plant Census as the CSIRO does not hold any specimens of it - it is a difficult one to collect.

Thanks for sorting out the species. I am glad it was X. australis, otherwise I would have had to add a correction sheet to all the remaining 'World of Tidbinbilla' books as there are numerous references to this species in the book.

The name Xanthorrhoea australis in the ACT is now considered to be a misapplication. That species was dropped from the ACT Plant Census (2017).

The mature packing-bracts of both species exhibit acute to triangular-shaped bracts, however X. glauca possess many non-mature bracts which are spathulate, X. australis flower spikes do not exhibit this phenomena.
