Johnson's Grass Tree (bushfire recovery)
Xanthorrhoea johnsonii
-28.8698, 151.969
Field Notes
Description:
Not the echidna I first thought it was, but rather, I had spotted a grass tree, and it was reshooting after recent bushfires burnt through this region in 2019. There are two species documented in Girraween.... Xanthorrhoea johnsonii, commonly known as "forest grass tree" or "Johnson's grass tree", and Xanthorrhoea latifolia ssp. latifolia, of which I'm unable to find a common name other than the generic "grass tree". These species belong to the family Asphodelaceae, and the Xanthorrhoea genus contains roughly 30 species, of which these two are endemic to eastern Australia. Grass trees have a very slow growth rate and can live for hundreds of years, so this specimen is still very young, although it has all the character which is so typical of the grass tree species. NB: I have selected X. johnsonii as the spotting ID for the simple reason that it has been mentioned by three independent local sources in reference to this national park. PS: This is a spotting I made in Brisbane last year, and it shows X. johnsonii in flower.... https://www.projectnoah.org/spottings/785324295 It is such an unusual plant.
Habitat:
Spotted along the Peak Trail in Girraween National Park. Grass trees occur mainly in soils that are very free-draining and consequently low in nutrients - sandy granite soils in this case. Area largely dry sclerophyll forest, and foliage is much greener and lush since the drought has broken. Exposed to full-sun along this section of track, and there were some areas that were still damp and muddy from recent rain. Here's some park info - http://www.rymich.com/girraween/ https://en.wikipedia.org/wiki/Girraween_National_Park
Notes:
Both species of Xanthorrhoea are a source of "bush tucker". Honey Production: honey source minor, pollen source minor. Dry flower stalks used for fire-making. Bush food: edible nectar, seeds and leaf bases. Grubs in trunk base. (Noosa's Native Plants)
