General Species Information:
Found in the Flinders Ranges and possibly elsewhere
There are a large number of species in this genus. Not easy to separate. Here it was easy based on the only one in the Flinders Ranges where we took the photo's.
In the Murraylands there are two Yacka (Xanthorrhoea semiplana ssp. semiplana) & Sand-heath Yaccka (Xanthorrhoea caespitosa)
