Location Narrative	This is a herbaceous stand on thin rocky soil. It is dominated by Calycadenia truncata and Lessingia virgata, which are still in bloom. The rock outcrops are covered with Selaginella hansenii. The gravelly flats contain Vulpia, Plantago, and Clarkia. The survey was conducted late in the season. The stand is adjacent to an area under powerlines that may have been cleared.
