English: Boronia megastigma occurrence data downloaded from Australasian Virtual Herbarium 10 April 2019 using doi: https://doi.org/10.26197/5cacda08e37d9 This download included all the environmental overlay fields and ALA's data checking fields including "cultivated / escapee", "outside expert range for species", "latitude is negated", "coordinates are transposed", "taxon misidentified", "habitat incorrect for species", and "suspected outlier" (711 fields). Deleting occurrences for which any of the above were true, 46 specimens with coordinates were deleted. However this did not remove all obvious spatial outliers some of which were later removed by hand. After investigation of spatial outliers using the interactive AVH map, the following specimens were removed (all "suspected outlier"s): CBG 78116242, MEL 1021541A, MEL 0670380A, NE 49529, HO530545, HO551800. These were all specimens found in states other than WA.
