The second case was outside the Western Australian Herbarium, where a plant was growing from commercially obtained 'native plant seed'.

Most disturbingly, the government response was reported as being that this weed was unlikely to be a problem and that there were insufficient resources to react to 'anything other than the most dire  of biosecurity threats'.

The combination of reduced taxonomic skills and inadequate resourcing can lead to weeds being allowed to establish.
