New weed species

Every year, botanists and weed spotters discover and document new alien weed species for Queensland.

Some are declared weeds that are reported to Biosecurity Queensland and some are new weeds that have become established in the state, or have been previously recorded as either cultivated in gardens or doubtfully naturalised (i.e. starting to flower and fruit on their own without the aid of humans) .

All records are verified with a Herbarium ‘voucher specimen’.
