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’.

These species have not previously been recorded as naturalised in Queensland.

The new naturalisations for the year July 2015 to June 2016 are listed in the Weed Spotters Network Queensland Bulletin October 2016.
