Census arranged in family order
Census arranged in genus order


This Census lists the scientific names of the native and naturalised vascular plants known to occur in the Australian Capital Territory (but excluding the Australian Commonwealth Territory of Jervis Bay on the New South Wales south coast). All records are based on herbarium specimens housed in the Australian National Herbarium (CANB).

As with all censuses, this is a work in progress, and changes to the taxa listed can be expected as new collections and data become available. The census compilers welcome any feedback – please contact us at if you have any comments or corrections.



Family concepts follow those adopted by the Australian National Herbarium. Pteridophyte families follow Brummit (1992) and McCarthy (1998), with some modifications and Gymnosperm families follow Brummitt (1992), with some modifications. Dicotyledon families mostly follow Cronquist (1981), and are generally in keeping with the arrangement adopted by the Flora of Australia . Monocotyledon families mostly follow Dahlgren, Clifford and Yeo (1985), with some modifications.

Genus, species, infraspecies

Taxonomic concepts are those adopted by the Australian National Herbarium. These generally follow those recommended by the Australian Plant Census ( see (where relevant groups have been treated), but may diverge where a differing view is held by research staff at CANB.

Taxa that have not yet been formally published are listed using the format recommended by the Council of Heads of Australasian Herbaria (CHAH) for informal names, as outlined by Barker (2005).

Authors of plant names are not provided for this version of the census. These will be available following linkage of the census to the Australian Plant Name Index (APNI – see in due course.


This field indicates whether a taxon is indigenous to Australia and/or the ACT.

For the purposes of this census, the definition of a naturalised plant is similar to that used by Henderson (2002) for the Queensland flora. It is a plant originating outside of the Australian Capital Territory, subsequently introduced to the ACT by or with the help of human intervention, and persisting there unaided by human intervention.

Naturalised Status

This field is blank for taxa occurring naturally in the ACT.

Non-indigenous plants display varying degrees of persistence and naturalisation in the ACT (and indeed Australia). Some, like Echium plantagineum or Hypochoeris radicata, are common and widespread, with large, widely distributed, self-sustaining populations. Others, like Fumaria capreolata or Cosmos bipinnatus are more ephemeral, with scattered small populations which may or may not persist in the longer term. Taxa in the latter category are treated as Doubtfully Naturalised, indicating that the taxon is known to occur in the ACT and is represented by one or more populations, but the extent of naturalisation is uncertain. These taxa have the potential to become ‘truly’ naturalised.

Similarly, non-indigenous taxa previously recorded from the ACT, but for which no collections have been made within the past 30 years, are treated as Formerly Naturalised.


A representative specimen for each taxon recorded from the ACT, cited by the collector/s name and collection number. In the absence of a collection number (sine numero or s.n.), the CANB/CBG accession number is provided. All vouchers are housed in the collection of the Australian National Herbarium (CANB).

Vouchers were selected on the basis of quality of herbarium material and reliability of the determination. In cases where few specimens were available, the best overall was chosen.


This number corresponds to the taxon’s unique “TAXON_ID” entry in the Australian Plant Name Index (APNI) database ( APNI provides details on the place of publication of the scientific name and includes relevant references from the taxonomic literature.
