Flora census

The 2018 Census of the Queensland Flora provides a published list of all the known native and naturalised species of plants, algae, fungi and lichens in the state.

Our flora now has 14,385 known native species across all groups. That’s nearly double the number listed in 1913 (7,781 species). More than 20 species new to science are discovered in Queensland each year.

Separate listings of the naturalised and doubtfully-naturalised flora are also presented for the use of weed officers. Species only present in cultivation are not included in any of the census lists.

The current list is generated from the Queensland Herbarium specimen label information database as of 1 August 2018. These records are primarily based on the Queensland Herbarium specimen collections representing 240 years of verified specimen data.

The taxonomy of a number of plant families is evolving. This particularly applies in Orchidaceae at the generic level. Queensland Herbarium staff are working towards a consensus regarding the application of scientific names to orchids where the views of researchers vary.

2018 data

This census data are available through the Open Data website and presented in spreadsheets for:

  • vascular plants—flowering plants, conifers, cycads, ferns and fern allies, including native and naturalised species
  • non-vascular plants—mosses, liverworts, hornworts
  • algae—green and red algae, brown algae and diatoms (Chromista)
  • bacteria—Cyanobacteria only, formerly called blue-green algae
  • fungi—including macrofungi and lichens
  • current and former naturalised species, and doubtfully-naturalised species
  • vascular plants—hyperlinked to JSTOR images of Type specimens where available
  • Endangered, Vulnerable, Near Threatened and Presumed Extinct plants.

More information on the classification of these groups is available in the census introduction (PDF, 707KB).
