Key SearchWelcome to the Lucidcentral Key Search

There are two ways you can search for a key in the Lucid key database. First, you can type in a word or words in the “Search” box to the right of the screen and press Go. This search will display all those keys that have the word(s) you entered in the title of the key. The alternative way is to use one or a number of the search categories below, using the drop down menus. So, for instance, you could search for an internet key (under Media/Deployment), of Higher plants (Taxonomic scope), terrestrial (Habitat) and Australia (Geo Scope).

We recommend that you check whether you have the latest (free) version of Java Runtime Environment and if necessary upgrade to the latest version when running keys based on the Lucid Player applet.


Key to willow species and hybrids present in New Zealand  --  VISIT
 Views: 38

Updated: Mon 05/27/2019 @ 04:04

This key is illustrated with more than 2000 images of willow species and hybrids that are either wild or in cultivation in New Zealand, and the features that are used to identify them. Most illustrations are of willow clones grown in the national willow collection in Palmerston North maintained by Plant and Food NZ.

The key is designed for those with some experience in plant identification, and some features will need at least a strong hand lens (10x or better) to see features such as stamen filament hairs. It will be of use to bee-keepers, farmers with an interest in growing willows as bee food, and conservation estate managers who need to identify willows in the wild.

Writing of this key was funded by the Sustainable Farming Fund, Trees for Bees NZ, the Willow and Poplar Trust, Plant and Food NZ, and Manaaki Whenua - Landcare Research.

Plants of South Eastern New South Wales  --  VISIT

Plants of South Eastern New South Wales 


This key is designed for anyone who has an interest in finding out about the plants of south eastern New South Wales. It includes about 2,900 species of plants accompanied by about 10,000 images. It includes Eucalypts, but not ferns, orchids, grasses, or most sedges or rushes. There are about 3,900 relevant species in the area covered by this key.

The key mostly uses easily seen characters and a minimum of technical terms to help with the identification of plants. It is not designed to key out to a single species, though sometimes it does. It is designed to narrow down the possibilities of what the plant might be to a limited number of species. The photos may then help you decide what your plant is.

In most cases, the use of a hand lens or a low power microscope is not necessary for identification, except when counting the number of flowers/florets in a flower head, and deciding whether hairs on stems are stellate (multiple hairs arising from a point, looking like a star), branched, or simple. Identification needing the use of a high power microscope is beyond the scope of the key.

Spider mite species of Australia (including key exotic southeast Asian pest species)  --  VISIT
 Views: 121

About the key

This interactive key provides diagnostics for all the species of spider mites (Acari: Tetranychidae) previously recorded in Australia, based mostly on literature records. Several species collected in Australia, but not yet recorded in the literature, are also included (manuscript in prep). In addition, a few select exotic species from south east Asia of concern to Australia’s biosecurity have also been included, and are indicated by ^^ after the species name. Where possible, the diagnostics (images and data) presented in this key were taken from direct examination of the type specimens. A detailed fact sheet has been provided for nearly all species treated. Australian voucher specimens have not been examined for all species treated in this key, and some records are in need of further investigation.

Note well: voucher specimens were not examined for all species treated in this key, and that several groups of species cannot be separated, but this may change with updates. For example, all the Bryobia species listed cannot be separated from each other, and the members of the Oligonychus ununguis species group are notoriously difficult to separate. When this occurs, unfortunately, the key will continue to present you with character state options, even though no further resolution is possible. In these cases, you must rely on examining the fact sheets for each of the remaining taxa. In addition, there are a few species with various taxonomic issues, for example Tetranychus lambi, where there are possibly two species represented in the type series, and as such, separating that taxon cleanly is not possible as certain character features have multiple character states present.

Note also: that the key opens with female characters only. As characters are selected, the relevant male characters will open for the user to see.

Please contact the author ( if you have any issues with the key not working, or suggestions for improvement etc.


Development of this key has been funded under the Australian Government’s Agricultural Competitiveness and Developing Northern Australia white papers, the government’s plans for stronger farmers, a stronger economy and a safe, secure Australia.

Thrips of the British Isles  --  VISIT

Thysanoptera Britannica et Hibernica

Thrips of the British Isles

This identification and information system includes 177 species of thrips that have been taken alive on the British Isles at least once. It provides a means of identifying species, together with an introduction to what is known of the biology and distribution of each species. The identification system is based largely on adult females as this is the life stage most commonly collected. Printed identification keys that similarly deal with adults of the British thrips fauna include Mound et al, (1976) and zur Strassen (2003), and for larvae an extensive introduction is provided by Vierbergen et al. (2010).

Wattle Acacias of Australia v3  --  VISIT
 Views: 497

Updated: Fri 08/31/2018 @ 06:42

This WATTLE ver. 3 key (which is also available as an App) enables users to identify wattle plants that occur anywhere in Australia or elsewhere in the world where they are grown. It includes 1,057 formally described species of Acacia, plus several hybrids and informal taxa of this genus. It also includes two species of Acaciella, four species of Senegalia and nine species of Vachellia that occur in Australia and which were previously included in Acacia.

WATTLE ver. 3 builds upon two previous versions of WATTLE, namely, the original version that was published in 2001 on CD and version 2 that was published in 2014 on the Lucidcentral website. Compared with earlier versions, which are no longer available, WATTLE ver. 3 contains more species, updated coding and new or updated descriptions for each taxon, together with photographs and improved distribution maps.

At the heart of WATTLE is a powerful Lucid identification key which helps people of all ages to quickly and accurately identify species. The key is a truly random access tool, one that allows users to enter, in any order, the characteristics of a specimen that they wish to identify. The key then lists those species possessing the characteristics nominated, rejecting those that do not match the criteria entered. By progressively providing additional characteristics about the unknown specimen, users can narrow the search, eventually ending up with just one or a few species.

The key provides context-relevant information (text and images) that assist users to correctly interpret the characteristics of the plant they are attempting to identify. For those who want information about the species that has been identified, WATTLE ver. 3 provides fact sheets containing illustrations, detailed descriptions, photographs and maps that can be accessed directly. Hyperlinks provide simple navigation between fact sheets of related or similar species.

WATTLE ver. 3 is jointly published by the Australian Biological Resources Study (ABRS), Canberra, The Western Australian Department of Biodiversity, Conservation and Attractions (formerly CALM) and Identic Pty Ltd, Queensland. WATTLE complements the Flora of Australia (
