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.

Apple iOS iOS - Apple iTunes

Android Android - Google Play Store

Rainforest Plants of Australia – Rockhampton to Victoria, is based on the popular interactive computer key (distributed as a USB) of the same name. The app includes the full identification key to 1140 species, fact sheets for all species and features used in the key, introductory and reference sections and over 8,000 images.

Rainforest Plants of Australia has been developed to identify trees, shrubs and climbing plants that occur naturally or have become naturalized (including exotic weeds) in rainforest from Rockhampton to Victoria. It is a fantastic resource, a thorough and comprehensive source of information for all those concerned about rainforests, their biodiversity, distribution and conservation. The app will be vital for researchers and teachers at universities, TAFEs and schools, environmental consultants and government agencies, community groups and landowners, bushwalkers, gardeners and anyone with an interest in rainforests or rainforest plants.

Both plain English and botanical terms (explained in an illustrated glossary) are used throughout the app to make it applicable to as wide an audience as possible. Despite its Australian focus, this key provides a resource for users in other countries. It shows what type of information is useful and what features can be used in separating rainforest species. It demonstrates how powerful the Lucid Mobile platform is and that such an app can be prepared using this program. At the core of this app is an interactive identification key powered by Lucid.

The key includes 1140 plant species that grow in rainforest of eastern Australia, from Rockhampton to Victoria. To help confirm identification the app provides line drawings, over 8,000 photos and extensive information on each species, including previously unavailable botanical details.

A customised image gallery walk-through tutorial assists the user in working the key and accessing the content. The introductory sections include information and images on rainforest and the types of rainforest used in this app. Hints are provided on how to identify rainforest plants as well as an outline of the special features and terms used to separate the many species that on first sight appear to be inseparable!

Due to app size constraints, the 12,000 images in the USB version of Rainforest Plants of Australia – Rockhampton to Victoria have been reduced to around 8,000 images, retaining the most useful for identifying plants in the rainforest.
