The six landscape images in Alien Invaders appear as documents of selected South African locations representative of different floral biomes. The images were selected on the basis that, although they were photographed through a regular lens and from a standard viewpoint, they demonstrate no obvious signifiers which promote 'meaning' or 'message', and the photographs themselves are neither cropped nor manipulated. Each landscape is host to a particular printed shape and colour representative of a plant invader species.
The invaders thus represented are:
1. The water hyacinth (Eichhornia crassipes).
2. The red sunflower (Tithonia rotundifolia).
3. Sisal (Agave sisalana).
4. Morning glory (Ipomoea indica and Ipomoea purpurea).
5. The moth catcher (Araujia sericifera).
6. Prickly pear (Opuntia ficus-indica).
The manipulated photographs are affixed with corner guards in landscape format with the binding at the top of the image. Bound in black leather and signed on the back endpaper.
