A description in detail of 107 major indigenous trees; the first survey published since the Forest Flora of South Australia (1883-1890).

In the introduction the technique of plant description is explained. Also honey and pollen yield is listed. Each species is depicted on a plate with a map of distribution in the State. And the caption to each plate provides detail information of field data. A well-executed, useful work.
