This edition is updated to align with current systems of plant classification that incorporate advances in molecular DNA analysis. It includes more than 130 detailed line drawings, 64 colour pages and information on 46 plant families. The illustrations depict a selection of widely distributed gardens plants and weeds, and species native in eastern and southeastern Australia. Easily navigated, the book facilitates the successful use of standard identification manuals and online resources available in most parts of the world and introduces the reader to the arrangement of flowers on plants, reproduction, plant structure and function, and the way species are grouped and named. Methods for dissecting flowers and observing their structure for identification purposes are clearly described.
