Original author
Dr Francis Rose, MBE
Dr Rose is one of our best-known botanists, with an encyclopaedic knowledge of the lichen and bryophyte flora as well as of flowering plants, and of plant ecology and biogeography. His career as a botanist began at the age of six, learning to identify plants on country walks and after graduating in botany from London University, he spent most of his working life teaching there until retirement in 1981. This remains his most popular book, which took over 20 years to write and represents a lifetime's experience of plant identification.

Author of revised and expanded second edition
Clare O'Reilly
Clare O'Reilly (previously Coleman) is a freelance botanist and writer who left her career as an environmental lawyer in order to revise this book. She recently gained an MSc in Plant Taxonomy but was a self-taught amateur botanist for many years. Her passion for plants began after winning a wild flower-in-a-vase competition, aged seven. Clare teaches beginners courses on plant identification and this experience, coupled with Dr Rose's expertise in the original text, enables this revised edition to be even more useful for those new to field botany.
