This digital reprint of the 1963 original is a companion volume to the text by A. R. Clapham, T. G. Tutin and E. F. Warbur. The drawings are by Sybil J. Roles. These volumes illustrate the Clapham-Tutin-Warburg Flora of the British Isles. The drawings assist users of the Flora to recognise species by supplying a visual supplement to the text. They are from fresh specimens and deliberately aim to give an impression of the living plant. As the compilers of the Flora put it, 'The intention is to provide a visual impression so as to assist with the appreciation of the technical descriptions given in Flora of the British Isles and the Excursion Flora'. The degree to which the illustrations planned to supplement the Flora itself greatly increases their value; the books are meant to be used together.
