Preface

I take over the task of continuing the work of my friend, the late Mr. H. Rackham, with many fears lest my effort prove an unworthy sequel.

A complete index of plants will be found at the end of Volume VII. To identify each plant or tree as it occurs would have involved many repetitions and cross-references, but a few identifications have been inserted in the text and notes where they seemed specially needed.
