THE WESTERN FLOWER GUIDE

By CHARLES FRANCIS SAUNDERS

This little volume, uniform with the Pocket Nature Guides, is a comprehensive and compact treatment of the flower life between the Mississippi and the Pacific coast. Its coloured illustrations and the accompanying text make it easy to identify any specimen.

Flowers are described in family groups, and are thus, by a study of resemblances and contrasts, made easier to master. The colour work is attractive and accurate, being reproduced from the work of well known flower portrait painters. The book is prepared by authorities, and the needs of the general public have been considered in the manner of presentation. A bibliography is provided for readers who wish to undertake a more detailed study. Of convenient pocket size, it is an ideal handbook of flower information.
