IMPORTANT HARPER TEXTS IN BOTANY

TEXTBOOK OF BOTANYBy TRANSEAU, SAMPSON, and TIFFANY

This thoroughly modern treatment of botany for the year course for beginning collegestudents is one of the outstanding texts in its field, and has been steadily growing inpopularity ever since its publication. It is noted for its emphasis upon environmental andphysiological conditions, its unusual adaptability, and its lavish and beautiful illustrations.Two laboratory manuals which differ materially in approach are available to accompanythe text. $4.50

WORKBOOK IN GENERAL BOTANY, by H. C. SAMPSON. $2.50THE STUDY OF PLANTS, by L. H. TIFFANY. $2.00

The ESSENTIALS OF PLANT BIOLOGYBy FRANK D. KERN

"This new textbook is designed for a one-semester course in elementary botany. The bookemploys a functional approach, yet presents basic botanical concepts in a progressivesequence which enables beginning students to obtain readily a clear understandingof the unity of plant life. . . . Attention throughout is centered upon plant activitiesand interpretation of life phenomena. The broad concepts of plant life bearing on humanculture are expertly merged with the role of plants in contemporary affairs. The book isprofusely illustrated with 260 figures, most of which are new and especially well adaptedto the full development of textual concepts. Several excellent full-page color platescontribute substantially to clarity of detail. . . . Student interest has been attained bygood organization, choice of interesting content, good illustrations, and diversity ofreferences to practical applications of principles. . . . The excellence of content and styleof the book will appeal to students and instructors." W. F. LOEHWING, University ofIowa, in Science, May 4, 1948 $4.00

FOUNDATIONS OF PLANT GEOGRAPHYBy STANLEY A. CAIN

"One of the most stimulating and most thought-provoking works on plant geography andecology the reviewer has read in many years." J. E. POTZGER, Butler University, inThe Journal of the New York Botanical Garden"It is unique in that it represents the first extensive effort toward a general synthesis ofthe results of the two approaches to plant geography: the floristie and vegetational."CARL W. SHARSMITH, University of Minnesota, in Ecology"It is a work that can be studied to advantage by specialists in a wide variety of subjects,ranging from taxonomy to genetics, from paleobotany to polyploidy, and from the natureof species to endemism. It is a work that should be read and digested by all professionalbotanists no matter what their special fields may be, and above all, one that shouldbe intensively studied by all advanced students in botany, again, no matter what theirthesis subject may be. " E. D. MERRILL, in The Scientific Monthly $5.00
