VOLUME XLVIII. THE INTERNATIONAL SCIENTIFIC SERIES. ORIGIN OF CULTIVATED PLANTS. BY ALPHONSE DE CANDOLLE, FOREIGN ASSOCIATE OF THE ACADEMY OF SCIENCES OF THE INSTITUTE OF FRANCE; FOREIGN MEMBER OF THE ROYAL SOCIETIES OF LONDON, EDINBURGH, AND DUBLIN; OF THE ACADEMIES OF ST. PETERSBURG, STOCKHOLM, BERLIN, MUNICH, BRUSSELS, COPENHAGEN, AMSTERDAM, ROME, TURIN, MADRID, BOSTON, ETC. NEW YORK: D. APPLETON AND COMPANY, 1908. AUTHOR’S PREFACE. THE knowledge of the origin of cultivated plants is interesting to agriculturists, to botanists, and even to historians and philosophers concerned with the dawnings of civilization. I went into this question of origin in a chapter in my work on geographical botany; but the book has become scarce, and, moreover, since 1855 important facts have been discovered by travellers, botanists, and archæologists. Instead of publishing a second edition, I have drawn up an entirely new and more extended work, which treats of the origin of almost double the number of species belonging to the tropics and the temperate zones. It includes almost all plants which are cultivated, either on a large scale for economic purposes, or in orchards and kitchen gardens.
