This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1896 Excerpt: ... species very common East and West, such as Yellow-eyed grass (Hypoxis Erecta), Spiderwort (Tradescantia Virginica) and Spice Bush (Lindera Benzoin) but probably no two botanists would agree upon the same list of 150 flowers commonest East and West. The pupil has, moreover, or should have, access always to Gray's Manual or Wood's Class Book if this smaller manual fails him. It is undoubtedly true that the old method of analysis and identification of a large number of species has been overdone, and that the better method is that of comparative study of the more important families as indicated by Spalding. Yet Mr. Bergen's book contains enough material to give the student the method of floral analysis which every student of botany should understand. This book contains more distinct features than any elementary text book with which I am acquainted. Running through it without attempt at sharp divisions are directions for laboratory work of a morphological and physiological sort as well as directions for the study of gross and minute anatomy. This latter feature calls for the use of the compound microscope in the hands of each student or each small group. The physiological experiments are 33 in number. The author follows the plan of Gray's Elements both in dwelling very largely on phanerogamous plants and in his order of presentation of topics. He follows the cycle of development from seed and root through stem, bud, leaf, flower, and fruit back to seed again. The physiology and morphology of these organs are carefully presented. The minute anatomy and in fact the whole subject is illustrated by many diagrams and pictures. The subject of fertilization and of the dependence of plants upon wind and animals is illustrated at much greater length than is usual in ele...
