The Origin of a Land Flora A Theory based upon the Facts of Alternation

Naturevolume 79pages14 (1908) | Download Citation



THIS important book, embodying the results of the author's well-known morphological researches during the last twenty years, may be regarded from two points of view. On the one hand, it forms a most excellent manual of comparative morphology for the groups dealt with—essentially the higher cryptogams; on the other, it gives the final statement of those theoretical views on the alternation of generations in plants with which Prof. Bower's name is associated and of which he is the leading champion. The two aspects cannot, however, be kept separate; the theory forms the thread on which the facts are strung, and without the theory we should not have had those researches which have so greatly enlarged our knowledge of the facts. In this way the “working hypothesis” has fully justified its existence, and all botanists owe a debt of gratitude to the author for the theory which he has so systematically worked out, as well as for the detailed investigations to which it has been the guide. No more important contribution to scientific botany has appeared in England since the revival of botanical research in this country in the 'seventies of the past century.
