Not illustrated. 1897 edition. Excerpt: ... CHAPTER I. Outlines Of General Morphology And Natural History Of Phanerogams And Ferns. In this chapter an attempt is made to give such an outline of these subjects as may help to guide anyone in studying them in a botanic garden or in the field, and such as may also serve in rendering more intelligible the later chapters, where a knowledge of the elements of these subjects is taken for granted. The outline can be filled up in detail by reference to Part II. and by the actual study of the plants. Until lately, morphology has been a most formal science, and this formality still survives in the text-books most commonly in use. The older workers started from the flowering plants and even from the higher types of these, and either neglected the lower types of vegetation, such as ferns &c., or treated them in a summary way as 'exceptions' to which the 'laws' and 'rules' of morphology were not applicable! It is now recognised that this method of procedure is erroneous, and that the morphology of the higher plants can only be understood by reference to, and should be expressed in terms of, that of the lower. At the same time we must beware of starting too low in the scale, for there is a great gulf between the Pteridophyta and the Bryophyta, the leafy plant in a fern not being the equivalent of that in a moss or liverwort (see Pteridophyta in Pt. II.). The Pteridophyta (ferns &c.) and Spermaphyta (flowering plants proper) however, may fairly be treated together. Most text-books deal with morphology apart from physiology or any other branch of botanical study, thus rendering it extremely dry and unintelligible. A particular 'type' of stem, for example, is chosen and described and then other varieties are treated of in order under the title of...
