When the axis has attained a considerable length on the unfolding of the bud, the bases of the leaves generally grow at the same time in length and breadth, so that they entirely cover the surface of the enlarged shoot also, clothing it wiih a green cortex, in which the parts belonging to the separate leaves can be distinctly recognised. This is especially clear in Araucaria and many species of Pinus, but is very common also in other genera; in Thuja, Cupressus, Libocedrus, &c, the axis of the shoot is also completely covered with these leaf-cushions; but the free parts of the leaves are very small and often project only as short points or projections. The phyllotaxis is spiral in the Abietineae, Taxineae, Araucariex, Podocarpus, &c.; the Cupressineae bear whorls which, above the cotyledons, contain generally from three to five leaves, but usually fewer at a greater height on the primary axis. The secondary axes usually begin at once with decussate pairs, which, in bilateral shoots, are alternately larger and smaller (as in Callitris and Libocedrus); in Juniperus and Frenela the whorls on the secondary axes also consist of from three to five leaves, and are alternate; the pairs of leaves of Dammara stand at an acute angle to one another. The foliageleaves of most Conifers are very persistent, and may live for several years, their leafcushions keeping pace in growth for a long time with the increase in size of the axis; in Larix and Salisburia the leaves alone are deciduous in autumn, in Taxodium distichum the axes that bear them are also deciduous. The Flowers of Coniferae are always diclinous; either monoe...

Excerpt from Text-Book of Botany, Morphological and PhysiologicalThe historical development of botanical views and theories does not seem to come within the scope of a Text-book of Botany, and would only interfere with'the unity of design of the work. It would therefore be superfluous to quote scientific works which have only a historical interest. In the references which will be found in the work the chief object has been to introduce the student to those writings in which he will find a fuller discussion of those parts of the subject which have been only touched on briefly. In some cases the writings of others have been quoted because they represent views different from those of the author, and because it is desirable to place the student in a posi tion to form a judgment for himself. Others again of the references are simply for the purpose of citing the authorities on which reliance is placed for state ments that have not come within the range of the author's own observation. The reader of this work will at least learn the names and standing of those workers who have in recent times' contributed most essentially to the science of which it treats.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

Not illustrated. 1887 Excerpt: ...the direction of the rows of micellae in starch-grains and thick cell-walls,' &c. I consider that the quotation from my treatise, which had appeared two years previously, difiers from Schwendener's view just cited only in so far that it puts exactly the same ideas more in detail and more clearly, and at the same time directly contradicts Schwendener's older views (1877) on the relation of growth and cell-division. DEPENDENCE OF DI VISION UPON THE FORM OF THE CELL. the individual cells of which grow independently after each division; as in the genera Chlorococcus, Merismopedia, Telraspora, Glceocapsa, and many others. In more highly developed plants similar processes take place in the mother-cells of spores and pollen grains. In these cases the fact is particularly clear, that the mode in which the cell-divisions follow one another depends by no means on the physiological or morphological nature of the cells, but upon their mode of growth and external form--especially upon the latter. Fig. 267, for example, shows six different forms of cell-division in the pollen mother-cells of one and the same plant, the Orchid Neollia nidus-avis. In A the pollen mother-cell had approximately the form of a circular disc, which, by means of two divisions at right angles to one another, is cut lip into four quadrants. It is to be noticed, however, that the two vertical division-walls in Fig. A do not exactly meet one another, so that a small piece of the horizontal division-wall remains intercalated between the points where they join it: this intercalated piece of the previous division-wall appears like a breaking of it, and we meet with such interruptions of the walls very generally in the division oT tissue-cells, a point on which I lay some stress, because in the more...
