This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1901 edition. Excerpt: ...and construct a longitudinal section of the entire flower on the plan of those shown in Fig. 155, but showing the contents of the ovary. 207. The Flower of the Buttercup.--Make a diagram of the mature flower as seen in a side view, looking a little down into it. Label the pale greenish-yellow, hairy, outermost parts sepals, and 1 Notice that the word cell here means a comparatively large cavity, and is not used in the same sense in which we speak of a wood-cell or a pith-cell. 2 The section will be more satisfactory if made from an older flower, grown out of doors, from which the perianth has fallen. In this case label the contained objects seeds. 3 Consult also the footnote on p. 193. One will do for an entire division of the class. the larger bright yellow parte above and within these petals, and the yellow-knobbed parts which occupy a good deal of the interior of the flower stamens. Note the difference in the position of the sepals of a newly opened flower and that of the sepals of a flower which has opened as widely as possible. Note the way in which the petals are arranged in relation to the sepals. In an opening flower observe the arrangement of the edges of the petals, how many entirely outside the others, how many entirely inside, how many with one edge in and the other out. Cut off a sepal and a petal, each close to its attachment to the flower; place both, face down, on a sheet of paper, and sketch about twice the natural size and label it x 2. Describe the difference in appearance between the outer and the inner surface of the sepal and of the petal. Note the little scale at the base of the petal, inside. Strip off all the parts from a flower which has lost its petals, until nothing is left but a slender conical object a little...
