Sometimes the flower-stalk is not efiectually checked in its growth by the development of the flower, but is prolonged through it, and produces secondary flowers in the midst of the organs of the first. This is not unfrequent in the rose. Several instances of these malformations are exhibited below. (Fig. 6.) k. This mode of studying the floral structure is deeply interesting and instruc- tive, but our limits will not permit us to dwell upon it, nor is it necessary. The intelligent student will be able to extend the above illustrations by an examina- tion of almost any flower, with reference to its deviations from the normal FIG. 0. — 1, From Lindley, —a flower of white clover, reverting to a leafy branch ; 2, liern drawn from a living specimen, —a tulip, 6, a leaf arising from the peduncle, takes the posi- tion, form, and color (in pan) of a sepal j 3, here drawn from a living specimen, —a rose (R. dmmascena) %vith the axis prolonged into secondary rose-buds. #*^^ In our detailed description of the flower, we shall commence with those organs which are deemed essential, their mysterious agency being indispensable to the perfection of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Wood, Alphonso, 1810-1881.
