Figs. 99 and 100 re- present a flower in a yoiing state seen from above. After this, however, follows a whorl of six elements. Fig. lOlshoAvsaflower at a somewhat later stage than is represented at fig. 100. In fig. 101 the sepals are removed, and only two of the petals drawn. Fig. 102 represents a very perfect ti’ansA^erse section, shoAving all the jAai-ts of the floAvei*. It might, perhaps, be sujiposed that there Avere tAvo Avhorls of anthers, each whorl containing four elements, and that tAvo of the elements of these AA'horls AA'ere aljortiA'e; but that this cannot be so is shoAAui by the regular jAosition of the six anthei-s in one Avhorl, Avhich ahvays occurs in good specimens.
