In the Eose, the sepals and pistil are frequently changed into leaves ; in the Double Cherry, the pistil is almost always to be found in the form of a leaf; and books on structural botany abound in the records of similar cases. It sometimes happens that buds are not only formed, but developed, at the axils of the parts of a flower, as in a Celastrus scandens observed by Kunth, {fig. 11.) In the Pear, it is not uncommon to find two or three small pears growing out of an older one {fig. 12), each of which pears may be traced to the axil of some one of the parts of the flower; and rose- buds are frequently seen growing out of Eoses. A very striking and uncommon case of this sort was observed by the late Mr. Knight in the Potato {fig. 13), whose flowers produced young potatoes in the axils of the sepals and petals.* Occasionally, the centre of a flower lengthens and bears its parts upon its sides, as in the Pear and Apple, whose fruH is. * Proceedings of the Horticultural Society, vol. p. 89. fig.
