 (See Gardeners^ Chronicle, 1847, p. 171, for this and similar facts.) 

 In the Double Cherry, the pistil is almost always to he found in the 

 form of a leaf; and hooks 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. XIX.). Eose-buds are frequently 

 seen growing out of Roses. A very striking and uncommon accident 

 was observed by the late Mr. Knight in the Potato (Fig. XX.), 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 fruit is often found in the 

 state of a short branch. Still more rarely a flower lengthens, and 

 produces from the axils of its parts other flowers arranged over its sides, 

 as in the Double Pine-apple of the Indian Archipelago.
