LESSON XIX. 



HOW THE LEAVES ARE FOLDED IN THE BUD 



^Estivation.— i^i^. 217. Valvate calyx, as of Mallow. Fig. 218. Sepals of Holly- 

 hock, — valvate-reduplicate. Fig. 219. Sepals of Clematis,— valvate-induplicate. 

 Ftg. 220. Petals of Flax,— contorted. Fig. 221. Petals of Wild Rose,— qnincuntial. 

 Fig. 222. Petals and sepals of Lily or Tulip. Fig. 223. Petals of Wall-flower,— 

 convolute. Fig. 22^. Petals of Pea, — vexillary. 



128. There is the leaf-hud^ consisting of many scales and 

 young leaves, folded up in such a manner as to occupy as 

 little space as possible ; and the fiower-hud., consisting of the 

 organs of the flower in their early state, also closely packed. 

 Now if you study the arrangement of the pieces composing 

 the bud of either sort, you will be surprised and delighted 

 with its variety and elegance. As each species of plant has 

 the same invariable mode of folding in all its buds, this study 

 well becomes a matter of science.
