A study of actual cross-sections of leaf -buds will make the 

 truth of the previous statements more clearly evident. Hof-

meister's figures,* several of which are here reproduced (Figs. 



130, a, to 130, d), show 

 that in all cases the leaf 

 rudiments occupy in 

 the bud the positions in 

 which they meet with 

 the least resistance. 

 This is beautifully 

 shown in the leaf-bud 

 of the Hemlock Spruce 

 (Fig. 130, a). In. the 

 leaf-bud of the chest- 

 nut (Fig. 130, J), the 

 large stipules form the
