ON THE STRUCTURE OF BUDS 147 



distinct, broad, oblong stipules, with a leaf between 

 them (fig. 257). Other buds showed that the fifth 

 or often the seventh scale had reached this stage ; 

 so that individual buds vary according to size, vigour, 

 and other circumstances. The stipules have a midrib 

 and overlap one another. All the leaves are condupli- 

 cate, alternate, and distichous ; and as they lie against 

 the sides of the axis, with their edges to the sky, it 

 follows that when figured on a flat surface their edges 

 appear to be turned in opposite directions at each alter- 

 nate leaf. 



The eleventh pair of stipules (fig. 258) in the same 

 bud were very unequal, the outer being the larger, 

 oblong, and having the edges of the leaf lying beneath 

 it as usual. The inner stipule was oblong-subulate. 

 The stipules of the twelfth pair (fig. 259) were also un- 

 equal, the larger one being oblong-lanceolate and the 

 smaller linear. The leaf-blade equalled its stipules in 

 length. The thirteenth pair (fig. 260) and the four- 

 teenth were unequal in length and width, but both 

 linear. The leaf-blades of these two were longer than 

 their stipules, but the slender apex is sometimes, at 

 least, crumpled up beneath the apex of the stipule. 



The larger of the two stipules of each leaf lies on 

 the upper side of the branches or shoots bearing them. 

 The leaves are all conduplicate in bud, acuminate, and 

 penninerved, with closely approximate nerves. The 

 two parts of the leaf are unequal, but this is scarcely
