scales, as in the Beech, but within and opposite the 

 middle of the often bifid scale. 



The outer four stipular scales are coriaceous, dark 

 brown, brittle, more or less ciliate towards the apex.

FIG. 254. -The seventh scale. FIG. 255. The eighth scale. 



FIG. 256. The ninth scale, showing fusion, which is unusual. 



FIG. 257. Members at the tenth node : o.st., outer stipule with a portion removed to 



show the leaf, I, which comes next in order ; i.st., inner stipule. 

 FIGS. 258-260. Members at nodes 11 to 13 ; o.st., outer stipule ; Z, leaf; i.sL, inner 



stipule. All are separated to show outline. 



Owing to their being connate, however, the single 

 piece occupies the central position of the leaf, the 

 blade of which, if present, would be between them. 

 These four scales do not elongate in spring, being prac- 

 tically dead ; they often split at the apex into four or 

 five teeth.
