VEGETATIVE FEATURES. 



256-258, 260, and 261 are figured. They are cut from 1 to 3 mm. apart ; and 



with the transverse sections preceding 246 they afford a series covering a vertical 



distance of nearly 3 cm., this being sufficient to include all the downward course 



of the peduncle (/) and surrounding leaf-trace bundles in question, through the 



cortex to their origin on the collateral bundles forming the woody cylinder of the

 saw cut prevents exact correspondence with the edge, s s, of sections 247, 250, etc. 

 The appearance of the section is entirely similar to that of the cortical portion of 

 a large radial section (392) traversing a neighboring cone. {Cf. photograph 4,
