PLATE 47 
t .—Vertical section of outer part of the proliferations just below the surface shown 
on Plate 5. Here are well-developed tracheae (at T) and long, twisted cells (incipient 
vessels) strikingly suggestive of crowngall irregularities. X160. 
2.—Vertical section in same region as figure 1, but at another level, showing distorted 
vascular bundles in the new growth. The arrow shows the direction of the pith cav¬ 
ity, and the tissue at the top shows the beginning of the outermost proliferations—that 
is, those into the pith cavity. X160.
