The nature oj the upper surface of the leaf is worthy of attention in identification 

 work. Although in the majority of pear varieties the leaf surface is smooth as 

 in Flemish Beauty; in a few, it is more or less distinctly and usually very finely 

 bullate (pebbled or blistered) as in "False Bosc" (Figure 9). Also, the leaves of a 

 few varieties are slightly rugose (wrinkled or uneven) as in Seckel. The rugose- 

 ness is sometimes confined to the section along the midrib as in Garber (Figure 9). 

 Sometimes a variety has essentially smooth-surfaced leaves with occasional 

 large, shallow depressions as in Clairgeau or Ovid. In some varieties, as Lincoln, 

 the principal veins are numerous. In Willard they are distinctly raised, while in 

 Koonce they are depressed (Figure 10). In a few cases, as in Kieffer, the net 

 veins are uniformly depressed (Figure 9). A further characteristic of the upper 

 leaf surface concerns the presence or absence of pubescence. In most pear 

 varieties the leaves are not pubescent, but in some, there is more or less pubescence 

 as in "False Bosc" (Figure 10) or Koonce.
