Duchess — Unkuowu Variety 



Tliis mixture lias l)een fount! in a very few cases. The writers iiave not 

 seen the fruit of the stray variety, but the tree is readily distinguished from 

 Duchess by the sharper, more distinct serrations of the leaves. The leaf sur- 

 face is duller with a slight bluish cast. It lacks the depressions in the leaf 

 (about the size of hail marks on fruit) which are characteristic of Duchess. 

 (See Fig. 20.) Duchess often shows a distinct rosette of leaves as terminal 

 growth ceases, and these are not evident in the unknown variety. 



Winter Bauana — Maideu Blush 



These varieties closely resemble each other and are sometimes found mixed 

 in nursery rows. Maiden Blush trees are often less tall and of more narrow 

 upright growth, but the most distinct difference lies in the leaf serrations. 

 Those on Winter Banana are coarser, duller and often show a distinct tend- 

 ency to doubleness. Maiden Blush serrations are finer, more regular and 

 rather sharp. Maiden Blush leaves are generally smaller, and the leaf sur- 

 face shows a slight bluish cast not seen in Winter Banana. (See Figs. 12 

 and 13.) 



Kambo — Summer Rambo 



There seems to be some confusion among nurserymen over these two vari- 

 eties arising, no doubt, from the similarity of the names. When grown side 

 by side the two varieties are seen to be quite distinct. Summer Rambo is 

 comparatively tall, vigorous and spreading, while Rambo is shorter and more 

 upright in growth; also the lenticels are smaller. The leaf of Summer Rambo 

 is larger and more coarsely waved, with sharper, more distinct serrations. 

 The Rambo leaf is narrower, especially toward the apex. (See Figs. H and 

 15.) 



The Winesap Group 



The Winesap group of varieties is one of the most clearly defined to be 

 met with. It may be variously delimited, but here it may be best considered 

 as including Winesap, Stayman, Arkansas (Mammoth Black Twig), Paragon, 

 Arkansas Black, and Delicious. Mixtures of two or more of these varieties 

 are frequently met with in nurseries. 



Arkansas (Fig. 10) and Paragon resemble each other very closely. Al- 

 though sometimes considered identical, they can nevertheless be distinguished 

 from each other even as non-bearing trees; but Paragon has been studied too 

 little to warrant a statement of distingui.shing characters. Often the identity 

 of Paragon met with in nurseries may be doubtful. All the other varieties 

 may be distinguished with reasonable certainty. 



Winesap carries an earmark that separates it from all other varieties. This 

 is a small roundish leaf with very coarse dull serrations, shown in Fig. 8. 

 (Fig. 8 was erroneously named Stayman in Bulletin 208.) These leaves 

 may be few, but one or more will most certainly appear on any tree, even a 

 small one. The upper surface of the leaves shows a pebbly texture somewhat
