The names given to the different patterns embody the principal 

 features of coloration on the basis explained above (see pp. 13 and 14). 

 The patterns selected are with one exception those that appeared as con- 

 spicuous bud variations and which are sufficiently distinct for ready 

 identification. Numerous other types that are intermediate between 

 the types given could also be designated by still more exact classifica- 

 tion. The following descriptions, together with the colored plates
