varieties, vvhen the highest standard of excellence was reached. 

 Small forms were produced, which have been designated Pom- 

 pone Dahlias (Fig. 34). These are more useful as cut-flowers, 

 and when well set up, quite as effective as exhibition plants. 

 They have attained as high a standard of excellence as the large- 

 flowered section. 



By the introduction of D. Jiiarezii, the Cactus Dahlia, quite 

 a new type of flower was introduced. Fanciers have taken 

 it in hand, and still further improved it for border-culture, 

 while the variety is a distinct feature at the autumn exhibitions. 

 About the time of the introduction of the Cactus Dahlia, there 

 was introduced a pretty form of D. variabilis, named Paragon. 

 It had single flowers like its first parent; but soon the single- 

 flowered varieties became popular, and now we find certain 

 amateurs rejecting the double-flowered varieties iti their seed- 

 beds, and saving only such as have flowers of improved form, with 

 single flowers (Figs. 35 and 36).
