 variety, as its name implies, of the above. It was intro- 

 duced into England as early as the year 1684. The

It would be useless to attempt a description of the 

 varieties of Tropceolum majus so constantly do they

 the older are forgotten and lost. All are well worthy of 

 cultivation, and some of the varieties should be in every 

 garden. We have seen a double variety, but it was evi-
