C. Semi-Cos Varieties. 



The varieties we have grouped here are compact growing forms of a glossy 

 dark green colour and having characters more or less intermediate between the 

 Cabbage forms with tender leaves and the Cos with crisp leaves and wide midribs. 

 They make good hard close hearts, which are usually taller than their width, 

 unlike the Cabbage forms, where they are about as wide as high. The leaves 

 are thick. They require comparatively little space since their outer leaves 

 are more or less erect. They stand well without running to seed.

D. Cos Varieties. 



The Cos varieties are probably more grown as summer lettuces than any 

 others. Their crisp leaves recommend them to many to whom the more buttery 

 texture of the Cabbage varieties is less pleasing. So many self-hearting 

 varieties are now available that for summer use at least those that require 

 tying may generally be neglected. It is a curious fact, however, that even 

 varieties that are self-hearting find a more ready sale when they have a tie of 

 raffia around them than when this is omitted. The main variations are seen 

 in colour, size, and to a certain extent in time of coming to maturity. These 

 varieties were sown on May 5.
