p72 F. Slaughter. How to Grow Tea Roses.  
If it is required to grow Tea Roses with a view to exhibiting they should undoubtedly be grown on half standards, about three feet high, and to start with only grow the stronger varieties, such as the following twelve: Innocent Pirola, Medea, Madame Jean Dupuy, Madame Jules Gravereaux, Madame Leon Constantine, Maman Cochet, Molly Sharman Crawford, Mrs. Foley Hobbs, Mrs. Hubert Taylor, Souvenir de Pierre Notting, White Maman Cochet and W. R. Smith. 

p77. Ibid. The twelve varieties mentioned earlier are all suitable for ordinary gardens with the exception of Innocente Pirola and Medea, which I should not recommend for any purpose but exhibition.
