THE BOOK OF CHOICE FERNS. 



As illustrative of the above statements, it has been thought advisable to 

 publish here as complete a list of garden hybrids, or supposed hybrids, 

 already in existence, as could be made : the number goes on steadily 

 increasing every year. Had it been possible, we would have given the names 

 of the parents ; but, although some forms apparently partake of the distinctive 

 characters of two decided species already in cultivation, the production or 

 procreation of the greatest number of them is too problematic, and their 

 parentage, as at present known, is too uncertain, to warrant the advisability 

 of such an undertaking. 



Besides endless garden and naturally - produced abnormal forms of 

 Aspidium (Polystichurn) aculeatum angulare, Asplenium (Athyrium) Filix- 

 fcemina, Nephrodium (Lastrea) Filix-mas, Polypodium, Scolopendrium, and 

 other hardy British Ferns, the following are all the varieties of garden origin 

 at present known. The plants marked with an asterisk (*) require stove 

 temperature : all the others thrive admirably under cool treatment. For 

 stove and greenhouse temperatures, see page 27.
