POSTSCRIPT 



While this book was in the press the recent Con- 

 stitutional changes in Ireland incidentally deprived me 

 of my garden. The collection at Knapton has therefore 

 been dispersed; a certain number of specimens remain 

 in my hands, but most of the larger I have presented to 

 the Royal Botanic Gardens, Glasnevin, Dublin, where 

 they will be found planted out on a grassy slope beside 

 the Rock Garden.
