2) Mrs. Lloyd Edwards in The Garden LXXVII. («943) 485: 



»One spring a self-sown seedling Mossy Saxifrage appeared in my little rock garden. It 

 was probably a cross between S. Rhei superba and a cream coloured hairy variety called, 

 I t hink, S. hirta, as it had some characteristics of each; but it was a great improvement on 

 both in every way. This I named , Apple Blossom', and it gave me the idea of trying to pro- 

 duce some large flowered, bright coloured varieties by bybridising. 



I used the new seedling S. , Apple Blossom', S. Rhei superba and S. ,Guildford Seedling 1 

 and soon got some very beautiful larged flowered "Mossies of different shades of colour and 

 rigorous growth. 



About this time Messrs. Thompson and Morgan of Ipswich advertised among tlieir 

 novelties S. deeipiens hybrida yrandiflora. I bought a packet and crossed some of the re- 

 sulting seedlings with my own, to their mutual improvement. A fine red seedling I named 

 Ruby. This flowered twice in its first season, and was purchased by Messrs. Clibran's re- 

 presentative. He saw it in flower in the autumn and was much Struck by it. As S. Cliln 

 it has gained a considerable reputation. 



I continued selecting and cross-fertilising my best seedlings and produced Red Admiral, an 

 improvement on Clibranii in size and colour. 



I wanted a really blood red Saxifrage, free-flowering and of compact growth, and in time 

 got S. sanyuinea superba. It shows in its neat, finely cut foliage, that Guildford Seedling was 

 among its ancestors, and, as far as colouring is concerned, I think no redder Saxifrage can be 

 produced. In the process of obtaining it I got many beautiful rose coloured and shaded 8 

 frages, notably S. rosea superba, a very fine, free flowering early variety with dark st eins and 

 red buds; and S. Rose Beauty with beautifully shaped flowers with small centres which flowers 

 very late. 



There was an idea that S. deeipiens hybrida yrandiflora of Messrs. Thompson and 

 Morgan had been partly produced from S. yranulata; but none that I raised showcd any 

 trace of such parentage.« 



3) Georg Arends (Fortsetzung des Briefes vom 48. Mai 1916, vgl. oben anter 1 : >Sie 

 [,S. Rhei superba 1 ) spielte dann eine Rolle bei der Weiterzucht meiner Hybriden, wobei ich dann 

 auch auf den Bastard yranulata X deeipiens zurück jjrri ff, um dessen große Blüte und die stark 

 verzweigten Stiele bei nicht zu großer Polsterentwicklun^r hineinzubringen. Die Sorte <S. hybrida 

 splendens zeigt gleich nach der Blüte deutlich die knollige Verdickung der allerdings nicht 

 absterbenden Blatttriebe.« 



Si observationes sub nota 2 communicatae exaclae sunt, in formis hybridis Saxi- 

 fragae Clibranii S. granulatae genae non continentur; attamen ex nota 3 apparet, 

 plantas hybridas a cl. Georg Arends produetas S. granulatae genas itaque trium 

 specierum (S. moschata Wulf., S. caespitosa L. , <S. granulata L.) continere. I
