I do not know to which section S. sancta belongs — it does 

 not flower well with me. I should therefore be glad of any hints 

 which more successful growers can give, to ensure success with 

 this very interesting species. The Megasseas, or large-leaved and 

 large-flowered section, sometimes not included amongst the true 

 Saxifrages, are well known to everyone. They grow easily every- 

 where. The finest forms are S. cordifolia purpurea (Miss Hope's 

 variety), the lovely and early-flowering S. Stracheyi, which is 

 hardy, but apt to be cut off with spring frosts, and the Himalayan 

 S. purpurascens. The last two require to be grown on warm, 

 sunny borders. There are, in this section, many pretty hybrids, 

 raised by Max Leichtlin and others. Of these, I would mention 

 S. speciosa with flesh-coloured flowers, and S. Inglerestii, which 

 is the earliest to flower after S. Stracheyi. 



I may mention that in the preparation of this short paper I 

 am indebted to the practical help of Mr. Pritchard, under whose 

 care the fine collection, formed by the late Mr. Atkins of Pains- 

 wick, which passed to me, has suffered no deterioration. 



CULTURAL AND DESCRIPTIVE NOTES ON THE 

 GENUS SAXIFRAGA. 



By Me. G. Reuthe, Tottenham. 



[Bead March 12, 1889.] 



As the scientific aspects of this genus have already been treated 

 of, I shall content myself with drawing attention to a few of the 

 best members of it suitable for decorative and garden purposes, 

 and I shall endeavour to give a few hints in regard to their 

 cultivation. 



Before attempting to grow Saxifrages, or, indeed, any plants, 

 we ought to know something of their requirements — whether 

 they are found in their native habitats in moist, dry, shady, or 

 sunny positions. For instance, if we plant S. Fortunei and S. 

 longifolia in the same position, it would undoubtedly end in 

 failure with either the one or the other. We find the species of 

 the Euaizoonia and Kabschia sections (representing the encrusted 

 Saxifrages), which, in my opinion, are the most interesting and 

 showy of this genus, are, with few exceptions, natives of the
