550 GENERAL REVIEW. 



by Mr John Duncan in some species of Saxifrage. The annual 

 species and varieties are readily propagated from seeds ; and 

 cuttings taken off in the autumn may be rooted and grown 

 in a sunny stove all the winter, such plants being useful for 

 blooming in the spring. The S. American, tuberous-rooted 

 species, seed occasionally, and the seeds germinate freely in a 

 genial bottom-heat of 65 to 75, or they may be increased 

 from herbaceous cuttings in heat by carefully grafting or 

 inarching herbaceous cuttings or young growths on bits of the 

 old tubers in a close case, or the old-established plants may be 

 shaken out in the autumn after the foliage has decayed, and the 

 tubers can then be divided. Careful selection has given us 

 numerous dwarf and free-blooming forms of T. majus, and 

 some of the other species are doubtless capable of improvement 

 in the hands of a skilful hybridist. 



T. Lobbii, T. majus, and T. Moritzianum have produced 

 numerous hybrid forms, and a great number of beautiful 

 hybrids have long been known between T. Lobbii and T. 

 Smithii. The following hybrids were known in French gar- 

 dens ten years ago : T. Louise Keller, T. massiliensis, T. Tri- 

 omphe du Prado, T. zandeir-grandiflorum, T. zipseri, T. zipseri- 

 majus, and T. Chaixianum. A new variety of T. majus was 

 raised a few years ago by Mr Miles of Cressingham, this being 

 known as T. Milesianum, Hort, and it deserves notice, being 

 perfectly hardy, having glaucous foliage, and vivid scarlet or 

 orange-red flowers i ^ inch across. 



T. canariense improved or T. fragrans (Barr and Sugden) is 

 a hybrid between T. canariense and T. majus, var. " Napoleon 

 III." partaking of the colour, shape, and freeness of the former, 

 so well known in every garden as a climber. Many attempts have 

 been made hitherto to cross it with other species without suc- 

 cess. . The colour bright yellow, with a deep crimson heart- 

 shaped spot on each segment of the flower, deeply and beauti- 

 fully fringed or scalloped. It was sent out in 1873. 



THE CAMELLIA AND TEA FAMILY (Ternstromiacece). 



A small order of evergreen plants, principally natives of 

 China, Japan, and N. India, the principal representatives in 

 our gardens being the numerous forms of Camellia. The Tea- 

 plant, which has done so much to found the commercial 

 prosperity of China, also belongs to this order; and Thea 

 bohea, a pretty evergreen shrub, is not unfrequently met with 

 in gardens, where it is grown as a curiosity. Its flowers are
