244 GENERAL REVIEW. 



spring. Seed may be obtained from well-grown plants of the 

 single - flowered kinds, but cross - fertilisation is necessary. 

 Imported seeds may be sown in light sandy soil in a bottom- 

 heat of 70 to 80; but if the object is merely to reproduce the 

 plants, then cuttings are in every way preferable. Small 

 flowering-plants of G. radicans, G. florida, or G. Fortunei may 

 easily be obtained by taking off the branches of a large plant 

 after the flower-buds are set, and striking them separately in 

 small pots, in the gentle bottom-heat of a close propagating 

 case. Every branch will root readily in a week or two, and 

 they may then be removed to a warm stove, and placed 

 near the light to open their flowers. 



Ixora. A showy genus of stove - shrubs, principally E. 

 Indian, readily propagated by cuttings of the young wood 

 inserted in sandy soil, and plunged in a bottom-heat of 70 to 

 80. Seeds may be obtained from nearly all the species by 

 fertilising the flowers, although not unfrequently seeds are 

 produced without artificial assistance. Mr Fraser of Lea 

 Bridge has raised some very beautiful orange-flowered varieties 

 from seed, /. Fraseri (1874) being one of the best. Messrs 

 Cole & Son, Withington, Cheshire, also raised a fine pure 

 white-flowered hybrid (/. alba x I. cocdnea) a few years ago, 

 which was distributed in English gardens under the name of 

 /. Colei (1870). There seems every reason to believe that 

 this genus will be much improved, as seedling plants vary 

 much in habit and colour. /. Williamsii, I. amabilis (L 

 floribunda-nana), and /. Prince of Orange, are also seminal 

 varieties, raised about 1873-74 by Mr Fraser. In speaking of 

 these new varieties, the ' Florist ' says : " It is something new to 

 treat the Ixora as an annual. Nevertheless, Mr Fraser gets 

 seedlings to bloom freely at about one year old, the plants 

 yielding many new tints of colour, no two coming exactly 

 alike. This method of growing dwarf, bushy, free-flowering 

 examples of the Ixora, is worthy of adoption in establishments 

 where plants of this kind are in demand for decorative or for 

 market purposes." Ixora coccinea was introduced in 1690, but 

 having been lost it was again propagated from imported seeds 

 in 1775 (see ' Bot. Mag.,' t. 169). Ixoras maybe grafted in 

 a warm humid case with facility, either by whip, splice, or 

 veneer grafting, and this plan is very useful in renovating 

 exhibition specimens. 



Rogeria. A small gr'oup of herbaceous plants or shrubs, 

 represented in our gardens by Rogeria gratissima and one or 

 two other less well known species, principally natives of the 

 African continent. Rogeria may be propagated either by
