Gardens, Royal, in England. Anon. (Gard. Mag. No. 2537. 

 Supplement). — A descriptive account of the King's private gardens at 

 Windsor, Sandringham, Osborne, and others, accompanied by excellent 

 illustrations. — W. G. 



Gas Liquor. (Bol B. Soc. Nac. Hort. iv. p. 95, 1902).— Attention 

 is called to the value of the water of condensation at gas-works as a 

 fertiliser. An exceptionally heavy crop of Sugar-Beet, yielding on analysis 

 a very large percentage of sugar, resulted from its use. It is important 

 that it should be applied to the land some weeks before the seed is sown.

Gazania, Hybridisation of. By C. Sprenger (Bull B. Soc. Tosc. 

 Ort. 10, p. 313, October 1902). — All known species are natives of South 

 Africa, and extend as far as the Equator, where they are found chiefly on 

 the higher mountains. They are more or less perennial, woody and 

 evergreen, sometimes even shrubby. Some species, e.g. G. nivea and 

 G. pygmcea of Natal, have caducous leaves. Besides G. splendens, which 

 is an old hybrid emanating from some English garden, we only possess 

 in cultivation the following : G. coronopifolia, G. longiscapa, G. nivea, 

 G. Pavonia, G. pinnata, G. pygmcea, and G. rig ens. G. splendens, 

 introduced into Italy since 1860, is sometimes used for borders or for beds. 

 In the author's garden, besides above species, occurs also G. montana, 

 with yellow flowers, which was introduced by him and published in 

 " Gartenflora " of Berlin. He also obtained from Lemoine the hybrids 

 G. coronata, G. diademata, and G. nivea latiflora. Some other species, 

 possibly natural hybrids, also came from South Africa. With all this 

 material he began the operation of hybridisation, and with splendid 

 results. He had also some species of Arctotis and Garteria, natives of 

 South Africa, and closely allied to Gazania. The various hybrids he 

 obtained are then enumerated and vividly described ; they are the follow- 

 ing : G. vomer ensis (G. rigens x G. nivea) ; G. elmensis (G. rigens x 

 G. splendens) ; G. Italia (G. splendens x G. rigens) ; G. Arctotis 

 (parentage uncertain) ; G. Firenze (parentage uncertain) ; G. romana 

 (G. nivea x G. Pavonia) ; G. Trinacria (G. pygmcea x G. rigens) ; 

 G. illustris (parentage unknown). 



Fecundation of Gazanias is comparatively easy, and should be 

 undertaken in bright sunshine and when the flowers are fully open and 

 mature. Hybrid Gazanias have also been obtained in Stuttgart, Nancy, 

 and Erfurt, besides those already mentioned as obtained in England in 

 1860. Crossing between Gazania and Garteria is difficult ; the former 

 will probably cross more easily with Arctotis. — W. C. W. 



Gentians. By G. Magne (Le Jard. Sept. 5, 1902, p. 263).— Their 

 kinds described according to the quarters of the world of which they are 

 natives, with hints on the cultivation of each. — C. W. D. 



Geraniums, Culture and Distillation of. By F. S. Margiochi 

 (Bol. B. Soc. Nac. Hort. iv. p. 70 1902). — Some interesting notes are 

 given respecting the cultivation of Geraniums for the purpose of distilla- 

 tion. It appears that essence of Geranium is used for adulterating
