respects similar to iudivisa, but more atitF and erect, and a sliade 

 darker green. This is a very hardy and cheap variety. 



Of late years a considerable number of new sorts have been intro- 

 duced, but as they all require a stove temperature, it would serve 

 no useful purpose to say anything about them. D. Guilfoylei, the 

 hardiest of recent introduction, is very graceful, and has slender 

 arching leaves, striped with white, red, and green. 



Dracaenas thrive well in a mixture of equal parts of brown peat, 

 silky loam, and leaf-mould, with a small portion of silver sand. They 

 require plenty of water at the root in the spring and summer 

 seasons ; but it is very injurious to them to water them overhead at 

 any time, as the water lo:iges round the heart and stem, and rots the 

 foliage at their base. I have seen many valuable plants rendered 

 unsightly by this treatment ; so I hope our readers will avoid it ; 

 and this applies more especially to Clordi/line inrlivlsa. In the 

 months of January and December, this plant should be very 

 sparingly watered at the roots, and not at all until it gets very dry, 

 and then only just give enough to keep the plant from being dis- 

 tressed, and prevent the cracking of the soil around the side of the 

 pot. I will add, in conclusion, that it will be necessary in the hot 

 days of summer to give them plenty of air by day , and before closing 

 the conservatory at night to well sprinkle the floor with water. By 

 so doing, it will keep away the red-spider from them, as well as arti- 

 ficially resemble the dews of night of their native habits. They 

 should be also shaded trom the hot rays of the sun, otherwise, the 

 edges of the leaves will become brown, and spots of the same colour 

 will appear on their surface, thereby partially destroying their 

 beauty. 



NOTES ON THE NEW ROSES. 



BY GEOEGE GOHDON. 



|S the present moment is most favourable for the purchase 

 of roses in pots, a few words on the new varieties now 

 being oifered for the first time will perhaps be interest- 

 ing to many readers of the Floral World. In the 

 purchase of continental roses the first year of their 

 being distributed in this country, there is of course a considerable 

 degree of risk, because we have to depend entirely upon the raisers' 

 descriptions, and they are mostly terribly overdrawn. The name of 

 the raiser is the best guide in making the selection, because some 

 raisers are most jealous of their reputation, and like the raisers on 

 this side of the channel, are very careful to allow none but really 

 good varieties to pass out of their hands. Others again are less 

 scrupulous, and whether they have been successful or not in the 

 raising of good flowers they send us over a given number every year. 

 The raisers upon whose productions the greatest reliance can be 

 placed, are : — Ducher, who has sent a fine lot of tea-scented and 

 noisette roses in his time: Gonod, from whom we have obtained 



May.
