the Japanese bulbs, amongst which are several splendid forms. They do 

 not suffer from disease like Harrisii, and the flowers seem to have more 

 substance in them, though a point in favour of Harrisii is its height, 

 which is a great advantage. Another form of Lillum longiflorum which 

 commends itself very highly for pot culture is alho-mcmjinatiim. This 

 makes a lovely pot-plant, the colour of the foliage blending so beautifully 

 with the flower. (Fig. 219.) 



Lilies of the Martagon group really want establishing for a year in 

 pots before forcing to any extent, because, making no stem-roots, they 

 have only the basal ones to depend upon. If potted early, before these 

 commence growth, they will flower satisfactorily the first year. I have 

 grown Martagon album and Szovitsiamim well in pots, but on the whole 

 I do not recommend Martagon Lilies for pot culture ; they will succeed 

 much better in the open. 



This concludes my remarks in reference to Lilies for forcing for 

 decorative effect, and I think that those who require a large display of 

 flowering plants under glass during May will find in these Lilies subjects

that will well repay them, and give an additional interest to their conser- 

 vatory and greenhouse. 



I will now pass to the second portion of my remarks, viz. that 

 of growing Lilies in an unheated glass structure during the summer 

 months. This method, to my mind, is most enjoyable and successful, 

 as with few^ exceptions all Lilies may be grown in a cool shady house 

 and developed to their full beauty, protected from wind and rain and 

 adverse climatic conditions. In such a structure the reciuisite degree 

 of atmospheric moisture can be maintained, shade and water supply are 

 under control, and, generally speaking. Lilies can be afforded exactly those 

 conditions under which thev m-ow in their native habitats. All those 

 Lilies pre^dously mentioned will thrive under these conditions, for 

 naturally Lilies that are suitable for forcing will succeed under glass 

 in a cool temperature. L ilium auratum and its many fine forms can be 

 grown to perfection, the flowers slowly developing and growing to a grand 

 size. I have been more successful with L. auratum in this way than in 

 any other. 



Lilium speciosum, in its various forms, is indispensable. I would
